Reflective Cracking in Cement Stabilized Pavements

Cracking in asphalt pavements Cracks occur in flexible (asphalt) pavements for a wide variety of reasons. Some cracks are indicative of failure in the pavement, such as fatigue cracking, thermal cracking, or cracking due to base failure. Other cracks, such as reflective cracks in cement-sta-bilized pavement bases, are mainly cosmetic in nature ...

Joint Reflective Cracking (8)

Joint Reflective Cracking (8) Description. This distress occurs only on asphalt- surfaced pavements that have been laid over a PCC slab. It does not include reflection cracks from any other type of base, that is, cement- or lime-stabilized; these cracks are caused mainly by thermal- or moisture-induced movement of the PCC slab beneath the AC surface.

In short order, the constant movement causes reflective cracking of the asphaltic concrete overlay. This reflective cracking then leads to water infiltration at the joints and cracks and even weaker pavement support. The continual movement of the pavement causes spalling of the asphalt overlay and significantly reduces the life of the overlay.
