Even though the AASHTO Design Guide is several years old, it is still used throughout the industry for pavement thickness design. The program used should be based on AASHTO design methods. The same parameters can be used for input data in computer programs on pavement determinations. This section will explain the parameters required to design the pavement thickness of both concrete and hot mix asphalt roadways. To design a pavement by the AASHTO method, a number of design parameters must be determined or assumed. General The AASHO road test (completed in the 1950s) and subsequent AASHTO Guide for the Design of Pavement Structures (AASHTO Design Guide) provide the basis for current pavement design practices.
