With RPD you can perform the verification procedures by empirical methods (as proposed by AASHTO in the document GUIDE FOR DESIGN OF PAVEMENT STRUCTURES) or by rational methods. Among the rational methods, the highest deflection is implemented (Ivanov) and Westergaard’s, designed to calculate deflections on multi-layer pavements.
