Reasons to Seal Your Pavements
Pavement sealing is in other words referred to as sealcoating. A protective coating is applied to the asphalt based pavements in the process. Water, oils and the UV damage elements do not damage it due to the layer of protection offered. The life of the asphalt pavement is extended. 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. The span which the sealing lasts however depends on various factors such as traffic.
There are things which make the asphalt to crack. Shrinkage cracks are very common. Traffic lack is the cause of these cracks. This cracking is also cause by extreme temperatures. Reflective cracks are also called the structural cracks. What causes these types of cracks are the vertical or the horizontal movements of the pavement beneath. The changes in temperature changes cause the expansion and the contraction. After they occur, these cracks needs to be filled-up. Coming in of the crack filling is here. Water is allowed to [pass through the cracks in the asphalt. Softening of the stone base is done.
With time, this crack forms spider webbing and potholes. When rain and moisture is allowed to flow through and are left unfilled, that id what happens. Premature failure and potholes arise after the base material is eroded. The useful life of the surface is then shortened. The replacement of the surface later is costly. Filling of cracks prevents vegetation growth in them. Surfacing up of the pavement happens with the growth in the roots as they become bigger. More damage is created by this. Other problems rise up and the pavement breaks.
The job of crack filling is not difficult. A simple crack is easily repairable. 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. Asphalt movement can be maintained using the rubberized crack filler.
Reduction of deterioration can be done by sealing the cracks. Water penetration prevention is done in the underlying base and sub-base layers. Filling the cracks with hot or with cold rubberized crack filler helps in preventing moisture inside. Preventive maintenance consideration is very important. Your drive is thus made to last long. When the sealcoat is installed properly it protects asphalt from fuel, oil, weather and traffic wear.
There are many benefits of seal coating. It reduces the long term repair cost for your pavement. Melting of the ice and snow on the surface is accelerated. For the countries that have ice in the winter season this therefore is very important. Protection against water, rain and frost damage is ensured. Protection of your pavement from oxidation, oil and chemical spills is ensured. Proper installation of sealcoating makes the appearance of the compound and the landscape look better.
