SIXTEENTH YEAR PROGRESS REPORT ON EXPERIMENTAL CONTINUOSLY REINFORCED CONCRETE PAVEMENT IN WALKER COUNTY

This report summarizes the findings of a 16-year study on an experimental CRCP placed on IH 45 in Walker County, Texas. An examination of data provides numerous guidelines for the design requirements and construction specifications of future projects where CRCP will be used. Specifically, substantially more failures were found with the lower percentage of reinforcing steel and higher curing temperatures. The data show Type 3 Cement gives higher steel stresses and that special attention should be given at all times to concrete vibration. The seven-year performance of a short section of a variable thickness asphalt-concrete overlay shows that the rate of failure and the deflection can be substantially reduced with an increase in overlay thickness.
