Reduction of Reflection Cracking in Bituminous Overlays on Rigid Pavements
This report describes attempts to control reflection cracking in bituminous overlays on rigid pavements. Three methods are discussed -- breaking the rigid pavement before overlaying, sawing joints in the overlay over those in the rigid pavement, and placing fiber-mesh mats over rigid pavement joints and cracks to dissipate local stress through the overlay. The results indicate that broken pavement and sawed joints are generally successful, but that mesh mats do very little to control reflection cracking. The feasibility and effectiveness of the three methods are compared.
