Fourth Cycle of Pavement Research at the Pennsylvania Transportation Research Facility. Volume 1. Construction and Operation of the Pavement Durability Research Facility

摘要

The report describes the construction that was done for the fourth cycle of pavement research at the Pennsylvania Transportation Research Facility. The existing pavement was removed to the subgrade and new test sections were installed. The test sections included cold-recycled base course, open-graded base course, and fine and coarse-graded wearing course mixtures. The test sections also included 21 portland cement concrete pavement slabs. The report describes the various materials that were used in the construction of the test pavements, the operation of the Pennsylvania Transportation Research Facility, trafficking activity at the facility, and the field testing program that was conducted as part of the research. The field testing included pavement condition surveys and measurements of roughness, rut depth, and deflection.
