Reflective cracking in pavements occurs where cracks in older, underlying asphalt or concrete layers propagate up through newer overlays. Reflective cracking in asphalt-pavement overlays is typically caused by traffic loading, age hardening, or temperature cycling. When such cracking is present, the traditional remedy has been to apply thicker asphalt-concrete overlays to delay the reappearance of the cracks. In general, for each inch of overlay, existing reflective cracks are deterred from reaching the surface for 1 to 2 years.
