The bitumen softening Point Test is done to determine the consistency of bitumen. Bitumen is a viscoelastic material, which means it behaves like both a liquid and a solid state. It does not have a specific melting point. As the temperature increases, the bitumen becomes softer and the viscosity of the bitumen decreases. One of the common parameters for classifying bitumen is the softening point of the bitumen. This property shows at what temperature the bitumen softens. … Read More Bitumen Softening Point Test – Ring and ball method
The penetration test for bitumen is a laboratory method for grading bitumen based on its hardness. In this test, the amount of penetrating a specific needle into the bitumen is measured.
More than 85% of bitumen is used in road construction. Weather condition affects on bitumen binder. In cold weather, bitumen becomes hard, and the possibility of cracking increases. On the other hand, hot weather causes bitumen becomes soft and sticky.… Read More Penetration Test for Bitumen – Significance and Procedure

A cloverleaf interchange is a two-level interchange at which left turns are done by ramp roads (reverse directions in left-driving regions) (US: ramps, UK: slip roads). Vehicles first proceed to go left (in right-hand traffic) as one lane crosses over or below the other, then exit right onto a one-way three-fourth loop ramp (270 °) … Read More Cloverleaf interchange- Examples and Problems
