Title: Pavement Design Practice in India and Comparison with other Guidelines, with Special Reference to U.S. Practice.
Presenter: Dr. Animesh Das
Abstract: The current practice of structural design of bituminous and concrete pavements in India will be discussed in this seminar. The evolution of the pavement design approach - from empirical (1970) to mechanistic-empirical (2001) will be discussed briefly. The principles adopted for development of the design equations involving bottom up fatigue cracking, top down cracking and rutting will be discussed. The incorporation of cumulative damage principle for load stress as well as thermal stress (for concrete pavement) and the interplay between mix design and pavement design (for bituminous pavement) will be critically examined. The design considerations for special purpose pavements including bituminous pavement with cemented base or sub-base, perpetual pavement, stage construction, and pavements with emerging materials will be highlighted. Comparisons will made with the contemporary design practice followed in other countries, specifically the United States. Finally, some research challenges in the area of pavement design will be identified.
