Sealcoating Your Asphalt Pavement

Sealcoating extends the life of asphalt pavement for minimal cost. It prevents oxidation, stops weather damage, and prevents unsightly and dangerous potholes from forming.Sealcoating

Refined coal tar is the crucial ingredient in most sealcoats. It binds the other elements together and gives the product its deep black color. The other ingredients help with drying time, altering sand suspension, improving flexibility, and resistance to salts and petrochemicals.

Seal coating can help asphalt look brand new, and it can fill in cracks or small holes. However, it doesn’t stop water from damaging pavement or prevent aging and oxidation of blacktop. Fortunately, there are ways to slow the damage and keep your asphalt looking great longer.

One of the most common mistakes DIYers make is not blocking off the area to be sealed. Workers need a clear path to the asphalt surface, so this step is vital. The surface also needs to be clean and dry so that the seal coat bonds properly with the asphalt. This means that blowers or brooms will need to be used to clear away debris like dirt, leaves, and other loose material.

Workers should then sweep the entire area to ensure that any remaining debris is removed. This is particularly important in areas that experience a lot of rain, as the surface must be completely dry before sealing can take place.

After the surface is clean and dry, workers will spray a thick layer of the sealer onto the surface. They will then spread it evenly using brushes and squeegees, which helps ensure that the material fills in any cracks or holes. Once the sealer has been applied, workers will let it dry for 24 hours before vehicles can drive on the surface.

The best way to avoid the pitfalls of DIY sealcoating is to hire a professional for the job. Professionals have years of experience and know how to prepare and apply a seal coat that will last. They can also save you money in the long run by avoiding expensive repairs and replacements. In fact, it is estimated that it costs 75% less to maintain a driveway or parking lot with a seal coat than it does to repair and replace asphalt. This is especially true if you regularly schedule seal coatings every few years. If you wait too long between applications, your sealcoat may start to deteriorate quickly and cost more in repairs. In addition, you may not get the same level of protection from UV rays and other environmental factors.


Asphalt pavement is essentially rock and stone, held together by a substance called “binder” (created from the distillation of certain crude oils). Sealcoating is important because it helps to protect the binder from degradation. Over time, water, UV rays and other elements begin to break down the binder, which leads to deterioration of the surface. Regularly scheduled sealcoating extends the life of the asphalt, which in turn saves money on repaving costs down the road.

The first step in preparing for the asphalt sealcoating process is to thoroughly clean the area. The pavement must be free of debris, dirt and oil stains to ensure that the coating will bond properly. Once the area is cleaned, it should be inspected for any needed repairs. Crack filling and patching are essential asphalt paving repair steps that should be completed before any sealcoating is applied.

After the repairs are complete, a chemical stripper is used to remove any oil or grease spots that may be present on the asphalt. Then, the paved surface is vacuumed to remove any remaining debris or dirt. Once the surface is dry, a primer compound is applied to the paved area to help the sealer adhere to the surface. Then, the asphalt sealer is applied in two applications using state-of-the-art spray application equipment. Any areas that require a little extra work, like the trim, are brushed by hand to minimize the risk of overspray onto sidewalks, curbs or buildings.

Once the two coats of sealer are applied and allowed to dry, the paved area will be ready for traffic. A layer of sealer creates a smooth, black surface that looks brand-new and improves the curb appeal of the property. In addition, a smooth, uncracked pavement is easier to keep clean and clear of debris.

Pavement that is regularly sealed can stay in good condition for up to double the lifespan of untreated asphalt, saving money on costly repaving down the road. The minor labor involved in applying a layer of sealer is well worth it to protect the asphalt investment and keep the property looking its best.


A specialized layer of liquid protects asphalt surfaces from the elements that cause it to become brittle. Water, UV rays, chemicals from motor oil and gasoline leaks, and vehicular traffic wear away at the binding agent in asphalt. The loss of the binder eventually causes cracks and surface holes to form. Seal coating keeps these elements out and stops them from deteriorating the asphalt further, which extends its life and prevents costly repairs.

Workers apply the seal coat using spray hoses, self-propelled squeegee machines, or by hand with brushes and squeegees. The sprayed material needs to be evenly distributed for best results. To do so, the workers need to sweep and blow off any loose debris before applying the seal coat. Once the application process is complete, workers need to block off the area where they have been working from any traffic or pedestrians. This will keep them safe and ensure that no one steps on the newly applied asphalt while it is still curing.

Once the pavement has been sealed, it will need to be allowed to dry for up to 24 hours before traffic is allowed back onto it. If striping for parking spaces is required, it can be done once the pavement has fully cured. It is also a good idea to remove any barricades that have been placed in the parking lot during the process and to take down any signs that may be standing on the paved surface.

It is important to note that sealcoating does not repair existing damage to the asphalt. It is intended to act as a protective layer and stop the deterioration that will otherwise result in potholes and void the warranty on your new asphalt. It is much more cost effective to regularly apply sealcoating than it is to have a section of your asphalt replaced completely. However, it is a good idea to have your asphalt repaired and sealed as soon as you see any signs of damage. This will limit the amount of time that it takes for the sealcoat to prevent further damage and save you money in the long run.


Asphalt pavements are made up of rock and/or stone and gravel, held together by a binder that is derived from the distillation of certain crude oil products. Over time, rain and UV rays degrade this binder, which causes the surface to deteriorate and eventually crack. The seal coat prevents this process by creating a tough, long-lasting protective layer. It also improves the appearance of the asphalt by restoring its dark, glossy black color.

A high-quality sealcoat will last up to 10 years, but it’s important to perform maintenance every year in order to get the most life from your asphalt pavement. When you hire a professional to complete this service, they will be able to recommend the best times of year to apply the sealant for your particular climate and conditions.

Before applying any type of sealcoat, the pavement must be thoroughly cleaned. This includes removing any oil stains with a chemical treatment, power washing the area, and broom sweeping all debris from the surface. Linear cracks should be filled with hot rubberized crack filler before sealcoating. Then, the asphalt surface should be broom swept again to ensure a smooth, even application of the sealant.

It’s recommended to have professionals perform this task, as they will be able to use specialized equipment and pressurized sprayers to ensure an even application. They will also be familiar with the product manufacturer’s individual instructions on application, which will save you time and frustration. If you decide to do the project yourself, make sure you have the proper safety gear, as coal tar emulsions can cause skin and lung damage.

The Benefits of Asphalt Paving

Asphalt is a durable, cost-efficient, and environmentally friendly material. It is also versatile. Smooth roads reduce vehicle wear and tear and extend the life of a roadway – saving taxpayer dollars.Asphalt Paving

Asphalt pavements are built with a multi-layer process that ensures longevity. A strong but flexible base prevents cracks in the bottom layer, and a solid middle layer is then added that can last decades without needing total reconstruction.

Asphalt pavements are designed to be resilient, and they have a high level of fatigue resistance. This is one of the primary reasons that asphalt is a great choice for road construction and parking lots. It is also a popular material for residential driveways. However, it is important to understand that asphalt is not a “one size fits all” product. The type of material used, the thickness of the layer, the compaction process, and other factors can greatly affect longevity. A good paving contractor will be familiar with these considerations and will be willing to share information about previous projects.

While asphalt is very durable, it can be damaged by weather conditions and poor maintenance practices. In addition, the soil underneath can affect the longevity of the asphalt. For example, if the ground is loose, it can cause the pavement to shift or crack. These issues can lead to premature failure and require expensive repairs. It is crucial to hire a professional who takes these factors into account and follows best practices during the construction process.

There are several factors that influence the fatigue life of an asphalt mixture, including its composition, its temperature, and the amount of load cycles it experiences. It is important to use the right mix for each job. In order to achieve optimum durability, the asphalt should be mixed and compacted correctly. This is why many states are now specifying higher density specifications for hot-mix asphalt.

Another factor that contributes to the lifespan of an asphalt mixture is its consistency. It is important that the asphalt be consistent throughout the entire mixture, from the binder to the base course. This will help to reduce rutting, which is caused by the uneven distribution of traffic and environmental loads.

While achieving consistency can be challenging, it is possible with proper equipment and trained staff. There are many tools that can be used to monitor the quality of the asphalt during production, including handheld spectroscopic devices and x-ray fluorescence. These tools can help to detect and correct issues before they impact the quality of the pavement.

Ease of Maintenance

Asphalt is a great material for paving because it is affordable and easy to maintain. While it does require consistent maintenance, such as crack filling and sealing services, it’s much less expensive than other paving materials like concrete. It’s also recyclable, so when it reaches the end of its lifespan it can be recycled and repurposed, reducing waste and conserving resources.

Asphalt consists of aggregate materials, such as crushed rock, sand, and gravel, mixed with a sticky black oil-based substance called bitumen. The ingredients are heated to over 300 degrees Fahrenheit to make them malleable, and then they’re laid down over a prepared base. When the asphalt cools, it becomes solid and firm. It is then grooved with a broom or smoothed with a roller to create the desired texture. Finally, the surface is striped with lane lines, crosswalks, and any other necessary markings.

The durability of asphalt is one of its most significant advantages, as it provides a strong foundation for a road or parking lot, and can withstand heavy traffic loads. It also has excellent water-managing qualities, directing the runoff away from gassy areas or rerouting it to other places where it can be better managed. In addition, it has skid resistance and a dark color that helps melt snow and ice, making driving safer for both pedestrians and vehicles.

However, all asphalt eventually degrades over time. This is because the binding elements of the bitumen wear out, and the aggregates lose their binders as they shed water. It’s important to maintain your asphalt with regular maintenance and repair any problems as soon as you notice them.

While asphalt does have some disadvantages, such as temperature sensitivity, it’s still more durable than other paving materials and offers a good return on investment. If you take care of your asphalt, it should last for years before it needs to be resurfaced.

As with any paving material, it’s best to work with a professional when you need to repair your driveway or parking lot. Finding a company that has a good reputation in your area is important to ensure that the quality of their work meets or exceeds your expectations.

Low Impact on the Environment

Asphalt is infinitely recyclable and doesn’t release any harmful gases into the atmosphere during production. Furthermore, it is an incredibly green surface material. The paving industry is committed to continuously improving the sustainability of their products and processes. This is why they use the latest technology to build roads with permeable surface materials, which are a good way to prevent runoffs and water pollution.

The paving industry also uses recycled asphalt and aggregates, which reduces the need for virgin materials. The USA, for example, is the biggest recycler of asphalt, reusing approximately 65 million tons every year. Additionally, they utilize other types of recycled materials such as blast furnace slag, tires, and asphalt roofing shingles.

As a result, asphalt is more environmentally friendly than concrete, which is a non-recyclable material. When properly designed, maintained and resurfaced, asphalt pavements are capable of lasting for decades without requiring complete reconstruction. This is because it is constructed using a thick base course for bearing the main load, an intermediate (binder) course, and a 30-40 mm wearing course. When it is time to resurface, the old asphalt is milled off and reused into a new layer.

Another benefit of asphalt paving is that it allows for the natural absorption and filtration of water. This helps to prevent surface runoffs, which are a major contributor to flooding and soil erosion. By allowing water to filter through, asphalt surfaces reduce the need for costly stormwater drainage systems and contribute to groundwater recharge.

Additionally, asphalt’s porous properties help to reduce blinding spray on wet roadways and improve visibility for drivers. As a result, they can decrease the number of accidents and deaths caused by wet road conditions.

Furthermore, asphalt roads are quieter than concrete or other surfaces, which reduces noise pollution in communities. This is important because road noise can lead to hearing loss and disrupt sleep patterns, which has a negative impact on the health of citizens. Additionally, smooth roads can significantly extend a vehicle’s lifespan, thus saving money in maintenance and repair costs.

Asphalt paving is also quick and easy to install, which saves time and money for contractors and government agencies. In addition, it is less likely to require curing, which can lead to delays in traffic flow and congestion. This is why many asphalt paving projects are done at night so that the roads can be open to traffic again the next day.


Asphalt is a very economical material to use when building roads, streets and driveways. The materials cost less than concrete, and the paving process is quicker, which means that traffic can be moved on to the new road sooner. Asphalt also offers a number of environmental benefits, including saving taxpayers money through recycling.

The asphalt industry has made significant efforts to reduce the amount of waste produced during paving operations. In fact, asphalt pavements are recycled at a rate of over 300 million tons per year! The recycling process is very effective, as asphalt is a very durable material and can be recycled again and again without losing its integrity. Additionally, the asphalt industry has developed techniques for “rubblizing” existing concrete pavements, which saves taxpayers even more money while creating a much more long-lasting and strong surface.

A great many factors go into the economics of asphalt paving, and it is important to have a solid understanding of all of the relevant considerations in order to make the best decision for your situation. Some important considerations include:

In addition, asphalt requires much less energy to produce than other paving materials. In fact, it is estimated that a typical asphalt road uses about 20% less energy than a comparable concrete road. This reduced demand for energy lowers the impact on the environment and helps to improve vehicle efficiency.

Another factor is the price of asphalt, which can fluctuate significantly. This can have a considerable impact on the overall cost of a project. It is therefore essential to understand the impact of price variations and to find ways to minimize them.

The elasticity of asphalt is very useful when it comes to dealing with the stresses and strains on bridge decks, as it can be designed to deal with rapid changes in temperature. This is particularly important in areas where freezing and thawing cycles are common, as asphalt can be made to withstand these conditions effectively. In addition, asphalt can be ‘tailor-made’ for each road by adding different components to the mix, depending on the specific needs of the area. For example, a thicker base course can be used to effectively distribute loads above unbound granular layers, while an intermediate (binder) course can help to reduce rutting.
