Improvements of quality assurance testing program for subgrade and base layer construction

The performance of Portland Cement Concrete pavement depends on the support provided by layers under the concrete slab. Considering the importance of slab support on concrete pavement performance, a good quality assurance testing is needed for the construction of layers under the concrete slab. Deflection measurements on stabilized base could provide sound quality assurance testing. A threshold deflection value for construction acceptance was developed from the analysis of the field deflection data as well as theoretical analysis. Based on the information obtained, a protocol for quality assurance testing for base and subgrade construction was developed.
