Abstract:

A research project conducted by Oregon State University (OSU) and the Oregon Department of Transportation (ODOT) investigated compaction of Oregon F-mix asphalt pavement, an open-graded mix with 25-mm maximum size aggregate and air voids typically in the 17-26% range. The research sought to determine variations in compaction resulting from different compaction patterns, and accuracy of measurement of field densities to determine the feasibility of a density specification for F-mix. Nine different compaction patterns varying from 2 to 6 passes with minimum 7 Mg rollers and utilizing combinations of static and vibratory compaction were employed on six different overlay paving projects. Core densities were determined at five random locations on each control strip, resulting in 270 (5x6x9) core densities. Densities between compaction patterns were compared. Although the data indicate that introducing vibration and increasing the required number of passes from 4 to 6 would increase densities from those achieved with the current specification, the increase is relatively small and the effect on open-graded pavement performance is unknown. Prior to coring, field densities were determined by nuclear density measurement and through measurements with the Pavement Quality Indicator (PQI), a measuring device being developed by Trans Tech Systems Inc. and the Federal Highway Administration. Data obtained in this study did not show good correlations between measurements with either device and core densities. 59 p.
