Performance of CRCP – Volume V: Maintenance and Repair of CRCP (FHWA-RD-98-101)
This report is one of a series of reports prepared as part of a National Pooled Funds study administered by the Federal Highway Administration (FHWA) aimed at updating the state-of-the art of the design, construction, maintenance, and rehabilitation of continuously reinforced concrete (CRC) pavements. The scope of work of the study included the following:
- Conduct a literature review and preparation of an annotated bibliography on CRC pavements and CRC overlays.
- Conduct a field investigation and laboratory testing related to 23 existing in-service pavement sections. This was done to evaluate the effect of various design features on CRC pavement performance, to identify any design or construction related problems, and to recommend procedures to improve CRC pavement technology.
- Evaluate the effectiveness of various maintenance and rehabilitation strategies for CRC pavements.
- Prepare a Summary Report on the current state of the practice for CRC pavements.
The following reports have been prepared under this study:
- Performance of Continuously Reinforced Concrete Pavements
- Volume I – Summary of Practice and Annotated Bibliography
- Volume II – Field Investigation of CRC Pavements
- Volume III – Analysis and Evaluation of Field Test Data
- Volume IV – Resurfacings for CRC Pavements
- Volume V – Maintenance and Rehabilitation of CRC Pavements
- Volume VI – CRC Pavement Design, Construction, and Performance
- Volume VII – Summary
This report is volume V in the series and presents the results related to CRC pavement distress and procedures for repair of CRC pavements. Because the most troublesome problems with CRC pavements are punchout distresses and distresses associated with steel rupture, more emphasis is placed on repairs of these distresses.
