This report is one of a series of reports prepared as part of a recent study sponsored 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 FHWA study included the following: (1) Conduct of a literature review and preparation of an annotated bibliography on CRC pavements and CRC overlays; (2) Conduct of a field investigation and laboratory testing related to 23 existing inservice pavement sections 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; (3) Evaluation of the effectiveness of various maintenance and rehabilitation strategies for CRC pavements; and (4) Preparation of a Summary Report on the current state of the practice for CRC pavements. Each of these four items is addressed in a separate report. This report, Volume III in the series, presents the results related to the field investigations of selected CRC pavement sections. Also, a summary of data collected to date (1992) for the 83 GPS-5 test sections is presented.
