Answer (1 of 3): It represents softness or hardness of bitumen (completely melted form of bitumen, just like liquid) by measuring the depth in 1/10th of mm to which a standard needle carrying a weight of 100gms penetrates in 5 seconds at a temperature of 25 degree Celsius. If grade of bitumen is...

Bitumen Penetration Grades. The bitumen penetration test is a useful way of grading bitumen for better application. This test leads to the classification of bitumen based on the level of stiffness. Various bitumen pen grades are 40/50, 60/70, 80/100, and 85/100.

The Superpave binder specifications are performance-based; therefore, these binders are known as performance-graded (PG) binders in contrast to the older system of viscosity graded (AC) binders, which are typically used for surface treatments and aggregate precoating (see Item 300). Generally speaking, any paving mix produced hot through a hot ...

15 "pen" bitumen is the hardest and 450 pen bitumen the softest. In the construction industry, the term "penetration grade bitumen" is often abbreviated to "pen bitumen" or simply "pen bit". Penetration grade bitumen forms the basis of other road binders such as cutbacks, emulsions, and polymer-modified binders, which are all discussed below.

Two horizontal disks of bitumen, cast in shouldered brass rings, are heated at a controlled rate in a liquid bath while each supports a steel ball. The softening point is reported as the mean of the temperatures at which the two disks soften enough to allow each ball, enveloped in bitumen, to fall a distance of 25 mm. PROCEDURE (Figure 1) 1.

Ductility Test of Bitumen-Definition, Procedure & Determination Methods. Ductility test of bitumen is one of the main testes that you need to do during road construction. We know that the ductility of a material is the ability of that material to undergo plastic deformation (permanent deformation) before the rupturing (breaking) of that material.
