Abstract:

This research studied thick-lift asphalt concrete construction using a tamper bar paver. Tamper bar pavers were deployed on three paving projects to place asphalt layers ranging from 6 to 10 inches thick. On each project, test sections were constructed in one and two lifts, evaluating different lift thicknesses, paver screed settings, and rolling patterns. The research team monitored the mat cooldown time; measured mat density throughout compaction; tested the mat after construction with a rolling density meter, 3D Radar, and an inertial roughness profiler; and sampled 172 cores for laboratory testing of air voids and air void uniformity.
