AbolishedStandard test method for ductility of bitumen
沥青延度测定法
Application Summary AI generated
This standard specifies the test method for measuring the ductility of bitumen by determining the distance a bitumen specimen can be elongated before breaking under specified conditions of temperature and pulling speed. It is primarily applied in the petroleum and road construction industries for quality control of paving asphalts and modified bitumens, ensuring materials meet performance requirements for flexibility and crack resistance. The test is commonly used in laboratory settings for raw material acceptance and formulation verification.
