CONTROL OF REFLECTION CRACKING BY USE OF A PAVEMENT REINFORCING MEMBRANE

The following report outlines the installation of Petromat in two test sections as part of a resurfacing contract on Highway 50. Petromat is a nonwoven polypropylene fabric, which when saturated in an asphalt binder, bonds to pavement layers and acts as a stress relieving membrance beneath new road surfaces. The purpose of the trials was to determine if reinforcing the overlay would assist in controlling reflection cracking. Monitoring of the test sections will be carried out over the next few months and continued for a year or two. Should the use of this fabric prove to be successful, reductions in future rehabilitiation costs, through reduced thicknesses of overlays and deferred resurfacing, could be realized.
