Title: MINERALOGY OF AGGREGATES IN RELATION TO THE FRICTIONAL PERFORMANCE OF SEAL COAT PAVEMENT OVERLAYS: A PETROGRAPHIC STUDY

Availability: Find a library where document is available Abstract: A petrographic study was conducted to identify the mineralogical and textural properties of aggregates that may influence the frictional performance of seal coat pavement overlays constructed with these aggregates. Twenty aggregate samples were petrographically examined, and their performance in seal coat overlays was monitored over about 4 years. The petrographic and field results were used to formulate a probabilistic prediction model describing field performance. Statistically significant petrographic variables included the percentage of grain-supported texture particles, the amounts of dolomitic and other carbonate grains in aggregate particles, the percentage of noncarbonate matrix in particles, and the level of prevailing void content. A construction-related variable, the design spreading rate of aggregate particles, also showed significance in explaining some of the observed variation in frictional performance.
