Partial-depth repair (PDR) is a concrete pavement restoration technique that corrects localized distress such as spalls, scaling, and popouts in concrete pavements. PDR restores structural integrity and utility of the pavement, and prevents further deterioration, thus extending the pavements service life. Also, partial depth repairs are required to prepare an existing, distressed pavement prior to a structural overlay or restoration project.
PDR involves removing an area of deteriorated concrete that is limited to the top one-third of the slab thickness and replacing it with appropriate repair materials. Depending on the type of repair material used and the repair location, a new joint sealant system may be placed as well. The repair technique can be applied either transversely or longitudinally on the pavement where deteriorations are detected. When applied at appropriate locations, PDR can be more cost effective than full-depth repair. The cost of PDR is largely dependent upon the size, number, and location of repair areas, as well as the materials used. Lane closure time and traffic volume also affect production rates and costs.
This course is intended for civil engineers who are interested in restoration methods for pavements, particularly Portland cement concrete (PCC).
