California’s Perspective on Concrete Pavement Preservation

The California Department of Transportation (Caltrans) has established a strong pavement preservation program to preserve existing pavements and delay rehabilitation. To implement this effort, Caltrans developed a 5-year pavement preservation plan with dedicated funding and established the Pavement Preservation Task Group (PPTG) consisting of over 22 subgroups, several of which apply to concrete pavement preservation specifically. The PPTG works as an advisory body to the California Pavement Preservation (CP2) Center located at the California State University in Chico. This paper describes the major pavement preservation activities underway on pavement preservation of concrete pavements in California. In particular, it covers the following activities: 1. The development of the Maintenance Technical Advisory Guide (MTAG – 1) for Rigid Pavement Preservation. 2. The performance of diamond-grinding projects and the benefits of diamond grinding in life extension, ride quality improvement, and noise reduction. 3. The performance of dowel bar retrofits and the lessons learned from several projects. 4. The performance of full-depth slab repair, particularly with regard to the use of rapid strength concrete (RSC). Caltrans plans for implementing pavement preservation on a more widespread basis within the State are also discussed, for both pavements in general and rigid pavements in particular.
