Why Your Pavements Need Sealing
Pavement sealing and sealing are similar used words. 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. 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. There are factors which determine the period the sealing will last which include the traffic.
There are things which make the asphalt to crack. Common cracks includes the shrinkage cracks. These are caused by the lack of traffic. This cracking is also cause by extreme temperatures. Structural crack are also known as reflective cracks. They are caused by the vertical or the horizontal movements of the pavement beneath. The expansion and the contraction are as a result of the changes in the temperature and are what causes this to happen. These cracks after they occur need to be filed up. Crack filling comes in here. Cracks in the asphalt allow water to penetrate through. Softening of the stone base is done.
Potholes and webbing of the spider form on the crack with time. This happens when they are left unfiled and they allow rain and moisture to flow through. 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. Vegetation growth in the cracks is prevented by filling. As the vegetation roots grows bigger, it pushes the pavement surface up. More damage is created by this. Other problems rise up and the pavement breaks.
Crack filling job is not difficult. It is easy to repair a simple crack. These simple cracks occurs as the ground moves and also as the pavement ages. To repair the crack you will need to dig down and completely remove all the debris. Using the rubberized crack filler is therefore important to maintain your asphalt pavement.
Reduction of deterioration can be done by sealing the cracks. Prevention of water penetration in the underlying base and sub-base layers is what makes it possible. Filling the cracks with hot or with cold rubberized crack filler helps in preventing moisture inside. It is important to consider preventive maintenance. Your drive is thus made to last long. Installation of the sealcoat in the right manner protects asphalt from fuel, oil and weather.
Many benefits are affiliated to sealcoating. Reduction of your long term repair cost is done. Accelerating melting of snow and ice on the surface. This is very important especially for the countries that have a lot of ice in the winter season. Protection against water, rain and frost damage is ensured. Your pavement is prevented from oxidation, oil and chemical spills. Through sealcoating that is properly installed, the appearance of your compound and landscape is greatly improved.
