Reasons to Seal Your Pavements
Pavement sealing and sealing are similar used words. Asphalt-based pavements are coated with a protective coating which is applied to it. It provides a layer of protection from the elements of water, oils as well as U.V. damage. There is extension of the life of the pavement. It also helps in the reduction of friction which is commonly associated with the pavement of asphalt. Your pavements on a normal condition will require sealing after every three-five years. Different factors such as traffic are what determines the span in which the sealing will last.
There are things which make the asphalt to crack. Shrinkage cracks are very common. These are caused by the lack of traffic. This cracking is also cause by extreme temperatures. Structural crack are also known as reflective cracks. Vertical or the horizontal movements of the pavement beneath are what causes these cracks. This happens due to the expansion or the contraction due to changes in the temperature. After they occur, these cracks needs to be filled-up. This is where crack filling comes in. Cracks in the asphalt allow water to penetrate through. The stone base is with time softened.
What forms on the cracks with time is the spider webbing and potholes. When they are left unfilled and rain and moisture gets in, that is what happens. The base material are then eroded resulting to premature failure and potholes. The useful life of the surface is then shortened. Surface later becomes very expensive in replacement. Cracks filling is important to prevent vegetation growth. Surfacing up of the pavement happens with the growth in the roots as they become bigger. This create more damage. The pavement breaks up and other problems.
Crack filling is not a difficult job. Repairing of a simple crack is easy. These simple cracks occurs as the ground moves and also as the pavement ages. You will need to dig deep and remove all debris before you repair the crack. Using the rubberized crack filler is therefore important to maintain your asphalt pavement.
Crack sealing of the pavement can reduce the deterioration. Prevention of water penetration in the underlying base and sub-base layers is what makes it possible. Rubberized crack filler either hot or cold prevent moisture inside when filling the cracks. Preventive maintenance is very important in consideration. The investment of your drive way can then last longer. Installation of the sealcoat in the right manner protects asphalt from fuel, oil and weather.
Many benefits are affiliated to sealcoating. It reduces the long term repair cost for your pavement. Accelerating melting of snow and ice on the surface. For the countries that have ice in the winter season this therefore is very important. Protection against water, rain and frost damage is ensured. Your pavement is prevented from oxidation, oil and chemical spills. Proper installation of sealcoating makes the appearance of the compound and the landscape look better.
