Alternatives for the Optimization of Aggregate and Pavement Properties Related to Friction and Wear Resistance - Executive Summary

Abstract

DOT-FH-11-8814This report summarizes the major findings of a detailed, comprehensive report which has received only a limited distribution. The full report, FHWA-RD-78-209, is available upon request. An interdisciplinary team of researchers has conducted an in-depth review of the literature, supplemented with expert opinions, research experience, and limited tests, to develop a state-of-the-art on the topics of (a) properties of aggregates, (b) pavement texture and skid resistance, (c) tire-pavement noise, (d) tire wear, (e) light reflection and glare, (f) splash and spray, (g) rolling resistance and fuel consumption, and (h) optimal aggregates and pavement surfacing systems. A cost-benefit analysis is also summarized. The information on aggregates and their contribution to pavement texture, coarse and fine, is being used in on-going FHWA staff and contract research studies to investigate currently and potentially available ceramic and impregnation materials and processes for the manufacture or treatment of aggregates to provide extremely durable and skid-resistant pavement surfaces
