Abstract

Pavement performance depends on the quality of the material, the mix design, and construction. The objectives of pavement construction are to place the material with a smooth surface, and compacted to the target density. Inadequate density permits water to enter the pavement leading to premature distress. It also can contribute to rutting as the pavement densify. A surface that is too dense is also prone to rutting.;This research evaluated methods for: measuring density, quality control, and longitudinal joint construction. Density specifications for West Virginia and surrounding states were reviewed to assess the compaction requirements for hot mix asphalt (HMA).;This research proposes several changes to West Virginia's construction specifications, including the use of the nuclear gauge and a minimum density requirement for longitudinal joint. Some state-of-the-art construction techniques are presented to aid the contractor in obtaining the target density. Recommendations are also made for further research.
