Tips on Maintaining Your Asphalt Pavement and Parking Lot Fundamentally,asphalt pavements are made by using a material called a binder to hold together tightly stones and gravel into a lasting durable state. The binder or Asphalt cement is made by a distillation process involving crude oils The pavement degradation process starts when the binder is exposed to the effects of chemicals,ultra violet rays of the sun or rain over time. Uncontrolled asphalt degradation results in pavement surfaces that appear unpleasant or in some cases they may look like they need a serious face lift. A program involving sealcoating or crack sealing should be embarked on in order to lengthen the life of your driveway or parking lot. Sealcoating provides a protective layer that keeps off the elements from coming into contact with the binder. It is certainly more cost effective to control potential degradation when the cracks are small rather than having to spend thousands of valuable dollars at latter times when entire payments have to be redone. Crack sealing looks simple but involves a lot more than what one may imagine. You need to buy the correct material to be used for filling up the cracks. The quality of a crack sealing process is determined by how well the asphalt surface to be repaired is prepared before the filling process commences.

A thorough sweeping of dirt from the area to be worked on using a bloom or a high-pressure compressor will ensure that all dirt and debris are removed before the material is applied,as presence of such dirt or debris weakens the power of the material to bond well with the cracked surface.

Compressors should properly be checked to so that they don’t blow moisture or oil droplets into the area under work. The crack fill should be applied immediately the crack is cleaned and dried up. The following few things should be borne in mind when doing sealcoating. Do not perform seal coating if there is any indication that rain may fall in the next 24 hours. Don’t ever do sealcoating under temperatures that are lower than 50 degrees. At least 2 coats should be applied if one wants to get satisfying results. The sealcoat should be let to cure for a minimum of 1 day before the pavement can be used again. As a general rule, sealcoating is applied every 2-3 years to prolong the life of the pavement. Generally,re-striping should happen when visibility of the paint has been reduced to about 75% or after 2 years. Always confirm that your parking lot is ADA(Americans with Disabilities Act)compliant before doing the lot marking. The proper application of these processes at the most appropriate time will help you keep your asphalt pavement looking great and well taken care of for long.
