| 摘要： | The project examines differences between the construction and anticipated performance of a second generation asphalt overlay on jointed concrete pavement consisting of a two inch binder course with one and a half inch surface course following milling as opposed to PennDOT's standard treatment of milling followed by a maximum one inch leveling course and one and one half inch surface course. All asphalt materials meet PennDOT's Superpave requirements. A comparison was made between a 3.8 mile experimental section (with binder course) and a 5.8 control section (with leveling course). Project construction activities and fundamental material testing were conducted during the first phase of the project. Documentation was provided for field construction activities. Accelerated testing of the project materials was conducted to assess differences in the performance of the two sections with respect to fatigue and rutting. Pre- and post-construction surveys were conducted for pavement distress, deflection, and ride quality. / NOTE: Final rept.
