MAINTENANCE METHODS FOR CONTINUOUSLY REINFORCED CONCRETE PAVEMENTS

In late 1974, test maintenance sections were constructed on a section of I-65 south of Indianapolis, Indiana. The road was stratified into "similar" sections of pavement using deflection, cracking, and breakup as selection criteria. Various types of measures including concrete shoulders, undersealing, asphalt overlay, and installation of drains with various combinations of these methods were applied as a means for strengthening the pavements. In each case the pavement was patched prior to the installation of the maintenance technique. Since its construction, performance surveys have been made each spring and fall using deflection measurements, crack counts and a general condition survey of the test pavements. Soil samples that were obtained during the construction were tested and the soil and subbase characteristics were evaluated. A cost analysis was performed with a time frame of two years and an estimated cost for a third year of maintenance of the pavements. The overlay methods exhibited good behavior over the two years of service. The subdrains and concrete shoulder methods produced less than expected performance. /FHWA/
