Performance of Two Rubber-Modified Asphalt-Concrete Overlays: A Three-Year Progress Report Author(s): VanBramer, Thomas F. Origin: New York Date: December, 1992 Categories: Performance Key Words: Tires, waste rubber, scrap rubber, rubber-modified asphalt concrete, construction, performance Summary: Reports on the three year performance of two test projects constructed with 0, 1, 2, and 3% CRM in the hot mix using the dry process and a PlusRide section. Rutting, cracking and raveling were recorded semi-annually. The mixes were tested for density, Marshall properties and resilient modulus. Surface friction was measured annually. Snowplow operators were surveyed to determine if there was any difference in show and ice removal for the different test sections.
