Thickness Design Curves For Portland Cement Concrete Pavements, Herbert F. Southgate, Robert C. Deen
Thickness Design Curves For Portland Cement Concrete Pavements, Herbert F. Southgate, Robert C. Deen
Kentucky Transportation Center Research Report
Past experience indicates that thickness designs using portland cement concrete best agree with criterion used in the Portland Cement Association's design method for 18-kip EAL of 2 to 3 million or less. For EALs greater than 2 to 3 million, past experience best agrees with criterion developed from the AASHO Road Test. Research herein indicates the two criterion become asymptotic to each other at approximately 2.5 million EAL. For a variation in thickness and elastic moduli in portland cement concrete, dense-graded aggregate, and sub grade elastic modulus, research indicates that a general conic equation (included herein) very closely duplicates the …
