Structural Overlays for Pavement Rehabilitation
California's research on the use of deflection measurements for asphalt concrete overlay design has resulted in a revision to the California overlay design method. Deflection reduction characteristics and tolerable deflection levels of asphalt concrete were revised based on the performance of highway projects under study since 1960. An evaluation of the design method compares predicted versus measured deflections on 69 reconstructed highways. Pavement deflections were measured using a traveling deflectometer which provides a dynamic-type measurement while traveling along the roadway at one-half mile per hour. The results are discussed.
