ASPHALT TESTING LABORATORY DUCTILITY TEST OF BITUMINOUS MATERIALS OBJECTIVES: To obtain the ductility value of bituminous sample. THEORY: The ductility test is measure of cohesiveness and elasticity of the bitumen. Bitumen is binder of pavement construction, which binds from ductility thin films around the aggregates.

Humboldt's ductility testing machines measure the distance of elongation before reaching the breaking point of a sample being pulled apart at a specific speed and temperature. This determines the ductility of formed asphalt/cement or semi-solid bitumen. Humboldt provides high quality, USA-made ductility machines and all the necessary ...

Asphalt cement grade of bitumen is one of the main categories of viscosity grade bitumen.The American Association of State Highway Official (AASHTO) has classified viscosity grade bitumen into two categories as follow.. First one is AC, which stands for Asphalt Cement, and the second one is AR, which is the abbreviated form of Aged Residue.

1.1 This test method describes the procedure for determining the ductility of an asphalt material measured by the distance to which it will elongate before breaking when two ends of a briquet specimen of the material, of the form described in 4.1, are pulled apart at a specified speed and at a specified temperature.Unless otherwise specified, the test shall be made at a temperature of 25 ± 0 ...

The consistency of asphalt cement from this process can be controlled by the amount of heavy gas oil removed. Normally, asphalt produced by this process is softer. As the asphalt cools down to room temperature, it becomes a semi solid viscous material. ... Ductility is the property of bitumen that permits it to undergo great deformation or ...
