The Advantages and Disadvantages of Asphalt Paving

Asphalt is an excellent choice for many types of parking lots. It’s easy to install, quick, and convenient. It also looks great.

Asphalt Paving

Asphalt Paving Fort Lauderdale is made with different materials, including aggregates (crushed stone, gravel, or sand), binders, and fillers. The right mixture is critical to the strength and durability of the pavement.

Asphalt pavements are categorized as flexible pavements and use an oil-based adhesive to hold the aggregate together. Concrete pavements, on the other hand, have a combination of sturdy aggregates and cement to make them stiffer and stronger. This enables them to distribute traffic load more widely and evenly across the subgrade.

Asphalt paving contractors have a range of equipment available to help them create the best quality product. They must be able to identify the best aggregate materials and test them against strict standards for durability. The quality of the aggregate will determine how long and well the asphalt lasts. The amount of maintenance required is another factor that affects the life and performance of an asphalt paved surface.

The strength of an asphalt paving material is determined by its ability to support the anticipated traffic load and the type of subgrade soil underneath it. The strength of the subgrade can be estimated based on its soil composition or can be tested using a tool such as a Dynamic Cone Penetrometer. A weak or unstable subgrade can lead to premature failure of the asphalt layer. It is important to ensure that the subgrade is strong and stable before paving commences.

Modern asphalt paving constructions use multilayer designs to increase the strength of the layers. These layers must be bonded together to resist wheel loads from heavy vehicles. To achieve this, the layers are covered by an asphalt tack coat that must be strong and uniform. If the tack coat is not properly applied, longitudinal cracking, fatigue cracking and rutting can occur.

To increase the strength of an asphalt paving mixture, fibers can be added to the HMA. These fibers are made of polypropylene, steel or glass and help to reinforce the asphalt mixture. They can also be used to reduce rutting, reduce the risk of cracking and extend the lifespan of the pavement.

While the strength of asphalt paving is superior to concrete, it still requires some maintenance. This is because the material tends to erode more quickly than concrete. However, if the pavement is regularly maintained with a seal coating, it can extend its lifespan and improve its appearance.


Asphalt is a durable material that is ideal for roads and highways. It is strong enough to withstand heavy traffic and weathering, and it can be easily repaired if necessary. It also resists damage from salt and other deicing chemicals, which is a big advantage in areas with harsh winter conditions. Compared to concrete, asphalt is less susceptible to cracking and crumbling due to the elements. It is also easy to clean and maintain, making it a great option for driveways and other surfaces that are subjected to frequent use.

The durability of asphalt depends on many factors, including the amount of traffic and the temperature. If these factors are not properly addressed, the durability of the asphalt will be impacted. In addition, the asphalt must be properly rolled and compacted. If the process is not done correctly, the pavement will crack and break down over time. The best way to avoid this is by using a professional paving company for all your needs.

During the production of hot mix asphalt (HMA), aggregate components are weighed and sifted. They are then dried by a rotary drum at a temperature of about 300 degrees. They are then reweighed as drying can alter their weight. Aggregates play a critical role in the workability and durability of asphalt pavements, and the surface textures and size of aggregate particles can also affect the skid resistance and ultimate load capacity of an asphalt mixture.

Aggregates are also used to create the base layer of asphalt. Once they are sifted and prepared, they are mixed with bitumen and other chemical admixtures. The resulting mix is then sprayed onto the road surface and compacted by rollers. It takes about 24 hours for the asphalt to cool and dry before cars can be driven on it.

A good asphalt mix must have a high flexural strength and stiffness to resist deformation. Moreover, it must be resistant to low temperatures and have good rutting characteristics and fatigue life. The dynamic modulus test is one useful method to evaluate the HMA’s durability. This test is a simple and inexpensive tool to measure the HMA’s fatigue behavior.


Asphalt is much more flexible than concrete, which can be a huge advantage in areas with heavy traffic. This flexibility helps to reduce the number of cracks and potholes caused by traffic or temperature changes. It also helps to prevent the pavement from becoming too hard, which can lead to rutting and other structural problems.

The flexible nature of asphalt also allows it to accommodate the movement of water underneath the surface. This can help to alleviate drainage issues and reduce the risk of flooding, which is often a problem for roads made from other materials such as stone or concrete.

There are a variety of asphalt mixtures available to meet different requirements. For example, high-strength mixes are used for roadways that are subject to heavy loads. These mixes require a higher binder content, which is necessary to ensure the strength of the pavement. Other asphalt mix types, such as low-strength and hot-mix, are designed for lower loads. These mixes are often a combination of recycled and unrecycled aggregates, along with bitumen.

Another advantage of asphalt is that it can be easily formed to create curved surfaces. This is especially helpful in areas with curves or tight turns. This feature can save time and money by eliminating the need for a permanent formwork, which is often required when building concrete structures.

Many factors contribute to the flexibility of asphalt pavements, including its amorphous properties and the arrangement of the aggregates within the mix. Aggregates are processed mineral materials, such as crushed rock, sand, gravel, and slags. The aggregates are held together by the binding agent, which is typically bitumen. The mixture also includes filler, which helps to improve the consistency of the material.

Flexibility can be enhanced by the use of additives in the mix, such as recycled material, polymers (e.g., styrene-butadiene-styrene), and other modifiers. These additives are designed to reduce the need for virgin raw materials, which can improve sustainability and cut construction costs. However, the addition of these substances may affect the grading and high-temperature grades of the asphalt.


Asphalt is generally cheaper than concrete, which can make it a good choice for large jobs like roads. However, the initial cost of laying asphalt is just one factor in the total project costs. It is also important to consider the cost of maintenance and repair, as these can significantly increase the overall cost of the project. It is therefore important to weigh the advantages and disadvantages of both materials before making a decision.

Asphalt pavements are made from a combination of aggregates (like rocks, gravel, and sand) and bitumen. The latter is a sticky, black petroleum-based substance that binds the aggregates together. It is produced at an asphalt plant, usually through a heating and blending process.

The material can be modified in a variety of ways to alter its properties and suit the local climate. For example, asphalt paving can be mixed with recycled materials to reduce its environmental footprint. For instance, reclaimed crushed cars and truck tires can be used as an additive to improve the durability of an asphalt surface and help reduce its costs. In addition, asphalt can be combined with recycled concrete to create a stronger and more durable road surface.

Another benefit of asphalt is its flexibility. It can be tailored to the climatic conditions of a particular region and can withstand rutting in summer and harsh freeze-thaw cycles in winter. The flexible composition of asphalt also allows it to be easily adapted for use under underground technical infrastructure, including power and telecommunication cables and district heating and water pipes.

In addition to being cheaper, asphalt is easier to maintain than concrete. Its surface can be sealed to keep out water and ice, which prevents cracks and extends its lifespan. Asphalt can also be repaired quickly if it becomes damaged.

However, it is important to note that asphalt has some disadvantages, too. Its dark color absorbs sunlight and heats up to 10 degrees hotter than concrete, which can cause safety issues. It is recommended to avoid walking on asphalt surfaces wearing flip-flops or any footwear with thin soles as the heat can blister your feet. It is also a good idea to keep your pet’s paws away from asphalt, as the material can burn them too.


Sealcoating Your Asphalt Driveway

Sealcoating is an inexpensive way to dramatically extend the life of your asphalt driveway or parking lot. It also helps prevent cracks and stains. To do it correctly, you need to prepare the surface for sealing. First, clear the area and wash it thoroughly.


Workers should wear masks when working with coal tar or similar asphalt sealers. These chemicals are skin and lung irritants. They must also allow the coating to dry for 24 hours. Visit to learn more.

Asphalt is subject to a lot of damage over time, from heavy vehicles, oil spills, UV rays and other elements. Sealcoating can extend the life of your asphalt surface by up to 20 years, saving you a substantial amount in costly repair costs. It also provides a nice, new-looking surface that is more attractive to prospective customers or tenants.

Asphalt pavement is made from rocks, stone and gravel that are held together by a binder that is petroleum-based. The deterioration of asphalt is caused by the degradation of this binder, which happens as rain and UV rays penetrate the surface. Sealcoating helps to prevent this deterioration by providing a thin layer of protection over the existing asphalt pavement.

The process involves spraying a thick coating of liquid over the asphalt surface. Workers then spread the material evenly with brushes or squeegees. This allows the sand and polymer additives to fill in the cracks and crevices. It also creates a non-slippery surface that is easy to clean. Some companies use a hot-mix asphalt for greater consistency and durability.

Once the sealcoating dries, it forms a protective barrier that blocks out water, sunlight and chemicals. It also protects against oxidation and prevents the formation of small cracks that can turn into potholes over time. This makes it important to get sealcoating done every two to three years.

Sealcoating is typically applied to asphalt surfaces such as driveways and parking lots. However, it is not a replacement for paving. It is best to use a professional to ensure that the process is completed correctly. If the job is not done properly, it can cause more harm than good.

It is important to note that oil spots should be repaired before the sealcoating is applied. If left unattended, these spots can leak through the sealcoat and soften the base layers underneath. The resulting damage can lead to faster deterioration and more extensive damage.

It is also a good idea to avoid heavy machinery or equipment on the newly-sealed surface. It can damage the sealcoat and cause indentation, which will shorten its lifespan. It is recommended that you schedule your asphalt sealing for the summer because humidity and cold weather can affect how quickly it dries.

It protects from UV rays

The sun’s UV rays can wreak havoc on asphalt, causing oxidation and fading. Sealcoating creates an impenetrable barrier against the damaging rays, keeping your pavement’s rich black hue intact for much longer. It also guards the surface against corrosive chemicals like gasoline, oil, and salt, preventing them from penetrating the surface.

Another of the sealcoating’s crowning achievements is its ability to thwart the emergence of cracks in asphalt surfaces. These fissures usually occur due to temperature fluctuations and exacerbate as moisture seeps into them, triggering further damage. The cracks may eventually lead to full surface failure, necessitating a costly replacement or repaving. Sealcoating effectively closes these gaps, minimizing the chance of further deterioration and saving you money in repair costs.

Sealcoating also shields the surface against water penetration, a major cause of pavement damage. This is especially important for a commercial or residential parking lot, where traffic is heavy. Water can cause serious structural damage to the asphalt base, resulting in potholes and cracking. The sturdiness of the asphalt’s base is also diminished when water penetrates and dries out, leading to further problems in the future. Sealcoating prevents this by creating a waterproof barrier and lowering the risk of structural damage.

Beyond its protective mantle, sealcoating also bestows a visual revival on asphalt surfaces. Over time, the sun’s UV rays can cast a fading spell on the asphalt, making it look dull and lacking in appeal. This ebony sheen is restored by the sealcoat, allowing it to take center stage once again and bolstering your curb appeal.

Whether you’re a commercial or residential property owner, the benefits of a sealcoat are undeniable. Unlike coal tar, which is hazardous to both humans and the environment, specialty resins are non-toxic and eco-friendly. However, if you want to get the most out of your sealcoat, it’s imperative to hire a professional asphalt paving contractor. This will ensure that the job is done right and that you’re using high-quality materials. A reputable contractor will also provide you with an estimate of the total cost of your project before starting.

It prevents water from penetrating the surface

Asphalt is one of the most important materials in modern construction, and it’s used to create everything from driveways to parking lots. It’s also incredibly durable, but over time it can become damaged by sun exposure, traffic, and weather. This damage can lead to cracking, fading, and other issues that require costly repairs.

Sealcoating is a low-cost maintenance option that can prevent these problems and extend the life of your pavement. It works by filling in surface voids, reducing the penetration of water into the asphalt, and protecting the pavement from oxidation. It’s also an excellent way to beautify your property’s curb appeal, as it gives the surface a deep black look that is attractive and inviting.

When untreated, asphalt begins to deteriorate as soon as it is exposed to sunlight and oxygen. This oxidation breaks down the aggregate and causes cracks to form. Seal coating stops this process by providing a protective barrier against the elements and prolonging the life of your pavement.

Another enemy of asphalt is water, which can penetrate the pavement and cause damage by softening the base. If this is allowed to happen, the pavement becomes brittle and less resistant to pressure from vehicle tires. Sealcoating prevents this by providing a seal that blocks moisture and protects the pavement from sinkholes, depressions, and potholes.

Oil and gasoline spills are another common enemy of asphalt, as they break down the material and create stains that are difficult to clean. However, professional-grade sealers contain additives that help the sealer resist these substances. The sealer also fills in surface voids and reduces the depth at which oil or gasoline can penetrate the asphalt.

Finally, sealcoating helps to repel salt, which can eat away at the asphalt surface. This is especially problematic in cold climates, as the salt will eat through the asphalt and cause severe damage. Seal coating steals the power of salt and keeps it from destroying your pavement, protecting it from deterioration and saving you money in the long run.

It adds a new layer of protection

Sealcoating adds a layer of protection that acts as an adhesive to the asphalt and helps it resist chemical penetration, UV rays, water, oil, and gasoline. This will prevent the oxidation of the top layer and help your asphalt last longer. In addition, the sealant fills in small cracks and makes it easier to clean your asphalt. This protects the asphalt surface from the elements and keeps it looking new.

Seal coating is made from refined coal tar and contains additives such as petroleum byproducts, rubber, and a variety of mineral fillers and aggregates. The additives are added to varying degrees to improve the performance of the sealant, such as drying fast, changing sand suspension, increasing water repellency, or adding resistance to salt and petrochemicals. The petroleum byproducts in the sealant also provide anti-aging properties and ensure that the pavement will stay strong and durable.

An unsealed driveway or parking lot is vulnerable to damage from the sun, rain, and snow. Water is particularly damaging, as it seeps into the small cracks and then freezes, which causes the cracks to grow wider. Seal coating protects the surface from water damage by creating a waterproof barrier that seals in the small cracks.

Aside from extending the life of your asphalt and protecting it from weather damage, a sealcoat also boosts your property’s curb appeal. The dark color of the seal coat will make your asphalt look new and well-maintained. The uniform black surface is also easy to keep clean, making it a good choice for people who regularly use the space for work that leaves debris behind.

If you are considering having your pavement sealed, it is important to know that the process is not a quick fix. It takes time to prepare the area and allow the asphalt to dry, so you should plan accordingly. Before the work begins, you should block off your driveway or parking lot and make sure that nothing can get into the work area. If your driveway or parking lot has an automated sprinkler system, it should be shut off completely during the process.
