Strength and Failure of Bituminous Pavement Materials

Structure of Bituminous Pavements Flexible road structure is a combination of several layers, which serves the purpose of distributing the loads from the traffic (both dynamic and static) to the underlying layers in a level so that the layers can bear ...

Types of Bitumen Emulsion-Uses, Advantages and Manufacture

What is Bitumen Emulsion? Bitumen emulsion is a mixture of fine droplets of bitumen and water. But as the bitumen is a petroleum product it doesn’t mix with water and as it is sticky in nature, it doesn’t easily gets disintegrated ...

Grading of Bitumen- Different Methods of Bitumen Grading

There are different methods of grading of bitumen such as chewing, penetration grading, viscosity grading and superpave performance grading of bitumen which are discussed in this article. History of Bitumen Grading The correlation between the bitumen stiffness and temperature varies with the ...

Viscosity of Bituminous Materials – Measurements and Factors

Introduction to Viscosity and Rheology of Bituminous Materials The resistance of a liquid in flowing is defined as the viscosity of that fluid. Under the action of force, the fluid reflects higher resistance when the viscosity is high. The two factors ...
