Surface cracks are often the first visible signs of underlying problems with asphalt. Small cracks expand to form larger problem areas that have an “alligatored” appearance. Once this type of deterioration occurs, it is usually necessary to dig out the bad asphalt and install new sub-base and asphalt. Look for long cracks to appear where the seams were during initial construction. These are the weakest areas in the asphalt mat. Cracks in asphalt should be filled as soon as possible to avoid water infiltration and expansion. There are many types of crack fillers on the market, but Buckeye Asphalt Maintenance & Sealcoating, LLC will use a hot, pourable, rubberized, crack-fill material. It will have better results penetrating the crack and will be less likely to fail because of its capacity to expand and contract.
For residential driveways, we use a “trowel grade” crack filler. This is a thick, cold, crack filler that is applied and banded to ensure adhesion. Most of our residential clients prefer this crack filler to be used on their driveways because it has a smoother finish than the hot pour crack filler.
