With the objective of obtaining historical performance data for design, maintenance, and research, the Texas SDHPT initiated a series of condition surveys of CRCP in 1974. A follow-up survey was conduted in 1978. Using condition survey data for CRCP from 1974 and 1978 in the State, a qualitative analysis of the distress condition of these pavements was performed as described below. (1) The primary objective was to make a summary analysis of the 1978 condition survey data and compare it with the 1974 condition survey data. The results are presented in a summary form with only minimal statistical analysis; therefore, only the obvious observations or conclusions are emphasized. (2) The values predicted by the computer program, CRCP-2, are compared to the measured crack spacing data. The results indicate that the program is a viable tool that may be used to design the reinforcement for a given set of conditions. (3) In addition, preliminary criteria have been developed for major rehabilitation. Using discriminant analysis, an equation was obtained to weight the different distress manifestations and assign a score to each CRCP section. The magnitude of score is related to the distress condition of the pavement and can be used to decide if a pavement should be overlayed. (FHWA)
