HOT-MIX PAVEMENT STABILITY PERFORMANCE VERSUS LABORATORY TEST RESULTS

The problem to be addressed by this study was to determine what characteristics of the Item 340 hot-mix material itself and its production, placement and service environments were significant in determining how well the hot-mix surface layer would function in the field. SDHPT districts were asked for submission of well and/or poorly performing candidate pavements from a rutting or shoving distress standpoint. In all, 18 separate locations or sites were included in this study. The following types of data were obtained from these sites: (1) doing visual evaluations and taking rut depths on the surface, (2) taking roadway cores for subsequent laboratory testing. Also a records search was made to determine pertinent facts affecting each roadway site from hot-mix design through production, laydown, compaction and service history of the roadway surface. In general, the more rutted pavements contained softer asphalts, lower air voids and more temperature susceptible asphalts. Indirect tensile strengths and Marshall stabilities tend to be lower for the more rutted pavements. The more rutted pavements tend to have grading curves with the higher humps avove the No. 30 sieve of the ASTM continuous grading curv. Hveem stability appears to be no indication of rutting as found in this study. (Author) study. (Author)
