Introduction For civil and transportation engineers, pavement design is not just a calculation—it is a commitment to public safety, longevity, and economic efficiency. The American Association of State Highway and Transportation Officials (AASHTO) has provided the backbone for pavement design methodology for decades, evolving from the 1972 Interim Guide to the widely adopted 1993 AASHTO Guide for Design of Pavement Structures.
