Bitumen Tests for the Design of Flexible Pavements

COURSE NO: C04-065
Bitumen Tests for the Design of Flexible Pavements
Course Highlights

This online engineering PDH course provides a detailed description on the types of tests to be performed on the bituminous surface layer when designing flexible pavements.


A highway pavement is a structure consisting of superimposed layers of processed materials above the natural soil subgrade, which primary function is to distribute the applied vehicle loads to the subgrade. Pavements provide a smooth and durable all-weather traveling surface that benefits a range of vehicles (cars, trucks, buses, bicycles) and users (commuters, commercial motor carriers, delivery and service providers, local users, leisure travelers).


Bitumen is a binding material extensively used in the construction of flexible pavements. The bitumen is viscous black or brown mixture of hydrocarbons obtained as a byproduct on refining crude petroleum. Bitumen is responsible for imparting quality and durability for flexible pavements and is necessary to confirm its quality before applications. This course focusses on the various laboratory tests and procedures performed on bitumen for ensuring the quality.


This 4 PDH online course is applicable to transportation and roadway engineers interested in learning about the various bitumen tests to be considered when selecting and designing flexible pavements.
