Bituminous materials exhibit a complex mechanical response, and an understanding of the same is paramount in pavement engineering. This course will include introductory elementary linear viscoelasticity, and use that framework to introduce different grading system for bitumen. Use of polymers to enhance the rhelogical properties will be discussed along with the various test methods to quantify such improvement. Mechanical characterization of bituminous mixtures for modulus determination for design purposes as well as quantification for laboratory performance in rutting and fatigue damage will be discussed.INTENDED AUDIENCE : 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 construction of bituminous pavements will be helpful.INDUSTRY SUPPORT : Engineering Staff working in Oil Refineries, Modified Bitumen Manufacturers, State, and Central Highways Departments and PWD, Ministry of Road Transport and Highways, and National Highways Authority of India.
