AN EVALUATION OF THE CURRENT CALIFORNIA METHOD TO DETERMINE AC OVERLAY THICKNESS

An evaluation was made of the present overlay design method (Test Method No. Calif. 356) by investigating projects that had been in place for ten years or failed prior to the planned ten year design life. The investigation consisted of a search of office files and field condition surveys. The findings of this study support the deflection analysis method of overlay design that was implemented by the Transportation Laboratory in 1969. (FHWA)
