Fourth Cycle of Pavement Research at the Pennsylvania Transportation Research Facility. Volume 7. Fourth Cycle of Pavement Rsearch Summary Report

摘要

The fourth cycle of research involved the evaluation of the structural behavior of a variety of bituminous and portland cement pavement materials, including open-graded subbase, cold recycled base, portland cement concrete, and three different wearing course materials (PaDOT ID-2A, ID-3, and FJ-1). The Skid Resistance Research Facility and a new Pavement Roughness Research Facility were constructed as part of the project, extending the calibration and research capabilities at the Facility.
