Learn what causes asphalt to deteriorate.
While asphalt is known for its durability and strength, it still needs proper maintenance and can deteriorate over time. Properly laid asphalt can last a long time in your parking lot, but long-term exposure to the elements can cause damage faster than you may think. Continue reading to learn more about asphalt deterioration. (more…)
Check out these tips for property managers to budget needs for asphalt paving and repairs.

Learn more about the asphalt index and how it affects you.
Have you noticed that the price of asphalt changes frequently? This is because the cost of asphalt is dictated by the Asphalt Index, which changes every month. Maryland’s asphalt index is determined by The Maryland Asphalt Association, which updates its website every month with the new price. As of June 1, 2018, the Maryland asphalt index is $516.67.

Learn the differences between concrete and asphalt.
Concrete and asphalt are both great for parking lots, sidewalks, driveways, and more, but the materials have many differences. Continue reading to learn what separates concrete and asphalt, and if one material makes a better pavement than the other. (more…)
Tar and asphalt have a similar appearance and similar characteristics, but they are quite different materials. While they are both black, soften when heated, and harden when cooled, their performance properties are very different. Continue reading to learn more about the differences between asphalt and tar.
Asphalt is either in a solid or semi-solid consistency, depending on its temperature. It is a mixture made up of sands, grits, and stones (bitumens and aggregates.) Asphalt is produced in two different ways: natural asphalt and residual asphalt. As its name suggests, natural asphalt is obtained from nature, especially from lakes and rocks. Lake asphalt contains 40 to 70 percent of pure bitumen, which is then boiled to evaporate the water content separate impurities. Rock asphalt only contains 10 to 15 percent of pure bitumen and calcareous matter. The process includes crushing and heating the rocks, then suddenly cooling them to create consolidated rock. Residual asphalt is obtained in the residue of petroleum refining.
Tar is either in a solid or high viscous liquid consistency and contains a high amount of carbon content. Three general forms of tar include coal tar, wood tar, and mineral tar. Coat tar is obtained during the production of coal gas and is used for things including preserving timber and laying macadam roads. Wood tar is obtained by the distillation of resinous timber, such as pine wood. This type of tar has a preservative property, so is suitable for preserving wood. The exploitation of kerogens produces mineral tar.
While asphalt and tar look similar, tar often has a blacker color than asphalt, which is categorized as more of a black-brown color. Asphalt is either in a solid or semi-solid state, while tar is in a liquid state. Asphalt has a low carbon content and high water resistance, while tar is the exact opposite. Tar also has high adhesive power and a long setting time, and asphalt has a low adhesive power and shorter setting time.

Damage to parking lots can be caused by the drop in temperature, resulting in cracks and potholes.
Winter has arrived in Maryland, bringing freezing temperatures, blustery winds, and icy precipitation, including sleet and snow. While it can be an exhilarating and invigorating time of year, the cold weather also presents special challenges for people who own businesses.

Did that know that road salt has many negative environmental effects?
Road salt is used throughout the country by municipalities and property management companies to keep roadways and parking lots safe. However, road salt is not always the best thing for the asphalt or pavement that it’s being placed on. Beyond how it affects the pavement itself, it’s also important to consider the environmental ramifications of road salt. (more…)
While asphalt is one of the most durable materials used in construction, it can also deteriorate over time from errors and improper maintenance.
As one of the most durable materials used in construction, asphalt adds dependability and strength to all paving and building projects. Aside from those factors, the result is also a sleek, professional look that will make people marvel. However, like any other material, over time asphalt will start to show signs of its age and exposure. Even asphalt that is well maintained will begin to deteriorate after some time, depending on its environment and how it’s used. Here are some reasons why asphalt deteriorates. (more…)
Sealcoating protects a parking lot and makes it look fresh, new, and clean.
Sealcoating a thin liquid layer added over a paved surface serves to protect it from damage caused by UV rays, rain and snow, and fluids from vehicles. Sealcoating won’t cure existing issues, like cracks, but it will help prevent such damage from forming in the first place. Aside from keeping out damaging elements, properly applying a sealcoat is important to extend the life of asphalt paving. Sealcoating protects and prolongs the life expectancy of asphalt pavement by filling surface damage and providing a protective layer to keep out damaging UV rays, vehicle fluids and water. (more…)
Sealcoating is a crucial set in proper asphalt maintenance.
Seal coating is a true barrier between asphalt surfaces and the destructive elements. The term “seal coating” means keeping the redeeming properties of asphalt sealed in to prolong the pavement life and preserve its functional properties. The primary reason to sealcoat an asphalt pavement is to protect the pavement from the deteriorating effects of sun and water. When asphalt pavement is exposed to sun, wind and water, the asphalt hardens, or oxidizes. This causes the pavement to become more brittle. As a result, the pavement will crack because it is unable to bend and flex when exposed to traffic and temperature changes. (more…)
