Course Pavements Highways

This course is an introduction to the definition of highways, the history of development and role of highways, highway classification, highway cross-sections. Highway pavement layer materials: asphalt, aggregate, filler. Types of asphalt and technology, asphalt properties, asphalt production process, asphalt classification, asphalt inspection, asphalt specifications, asphalt selection and mixing, implementation of the mixture in the field and spreading. Aggregate as a hard layer material: types of aggregate, aggregate inspection, aggregate specifications, analytical/graphical mixing of aggregates. Types of road pavement. Factors influencing road pavement planning. Stresses in flexible and rigid pavement layers. Subgrade bearing capacity: CBR, subgrade reaction modulus (k), subgrade stiffness modulus (E), design CBR, correlation between CBR, k and E, DDT. Carrying capacity of each hard layer. Relative strength coefficient. Planned traffic load. Regional factors. Flexible pavement planning using the Bina Marga method (Component Analysis Method), Overlay planning and gradual layer construction, rigid pavement planning using the Bina Marga Method, Road damage and road maintenance. Learning is carried out by applying a constructivist approach. The learning activity ends with an exercise in planning the thickness of highway pavement.
