Abstract:

This study investigated the applicability of two performance grade (PG) binders: PG 64-28+ and PG 76-22+ in open graded friction course (OGFC) by comparing their performances to that of an existing PG 70-28+, which is the only binder currently being used in OGFC mixes in New Mexico. A goal of this study was to evaluate the effectiveness of New Mexico Department of Transportation (NMDOT)’s OGFC mix design, which is based on volumetric but not performance based. Considering the effects of aggregate gradation on OGFC performances, three different aggregate gradations (two 9.5 mm NMASs and one 12.5 mm NMAS) were employed in this study. A comprehensive laboratory experimental program was designed to investigate the drain-down, moisture damage, abrasion, aging, wet durability, and fracture performances of nine OGFC mixtures prepared with three binders and three aggregates. Based on the extensive analysis of the all the laboratory test results, it was found that PG 76-22+ OGFCs exhibits better performances than PG 70-28+ OGFCs.
