Abstract:
Increased concern for the environment and spiraling prices for petroleum products have brought about an increased interest in the use of emulsified asphalts in highway construction. This emphasis has been primarily in the construction of chip seals using emulsions. In order to assess design and construction procedures, as well as roadway performance, an experimental emulsified asphalt seal coat was placed in Texas. The material selected for the chip seal was a CRS-2 emulsified asphalt with a design rate of emulsion at .35 - .40 gallons/square yard. The aggregate was Type B, Grade 4A, at a coverage rate of 1 cubic yard per 110-120 yard of surface. This report describes the construction procedures, material costs, energy consumption and savings, and performance of the section to date.
