Product Description

GD-4508G-1 Bitumen Ductility Machine ASTM D6084 for Bitumen CRMB Elastic Recovery Test


Definition:

Ductility is the ability of a material to undergo a visible enduring deformation through elongation (decreasing of cross section area). It expresses the extent to which the material can be plastically deformed without fracture. The opposite material behavior is brittleness. 

The test for elastic recovery is applicable to binders modified with elastomers and serves to demonstrate the modification of the binder. The sample is stretched at a fixed temperature and speed to a maximum of 20 cm and then severed. After a prescribed period of time, the degree of elastic recovery is determined relative to the original length.
