Lecture
This lecture covers the properties and types of bitumen, including the diagram of Colombo, standard bitumen values, and the complex modulus. It also discusses bitumen modifications, such as emulsions and cutbacks, and the importance of porous asphalt for noise reduction. The lecture delves into the composition of bituminous mixtures, the role of aggregates and binders, and the optimization process. Additionally, it explores the impact of traffic, climate, and material aging on road performance, emphasizing the need for structural integrity, functionality, and environmental considerations in pavement design.
