Asphalt-Crumb Rubber Waterproofing Membrane

No date on item. Authors' manuscript. / This report is concerned with laboratory testing and field investigations of a water seepage barrier consisting of asphalt cement and
reclaimed crumb-rubber tire peel. The test methods that were utilized and evaluated included the following: water vapor transmission (ASTM E96 -72, Procedure BW), water absorption (ASTM 570-72), ductility (ASTM D113-74), viscosity, toughness, and brittleness /impact resistance (ASTM 0994-72). The test results showed that the asphalt-rubber as a membrane is relatively impermeable and absorbs an insignificant amount of water. The crumb rubber effectively increases the viscosity of the asphalt cement while decreasing the ductility value. The asphalt-rubber combination exhibits a tough, impact resistant membrane with excellent waterproofing properties.
