Learning Objectives

This course aims to provide students with knowledge and skills related to asphalt materials and pavement design and maintenance, including choice of materials and characterization, mix concrete design, paving asphalt levels using both empirical and mechanistic methods, performance evaluation of existing sidewalks, by visual inspection, manual system, high-speed equipment and instrumented vehicles and laboratory tests of materials. It is designed for highway-related engineers and managers or anyone wishing to deepen their knowledge of asphalt materials, pavement design and maintenance.
