By Kerri Stout


Many business and homeowners use asphalt material in installing parking lots, lanes, and driveways because it is cost effective, long lasting, and environmentally friendly. It will cost you less to install pavements with this material. It also last for decades when it is fitted and maintained properly. Since the materials can be used in other pavement projects, it means that it contributes to conservation of resources. With help of asphalt paving Baltimore MD contractors, you are in a better position to lay down your pavements.

With good-looking pavements, they will improve the curb appeal and enhance the beauty of premises. They also help in easing traffic and reducing repairs and maintenance costs. Properly paved surfaces will also minimize the chances of accidents occurring. For the driveways, lanes, and car parking lots to last for long, qualified contractors who have the right equipment should install them properly.

Installing pavements is a long-term investment that should be protected. From the word go, a contractor should ensure all the stages of installation are done properly. Asphaltic driveways or parking lots use hot mix of asphalt that is carefully engineered. However, if the material is not laid down properly, it may unravel easily and wear out.

When the UV light bakes the outermost surface of pavements, it hardens the materials and cracks begin to form. Asphaltic material needs to be flexible so that it can contract and expand easily. Failure to this, it will crack and start allowing water to seep down. Both sunlight and water are the most destructive elements to asphaltic pavement surfaces.

When sunlight hardens the surfaces and cracks form, water finds it way inside the sub grade layer. The presence of water in sub base will cause other problems. The soils underneath pavements will become loose and the aggregate material will destabilize. This means it may not be able to support the heavy weight of vehicles.

Besides, water will freeze during the winter and widen the cracks. Freezing water expands and occupies more space. This leads to enlargement of cracks. After melting, the frozen water will leave empty spaces, which are eventually filled with material from blacktop. When the blacktop collapses and fills the empty voids, a pothole hole is created.

When it thaws, frozen water will leave empty spaces, which tend to fill up with the material from blacktop. That is why you find potholes forming on driveways after the winter season. Repairing potholes and other defects can be costly. To ensure your asphaltic paving surfaces do not suffer from such defects, inspect them properly and if there are any flaws, let them be handled immediately.

Once you have laid them, make sure you regularly carry out inspections to find out if they are working properly. Sealcoating is one thing you have to do time and again. Depending on how fast the blacktop is wearing out, you can carry out sealcoating in every 3 to 5 years. The first sealcoat is applied after the new asphaltic material has dried and cured completely. And, it takes about 6 months to one year for newly laid down asphaltic material to cure and dry. In addition, cracks should be repaired before they wreck havoc in pavements.
