The detailed syllabus for Pavement Material Characterization M.Tech 2017-2018 (R17) first year first sem is as follows.
M.Tech. I Year I Sem.
Course Objectives: The main objective of this course is to provide students with a thorough understanding of the important factors in pavement design and analysis. The focus will be on practices of pavement desig and maintenance used by highway agencies.
Course Outcomes: At the end of the course, students will be able to
- Determine the proportions of ingredients required for the mix design of both asphalt mixtures and cement concrete.
- Characterize the pavement materials including soil, aggregate, asphalt, cement, asphalt mixtures, cement concrete.
- Select appropriate asphalt binder for construction of a flexible pavement depending upon the traffic and climatic conditions.
- Choose appropriate stabilization technique for pavement
