Past experience in Kentucky indicated that thickness designs using portland cement concrete best agreed with criterion used in the Portland Cement Association's design method for 2 or 3 million EAL's or less. For EAL's greater than 3 million, past experience best agreed with criterion developed from the AASHO Road Test. Research reported herein indicates the two criteria
