Construct Pavements With Help Of Asphalt Company Maryland Area

By Jaclyn Hurley


Having a properly installed asphaltic pavement by asphalt company Maryland area ensures that the structure lasts for many years. Depending on the construction standards applied by the contractor and the quality of material, you can have a durable driveways and parking lot. In addition, the kind of preventive maintenance you apply on the structure determines how long it will last.

The asphaltic material is composed of rock particles or the aggregate stones, the asphalt cement, and sand. This mixture can last for an extended period when laid down properly. The right mixture and compaction has to be applied to get quality structure. Newly constructed asphalt will be flexible because it retains most of the lighter hydrocarbon oils, which form part of the DNA structure of the materials.

When you construct driveways in your home, you reduce dust and mud from getting into your home. You also prevent the damages caused by bumpy driveways on your vehicles. Moreover, driveways add aesthetic beauty and economic value to a property. If you want to sell a property, you will find that it will fetch higher dollar value if it has properly constructed and maintained driveways.

An asphalt material is composed of sand, rock particles or aggregate stones, and the asphalt cement that holds the materials together. This kind of cement material is flexible and durable. With a new asphalt material, it has greater flexibility and it expands and contracts evenly without undergoing a lot of structural stress.

The outer surface of asphaltic materials is vulnerable to effects of sunlight and water. The ultraviolet rays from sunlight increase the rate of oxidation meaning that the material dries up fast than intended. Usually, asphalt undergoes a natural oxidizing process that lasts its lifetime. This means that, if the process of oxidizing is accelerated, the material will age fast and fail prematurely.

Naturally, asphaltic material cures and dries slowly with time. In fact, it undergoes an oxidation process in the rest of its life. As the molecules seek for an equilibrium state, they shuffle and rearrange themselves. This process of oxidation happens in lifetime until it is complete, and this is when the life of the material ends.

When the oxidizing process is over, you have reached the end of life with the driveway or parking lot. You have to construct another one. This may take more than thirty years depending on how you have been taking care of your driveways. The newly constructed asphaltic pavements have to be coated. The coating should only be applied when the blacktop has cured properly.

You will need about 6 to 12 months before the new blacktop cures properly to allow for seal coating. If you apply a seal coat too quickly, the surface will be too flexible, and it may form highly visible marks over time. When paving the driveways, you need to put at least two coats of quality sealer and the process is repeated after every 2 to 5 years. If you take good care of your asphaltic pavement, it will definitely add character to your home or business.
