Analysis and Design of Bituminous Pavements

ABOUT THE COURSE: More than 90% of the highway system in India are constructed with bituminous materials. This course will introduce the fundamentals of stress analysis procedures for bituminous pavements. Analysis of traffic, material characterization for design and distress, and aspects of reliability related to bituminous pavement design will be discussed thereafter. The students of this course will also get hands-on training on the use of IRC37 and understand the boundaries within which such design guidelines should be usedINTENDED AUDIENCE: 1.Graduate students in Transportation Engineering stream2.Practising Highway EngineersPREREQUISITES: This is a self-contained course for students and practitioners alike, and hence, no prerequisite is required. For those who do not have an undergraduate degree in civil engineering, familiarity with the construction of bituminous pavements will be helpful.INDUSTRY SUPPORT: Engineering Staff working in State and Central Highways Departments and PWD, Ministry of Road Transport and Highways, and National Highways Authority of India.
