Abstract

This unique approach for installing strain gages in PCC pavement sections in the Ohio SHRP Test Road was very successful. All sensors were installed during construction with no delays to the contractor, and all gages performed well in controlled vehicle tests which followed. After two and one-half years, more than 90% of the gages continue to balance electronically and function properly. Data from these sensors are expected to provide engineers with an in-depth understanding of how PCC pavements respond to traffic loads and environmental factors.
