Filling the cracks in your pavement is a vital step in your asphalt maintenance program. Doing so, prevents costly repairs. Cracks that are left open allow moisture to easily penetrate and deteriorate the asphalt. Water expands when it freezes making cracks in pavement larger. Standing water in cracks also worsens their condition; when vehicles drive over the areas where the water is held up in the cracks, the pressure from the weight of the vehicle forces the standing water deeper into the cracks ultimately cracking the pavement more. Keeping water out of the cracked asphalt is the key to extending the life of the asphalt. Properly applied hot rubberized crack fill will keep the water out. To avoid the cracks from re-opening, It is important to use road grade crack fill products that are engineered for our climate and install them according to the manufacture specifications.
