Slab Replacement and Dowel Bar Retrofit

This report presents an evaluation of a project involving the rehabilitation of a 193.9-km long segment of Route 8 in San Diego County, California. The rehabilitation involves grinding the existing concrete pavement and installing replacement panels, and retrofitting dowel bars to restore load transfer. Cracking and distress had been observed in the replacement slabs and dowel bars, and this led to an investigation which focused on the observed distresses and installation procedures. The investigations revealed that panel replacements and dowel bar retrofit installations had not been constructed in conformance with the specifications. Recommendations were presented directed at filling in the cracks with epoxy, replacing concrete slabs and dowel bars, aligning foam boards, and applying sealant to transverse joints.
