All pavements require maintenance. Preventive maintenance is less expensive, if early detection and repair of minor defects are taken care of before major corrective action is necessary.
Asphalt repairs are necessary within time as asphalt surfaces begin to wear and break down as they are repeatedly exposed to elements such as traffic wear and tear, water penetration, surface oxidation from the suns UV rays and oil and chemicals that drip from leaky vehicles. Surface breaks of any kind allow moisture to percolate below the surface, where it undermines the integrity of the pavement. The liquid asphalt that binds the materials together begins to lose its natural resistance to water, allowing it to penetrate beneath the surface damaging the base that supports it.
Once this occurs the asphalt pavement loses its elasticity and can quickly fall prey to a number of different types of deterioration including cracks and potholes.
