Installation Report: Rubber Modified Asphalt Mix

Report No: 84-R1

Published in 1983

About the report:

This report describes the design of an asphalt mix containing up to 3.0% closed cell waste rubber and a field installation of the mix. The Marshall design procedure was used to determine the asphalt content for the mix containing 3.0% rubber as well as that of a control mix which did not contain rubber. In the field installation, 211 tons of mix containing 1.5% or 3.0% rubber were laid on Route 460 in Bedford County. The only problem encountered was that the breakdown roller tended to pick up the mix until the temperature decreased to 225°F. Results of Marshall tests made on samples taken from the field mix are presented in the report.
