  • Abstract:
    This report provides a review of the performance and structural characteristic exhibited on five continuously reinforced concrete pavement projects in the State of Louisiana. The performance characteristics were evaluated by means of the Mays Ride Meter. The structural characteristics were determined by means of the Dynamic Deflection determination System (Dynaflect). Physical characteristics of cracking and deterioration were visually observed.

    In general the overall performance of CRCP appears to be as good as jointed concrete pavement, particularly from a deflection and smoothness standpoint. Detrimental deflection is generally acknowledged when Dynaflect deflection values exceed 0.75 milli-inches. The average deflection value is presently 0.63 milli-inches or less for each of the five CRCP projects. Early pavement deterioration experienced on several of the projects should be noted, however. For the most part this heavy deterioration is recent development within the past three years. The performance of CRCP from a deterioration standpoint is considered very unpredictable at this time.

    The Louisiana Department of Highways as of June, 1974, made the decision to utilize plain concrete pavement with 20-foot joint spacing in lieu of CRCP. The factors contributing to this decision were the non-availability and high price of steel.
