Evaluate Effectiveness of PCCP (Portland Cement Concrete Pavement) Rehabilitation Techniques
The study involved various PCCP rehabilitation techniques to improve the rideability and structural integrity of the pavement system. During the study, pavement grinding, slab replacements, asphalt concrete (AC) over-lays, slab jacking, grout subsealing, joint and random crack sealants, and edge drains were evaluated. This resulted in specification changes and discontinuation of some techniques. The study resulted in a moratorium on grout subsealing, provided tentative guidelines for the installation of retrofit edge drains, and provided the basis for further research to determine design strategies for rehabilitating PCCP. The results of the construction evaluated research project 'Evaluate Void Detection and Grout Subsealing of PCCP on 06-Ker-5-RO.0/29.0, Contract No. 06-246004' (partially funded by the study), are presented in Appendix 2. No reliable procedure was identified using either deflection measurements or ground penetrating radar that would accurately locate voids beneath PCCP prior to subsealing.
