AAPT/ISAP International Forum: Twelve Years of Mechanistic-Empirical Pavement Design in India

In this paper, the authors discuss the evolution of mechanistic-empirical-flexible pavement design over the last twelve years in India. The first empirical design guidelines were published in 1970 by the Indian Roads Congress (IRC), followed by a 1984 revision that emphasized having a unified approach for flexible pavement design and considered axle load characteristics and lateral placement characteristics of commercial vehicles. Subsequent research resulted in additional revisions to the IRC's guidelines, focusing on such features as bituminous overlay design, flexible pavement failures, and bottom-up cracking. The authors highlight the significant developments that address pavement concerns and industry demands that have taken place in India over the years; however, they suggest that performance data, which is currently scanty, should be collected in a more systematic way that can enhance current performance and design models.
