Asphalt Overlay - US Fabrics

An asphalt overlay geotextile, or paving fabric, is designed to hold asphaltic cement tack coat and withstand the extreme temperatures associated with paving. It functions by creating a moisture barrier between the old asphalt layer and the overlay, decreasing introduction of water into the base, reducing the effects of reflective cracking and ...

Field Evaluation of Engineering Fabrics for Asphalt ...

An asphalt concrete (ACC) overlay is most often the rehabilitative effort used to maintain the serviceability of either an ACC or PCC pavement. The major problem in durability of this ACC overlay comes from reflective cracking. These cracks usually open, allowing water to enter the unsealed crack and strip the ACC in the overlay. The stripping of the ACC allows accelerated deterioration at the ...
