Plain Cement Concrete Pavement on Cement-Treated Base

摘要

The purpose of the project was to evaluate the performance of plain cement concrete pavement on cement-treated base as compared to an equivalent structural design flexible pavement. Two sections of each type pavement were used in the study for a total of 3.5 miles of rural highway. The unreinforced concrete pavement was constructed, without dowel bars at transverse joints, in 1972-73. The road was opened to traffic in June 1973. The plain cement concrete continues to be in good condition after 15 years of use. Most of the defects can be attributed to construction problems or foundation factors. Plain cement concrete pavement standard drawings were issued in Pennsylvania in May 1979. Today the majority of all concrete paving jobs, regardless of traffic volume, are using plain cement concrete.
