![]() ![]() Chapter 6 provides some design examples using the 1993 AASHTO procedures. Geotechnical inputs to the 1993 AASHTO design procedure are detailed in Chapter 5. All versions of the AASHTO Design Guide are empirical design methods based on field performance data measured at the AASHO Road Test in 1958-60.Ĭhapter 3 of this manual describes the evolution of the various versions of the AASHTO Design Guide. Approximately 80% of all states use the AASHTO pavement design procedures, with the majority using the 1993 version. The AASHTO Guide for Design of Pavement Structures (AASHTO, 1993) is the primary document used to design new and rehabilitated highway pavements.
