POTENTIAL USE OF TIRE RUBBER AND EBONITE IN ASPHALT. EXECUTIVE SUMMARY AND FINAL REPORT

This report evaluates effectiveness of rubber-asphalt and ebonite-asphalt mixes based on a review of published literature, and unpublished reports. It discusses in detail various aspects of these mixes, including: different applications, physical properties, experiences of state highway agencies, and claimed advantages and problems associated with their use. Although rubber-asphalt mixes have superior physical properties, they have performed either only slightly better or equal to conventional asphalt mixes in the field. The salient problems associated with rubber asphalt mixes which restrict their use are: stickiness, high cost, and air pollution. The cost of rubber-asphalt mixes is much higher than conventional asphalts, and there is little evidence that rubber-asphalt mixes will have an increased service life sufficient to justify the high costs. Ebonite-asphaltic mixes have possible applications assuming that the ebonite can be economically cleaned of lead contamination.
