Ductility of bitumen
WebIntroduction A test for One of the key tests carried out during the construction of roads is the bitumen's ductility. The ability of a material to undergo plastic deformation (permanent deformation) prior to rupturing (breaking) is referred to as ductility. Bituminous materials used in pavement construction should have sufficient ductility in order to prevent cracks … WebJul 23, 2024 · As long as the bitumen has good ductility, it will be resistant to road traffic as well as expansion and contraction of bitumen due to temperature changes, and the possibility of asphalt cracking will decrease and asphalt life will increase. To measure this property, bitumen is poured into a special mold and the mold is pulled from both sides ...
