The Basics of Asphalt Paving

by Posted in Concrete Contractor Tagged , , , ,

Asphalt Paving Charleston SC requires careful planning and execution to ensure quality results. It starts with grading to get the desired slope and profile. Next comes a strong aggregate base that enhances the load-bearing capability of the asphalt surface.

The hot asphalt mix is carefully formulated at an asphalt plant. It must be kept at a high temperature during the paving process in order to achieve proper compaction.

A sub-base is a layer of well-graded material laid on top of the ground to form the base upon which an asphalt surface is constructed. It may be omitted where there is only pedestrian traffic, but it is an essential part of any paving that will be used by vehicles. Sub-bases can be either bound or unbound, and there are a number of different materials that can be used to achieve the right level of performance for any given pavement. These materials include crushed stone, slag, fly ash and recycled aggregates. All are designed to provide good load-spreading and drainage properties when correctly laid and compacted.

The choice of sub-base material can have a considerable impact on the cost and quality of any paving project, so it is important to consult with your contractor at an early stage to discuss the best solution for your particular site. In general, a sub-base should be built up as a series of layers no deeper than 150mm. Each layer should be thoroughly compacted before the next is placed on it. This helps to ensure that there is no risk of settlement when the pavement is opened to traffic.

For larger projects such as roads and highways, it is recommended that the sub-base be constructed using a type 1 or type 2 construction graded granular material. This provides a durable, hard wearing and economical foundation for construction work. It also helps to avoid pumping of fine-grained soils beneath pavement edges and joints, which can occur when three conditions are present in combination: a pumpable soil; excess water; and frequent heavy truck loading.

It is not possible to build an asphalt surface over a poor sub-base without risking damage and subsequent costly repairs. A good quality sub-base can help to prevent weed growth and improve drainage around the paving slabs, which can help to prolong their life. If a paving contractor tells you that a sub-base is not required underneath your driveway, ask them how they plan to spread the load of the paving and what guarantee they can offer against future movement and settlement.

Binder

Asphalt is a versatile material used for a wide variety of applications including roads, driveways and parking lots. It is durable and easy to maintain. In addition, it is a greener choice than concrete because it uses less energy and emits fewer greenhouse gases during production.

The main components of asphalt are aggregates (like rocks, sand and gravel) and bitumen, a sticky black petroleum-based substance that holds the aggregates together. These ingredients are mixed and then baked together to create a hard, dense pavement. In recent years, the industry has been making great strides in improving the environmental footprint of asphalt paving. These advancements include Warm Mix Asphalt (WMA) that reduces the production and placement temperature of the asphalt mixture by 30°F to 120°F, which in turn lowers fuel consumption and cuts emissions.

WMA also requires the use of recycled asphalt shingles, a valuable resource that can be reused in the asphalt mixing process without losing its performance characteristics. The use of this recycled material reduces the need to purchase virgin asphalt, which in turn saves taxpayer dollars. Another green advancement is the use of porous asphalt, which has tiny holes that allow water to pass through the pavement into the ground beneath. Porous asphalt has the added benefit of melting ice and snow quicker than traditional pavements.

Before laying the asphalt, the contractor prepares the site by grading and sloping the ground so that water drains away from the new surface. This step is particularly important for rural roads where the pavement may be subject to higher volumes of water traffic.

Once the grading and sloping have been completed, a layer of coarse aggregate is laid as a base course. This is followed by a layer of stronger, load-bearing asphalt binder. The binder is commonly a hot mixture that is kept in a heated silo until it can be transported promptly to the job site. The asphalt must be kept hot throughout the paving process because if it cools it becomes too stiff to be easily compacted with roller machines.

Because REOB is a waste product, the composition of different batches can vary widely, even from the same producer on different days. To combat this, the TFHRC developed a test to compare the composition of REOB and asphalt binder samples from State highway agencies.

Surface

Asphalt is a popular paving material for roads, parking lots and driveways because it provides a smooth surface that resists skidding, which increases safety for vehicle drivers. It also helps reduce noise pollution. Its dark color makes it easy to see road markings and improves visibility at night, and its excellent traction helps prevent hydroplaning during rainy weather.

The paving process starts with clearing the area and excavation of the base materials, which can be either compacted stone or asphalt mix depending on the project requirements. Once the base is laid, it is rolled and compacted by specialized paving equipment to create a strong and sturdy surface. Proper drainage planning is an important step in the paving process as water accumulation can lead to pavement damage such as heaving and cracking over time.

Next, the sub-base and binder layer are mixed together to form a thick and durable asphalt mixture. The binder layer consists of large aggregates that are coated with a thick liquid called bitumen. The blending process ensures that the proper proportions of aggregate and bitumen are used. The mixture is then heated and dried to a workable consistency. It is then transported to the construction site while still hot.

At the construction site, the asphalt is poured and quickly rolled by multiple compaction roller machines to eliminate voids and improve density. The pavement is then left to cool and harden. Once the asphalt has cooled, it is safe for vehicle traffic.

Whether the asphalt is being used for a large highway or a small residential driveway, it must be properly installed to maximize its lifespan and performance. Proper installation includes testing the area for proper drainage and grading to ensure that water runoff is prevented from pooling in any areas where it shouldn’t be.

Compared to other paving materials, asphalt is one of the most environmentally friendly due to its minimal environmental impact and recyclability. It also requires less maintenance and repairs over its lifespan, which helps to save on both operational and construction costs. The cost efficiency of asphalt is a big reason why it remains the preferred paving material for many contractors and municipalities.

Maintenance

Asphalt is more affordable than other paving materials, but it requires routine maintenance to keep it looking and functioning its best. Regular sealing and crack filling can prevent damage and extend the lifespan of your asphalt paving, which can save you money in the long run. Asphalt is also recyclable, reducing the need for new materials and promoting sustainability.

When compared to other paving materials, asphalt has the added benefit of being skid-resistant, which makes it safer for both pedestrians and drivers. This feature helps reduce accidents caused by lack of traction, and is especially important in snowy or rainy conditions. Additionally, asphalt is easy to repair if a vehicle becomes stuck on it, and it will quickly revert back to its original condition.

However, asphalt can deteriorate due to traffic and weather over time. If left unattended, small cracks will expand, leading to water infiltration and temperature fluctuations. These changes can cause the aggregates to unravel and cause further damage underneath the surface layer of the asphalt.

It is important to have a professional asphalt contractor provide routine maintenance for your pavement to ensure it stays in good condition. These services include sweeping and cleaning to remove debris and dirt from the surface. The paving contractor may also apply a sealcoat to the surface, which protects against oil and gasoline spills, guards against oxidation, and protects the asphalt from harsh UV rays.

Pavement maintenance also includes repairing any potholes that appear on your property. These unsightly holes can not only impact the visual appeal of your parking lot, but they can also create tripping hazards for people who use your space. Having your asphalt potholes repaired promptly by a paving contractor can help you avoid the cost of tripping injuries and potential legal liability.

Asphalt is also versatile when it comes to design options, making it suitable for a variety of project types from elegant driveways to functional parking lots. It can be molded into many different shapes and colors to complement your architectural style, and it can even mimic the look of more expensive materials like brick or stone without breaking the bank.

The company should also be transparent about its prices and services. Choose one that provides cost estimates and offers a money-back guarantee. Also, find out whether it has insurance and is licensed by the State Department of Environmental Conservation.

Many pest control companies use chemicals in their services, which can be harmful to humans and pets. These chemicals are often derived from petroleum and can be absorbed into the bloodstream through skin contact. They can also cause breathing problems and other health issues if inhaled. Luckily, there are safer alternatives that can be used by professional pest control companies. For example, using naturally occurring products such as pyrethrins instead of pyrethroids can eliminate harmful pests without harming human or pet health.

In addition to price, it’s also important to consider the type of pest that needs treatment. For instance, a termite infestation requires a different treatment method than an insect infestation. This can be determined by asking the pest control company what types of treatments they offer and their success rates.

You should also look for companies that provide multiple methods of pest removal, such as spraying, baiting, and trapping. This will give you more flexibility in choosing the best option for your home. Moreover, you should also ask about the company’s pest control philosophy. For example, some companies rely heavily on pesticides while others rely more on bait and trapping methods. It’s also important to check how long the company has been in business, as this can indicate its experience and expertise.

Experience

Pest infestations can be a major problem for homeowners, especially when they become serious. While some of these pests are easy to get rid of with do-it-yourself methods, others require a professional. This is why it’s important to carefully vet the options available for pest control services before signing a contract. The best way to find a quality pest control service is to compare prices, services, and customer reviews from multiple companies. It’s also helpful to ask questions during the quote process, as this will help you determine whether or not a company is right for your needs.

In addition to pricing, you should also consider the type of pest you’re dealing with and how severe your pest infestation is. For example, rats can be very difficult to eradicate once they’ve established a nest in your home. Look for telltale signs of a rodent infestation, including gnaw marks on walls and baseboards, foul smells, and holes in window screens. Also check for bowed siding, shingle damage, and gaps in foundations or porches that can let rodents in.

Choosing the right pest control service is crucial for maintaining a clean, healthy environment. It is also an excellent way to protect your property value and ensure a safe environment for your family and pets. Fortunately, there are many good choices for pest control companies. The most reputable ones have extensive experience in the industry and offer a wide range of services.

They also offer preventative maintenance treatments to keep pests away from your home.

Customized Treatment Plans

Every pest problem is different and requires a customized approach. An excellent pest control service will conduct a thorough inspection of your home or business and provide a detailed treatment plan. This should include the type of pest(s) to be controlled, a description of the conditions that are contributing to the infestation, and recommended strategies. In addition, the pest control company should explain any preparation that you may need to do in advance (such as emptying drawers and cabinets and vacating the house).

A good pest control service will offer a range of services tailored to meet your needs, including one-time pest treatment and routine pest treatment plans. Routine treatments are typically necessary if you are experiencing a persistent infestation of the same pest(s). For example, cockroaches are difficult to get rid of without professional help. In addition to offering a comprehensive pest solution, a good pest control service will also offer customer service that is responsive and understanding.

The best way to find a quality pest control service is to choose a company that is licensed and insured. This will ensure that the company is using pesticides by local and state regulations. Additionally, you should look for a pest control service that offers a warranty on their work and will perform follow-up visits in case of any problems.

In addition, a good pest control service should be willing to work with you and your property manager to address your pest problems. This will ensure that the pests don’t reappear and can also help you avoid expensive repair costs. This is particularly important for commercial properties, where a pest problem can damage your reputation, cause loss of revenue, and lead to safety concerns.

Customer Service

A pest control service should provide a high level of customer service. It is important to keep in mind that customers want to be treated with respect and dignity, no matter the size of their problem. This is especially true for residential customers, who may be experiencing a very stressful situation. Providing a pleasant experience from start to finish will help customers feel comfortable in their homes and will make them more likely to return for future services.

It is also important to choose a company with a good reputation. Online reviews, testimonials, and recommendations are good ways to find a pest control service that meets your needs. Look for both positive and negative reviews, as this will give you a balanced perspective. You should also consider the company’s history and ask about any service guarantees. If the company does not offer a guarantee, it should at least be licensed and insured.

When you call a pest control service, the first interaction sets the tone for the rest of the relationship. The technician must take time to listen and understand the customer’s problems. This will allow the pest control professional to tailor the service to meet the customer’s unique needs.

In addition, the pest control company should explain their services and how they will solve the pest problems. They should also be willing to work with the customer to come up with a treatment plan. For example, if a pest infestation is in the home, the pest control company should be willing to treat the interior as well as the exterior of the home.

A pest control company that provides a great customer onboarding process is a great way to build strong relationships with customers. The onboarding process should include an in-person inspection, detailed pest analysis, and a clear communication of the pest management plan.

Pests spread germs and bacteria that can make you sick through bites, droppings or contact. They can also exacerbate existing health problems like allergies and asthma.

Monitor and evaluate the presence of pests to determine if they require control. Use only pesticides that are designed for the specific pest and apply them according to label instructions. For more information, check out Pest Control Knoxville TN.

Rodents

pests

Rodents, a diverse group of mammalian animals that includes squirrels, chipmunks, beavers, mice and rats, make up 40% of all mammals. They are found worldwide and live in a variety of habitats. Their unifying feature is a pair of sharp, curved incisors that are optimized for gnawing and chewing. They can also squeak to communicate with one another and have highly developed senses of sight, smell and touch. Some species are pests, destroying habitat and spoiling food stores, while others are important to the ecosystem as natural predators of other wildlife and scavengers of dead animals and plants.

Rodents can become a nuisance to humans when they invade homes and businesses, ruining property and creating a health risk through the spread of diseases that they carry. In addition, they can damage crops and create fire hazards from gnawing and chewing at electrical wires. Rodents can be managed as part of an Integrated Pest Management program with traps, bait stations, and exclusion tactics that stop them from finding entry points into buildings and relocating them to new areas.

Using traps rather than poisons to control rodents is safer and more effective. It gives you clear verification that the rodent has been caught and allows for a more humane treatment of the animal. It also reduces the odor of decaying rodents that can build up in walls and other out-of-the-way places, as well as the risk of exposure to children, pets, and other non-target animals. In addition, traps allow for a more environmentally sound treatment plan with the use of non-toxic baits and repellents, such as peppermint oil and eco-friendly ultrasonic devices.

Rats and mice can enter a home or business through small holes, cracks or gaps around pipes, vents, and windows. Sealing these spaces and regularly inspecting the home can prevent rodent infestations. Other preventive measures include storing food and water in sealed containers, keeping compost piles far away from the house, and avoiding the planting of ivy that can form “rat ladders” up to roofs and into attics.

Many rodents are useful to humans by providing a food source, fur for apparel and insulation, as test animals for biomedical and genetic research, and even as household pets. However, some rodents, such as the brown rat and the mouse, are serious pests, spoiling food, contaminating stored products, and spreading diseases.

Insects

Insects are the largest group of animals, with about a million described species, or types. They are hexapod invertebrates that have three-part bodies (head, thorax and abdomen), wings and three pairs of jointed legs. Insects are found in a variety of habitats on Earth, including the Arctic, tropics, deserts and caves. Most insects eat plants or other insects, and some are harmful to humans and animals. Insects sting or bite, and many spread disease-causing pathogens. Some destroy crops, damage forests and greenery, and infest homes and businesses. Examples of insects that are pests include Mediterranean fruit flies, gypsy moths, fire ants, termites and mosquitoes.

In a natural environment, insect populations are controlled by predators, parasites and herbivores. When these natural enemies are destroyed by pesticides, insect densities increase and the insects become a nuisance or damaging crop pest. This is why a comprehensive pest control program includes conservation of natural enemies as well as the use of chemical methods.

Classic biological control involves the introduction of natural enemies of a particular pest into the environment, either through mass release in the wild or through small-scale releases in controlled situations such as greenhouses. Care is taken to select natural enemies that are adapted to the life cycle, physiology and defenses of the pest, as well as to the site where they will be released.

The success of a biological control program depends on monitoring for the presence of the enemy, and removing the pests as soon as they appear. For outdoor pests, this means examining traps and other monitoring devices on a regular basis throughout the growing season. For indoor environments, a pest control program should include regular inspections and maintenance of food storage areas, garbage receptacles and vents to prevent the entry of unwanted creatures.

Insects are remarkably adaptable, and many use a variety of strategies to avoid capture or death. Behaviors range from the almost inert parasitic forms that lie in the nutrient bloodstreams of their host plants, to dragonflies that pursue prey in the air, and predaceous water beetles that outswim their prey.

Birds

When people think of pests, cockroaches and rodents tend to come to mind. But birds can be a major nuisance too, especially when they gather in large numbers around buildings and cause property damage or pose health risks for building occupants. Controlling pest birds is an important part of any facility maintenance program, and a proactive approach is needed before the problem becomes unmanageable.

Birds that impact facilities can include pigeons, sparrows, geese, and European starlings, among others. All these species flock in significant numbers and can damage the appearance of structures, block ventilation, cover security cameras, clog vents, deteriorate materials like metals and paints, and create other problems. In addition, their droppings are high in uric acid and can eat through roofing materials, erode concrete and steel, and contaminate food and water sources.

Depending on the species and the environment, different types of deterrents are available to prevent bird infestations. Visual deterrents, such as predatory decoys that mimic natural predators, are a non-lethal option that can be effective when placed in areas where birds commonly gather, such as on plaza decks. Audio deterrents, such as sound devices that emit ultrasonic sounds that frighten and disorient birds, can also be used in places where visual deterrents are not suitable.

For some species, trapping and euthanasia may be necessary. However, a proactive approach to prevention is a more efficient and cost-effective way to deal with bird infestations. Many architects and engineers now incorporate pest management plans into new facility designs to reduce the need for traps and chemicals.

Generally, the best strategy for bird pest control is to eliminate as many conducive conditions as possible around and within a facility. This can be achieved by eliminating all traces of food, water and shelter from the immediate area, as well as reducing the presence of any areas that attract birds (i.e. near a public landfill, sewage treatment plant or raw material mill). When these measures are not enough to discourage pest bird populations, the next step should be to use a comprehensive trapping and removal procedure to eliminate birds as quickly and safely as possible.

Other Small Creatures

Animals, like raccoons, opossums, squirrels, chipmunks and groundhogs, can become pests as they seek shelter or food in and around homes. Usually these animals are found outdoors but they can also rummage through garbage or set up residence in crawl spaces, attics and wall voids. They can cause damage to plants, trees and structures and may carry bacteria and parasites that are harmful to humans and pets.

Animals can be continuous pests that arc nearly always present and require regular control. They can also be sporadic or migratory and may only need control at certain times of the year. They may be predicted based on their natural history, climate, food availability and the presence of predators and other factors that affect their populations.

The activity of other small creatures often goes unnoticed because they are so common and are essential to nature. Insects, for example, pollinate many of the flowering plants we depend on for food and beauty. They also decompose waste, provide food for birds and other animals and help to spread soil nutrients.

Rodents like rats and mice are omnivorous and eat seeds, grains and fruits. They can also chew electric wires and lead to fires in homes. They can also carry diseases such as hantavirus pulmonary syndrome, leptospirosis and plague. Other small creatures that can be pests include ticks and fleas, which carry and transmit disease through bites.

Mole problems are widespread in yards and gardens. In the Pacific Northwest we have four separate mole species, the Coast Mole (Scapanus orarius), the Broad-handed Mole (Scapanus latimanus) and the Townsend Mole (Scapanus townsendi). They are known for their volcano-like, hill-shaped mole-hills and feed on earthworms, soil insects and grubs that they dig up while tunneling. Occasionally they will sample bulbs, root crops and sprouting seeds but most plant damage blamed on moles is really caused by meadow voles.
