Abstract
Reasonably and effectively determining the material grade is an important part of the design of the old road pavement structures in old road repair projects. Based on fuzzy logic and certainty theory, a novel South African pavement material classification system method was provided by adopting Design Equivalent Material Class (DEMAC). Starting from the discrimination principle, this paper elaborated on parameters such as the certainty factor, coefficient for sample size correction, relative certainty C(E), and relative confidence, and summarized and extracted the design process of a material classification system method based on South African standards. Case analysis shows that if experimental conditions permit, it is recommended to appropriately increase testing indicators to improve the certainty degree in determining DEMAC levels.
