Techniques For Pavement Rehabilitation Course

Course Description

This course covers the essential elements of mechanistic pavement analysis and design, with an emphasis on the implementation of concepts in practical design situations. After completion of the course, candidates should be updated with the latest technology in the field of pavement design.

Course Objective

The course addresses all aspects of asphalt technology, successfully implemented roadway pavement structural design, hot mix design, maintenance and rehabilitation. The course details Superpave system for selecting materials and designing asphalt mixtures to meet climate and traffic conditions of specific roadway paving projects. Also it highlights the pavement management system and asset management. The course provides tremendous exposure to the North American experience and technology for all sectors involved in design, construction and quality control.
