Hot Mix Asphalt-Rubber Application in Virginia Author(s): Maupin, G.W., Jr. Origin: Virginia Date: January, 1996 Categories: Performance Key Words: asphalt rubber mix, pavement, and tire recycling Summary: Four test sections using asphalt rubber hot mix were places in Virginia during the period of 1990 through 1993. The purpose of these installations was to familiarize both contractors and Virginia DOT personnel with the construction process and compare the performance of different types of mixes containing ground tire rubber. The asphalt rubber mixes have performed as well as the conventional mixes over the short term. More evaluation time is needed to determine if the long-term performance of the asphalt rubber mixes is superior to that of the conventional mixes. The cost of the asphalt rubber mixes was 64 to 102 percent more than that of the conventional mixes, however, this cost would probably decrease if substantial quantities were placed.
