Installation Report: Experimental Mix Using Foamed Asphalt

Report No: 82-R29

Published in 1982

About the report:

This report describes the first foam asphalt mix produced and used in a highway pavement in Virginia. The aggregate used was a local Eastern Shore sand modified with 5% fly ash to improve the gradation. A foam asphalt chamber on a portable pug-mixer was used to produce slightly more than 500 tons of mix. While the early performance of the pavement overlaid with the foam asphalt mix has not been too favorable, the project will be watched closely into the spring before determining whether to continue with the experiments.
