"Thickness Design Procedure for Portland Cement Concrete ...

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
