EFFORTS TO REDUCE REFLECTIVE CRACKING OF BITUMINOUS CONCRETE OVERLAYS OF PORTLAND CEMENT CONCRETE PAVEMENTS

Studies of efforts to reduce the incidence of reflection cracking when Portland cement concrete pavements or bases are overlayed with asphaltic concrete, revealed that neither sand as a bond breaker nor high strength fabrics as stress relieving layers are effective in reducing reflection cracking where vertical joint movement is a significant factor. Conclusions are also presented regarding the use of a high tensile fabric as a stress relieving layers between two asphaltic concrete overlays of an old Portland cement concrete pavement on a weak subbase, and the use of two types of fabric as stress relieving layers between asphaltic layers and a concrete base on a very strong subbase and subgrade.
