HEAVY DUTY MEMBRANES FOR THE REDUCTION OF REFLECTIVE CRACKING IN BITUMINOUS CONCRETE OVERLAYS. FINAL REPORT

The prevalence of reflective cracking in asphaltic concrete overlays is a major factor contributing to the premature failure of the pavement system. This reflective cracking is caused by cyclic stresses induced in the overlay by movements in the underlying pavement. Recent work done with heavy-duty membranes has shown that they may be useful in retarding this reflective crack formation. Seven different types of heavy-duty membranes were placed over Portland Cement Concrete pavement joints at one site in Pennsylvania before the roadway was overlayed with asphaltic concrete. Control sections, without any membranes, wre also built into the project for comparison purposes. This work evaluated the ability of these membranes to reduce the occurence of reflective cracking over transverse and longitudinal joints and to function as a waterstop once cracking has occurred.
