ASPHALT and FABRIC OVERLAYS As asphalt paving is exposed to traffic and irrigation, its surface becomes rough and develops fine cracks, but is otherwise in good condition. In this case an Asphalt Overlay is a cost-effective solution which adds years of use to the existing pavement. An Asphalt Overlay consists of installing an additional layer (minimum 1” up to 2”) of new hot mix asphalt over the old, deteriorated surface. In some cases, when the surface cracks are severe, a Fabric Overlay is the best solution. A Fabric Overlay is similar to an Asphalt Overlay, but adds crack-retarding fabric between the layers of the old and new asphalt. This “bridges” the cracks delaying the appearance of new cracks, extending your budget dollars. ASPHALT REPLACEMENT In the last stages of its life-cycle, asphalt will begin to crack allowing water to destabilize the base rock and soil under it, creating potholes and “alligatored” areas (severe and dense cracking). At his stage, the area(s) of failed asphalt must be removed. Once removed, the base rock and soil underneath are re-compacted and new hot mix asphalt is installed and compacted flush to the adjacent paving.
