ActiveTest method for ductility of asphalt
沥青延度测定法
Application Summary AI generated
This standard specifies the method for measuring the ductility of asphalt by determining the distance a test specimen can be stretched before breaking under specified temperature and pulling rate conditions. It is applied in the petroleum and road construction industries for quality control and performance evaluation of both petroleum asphalt and modified asphalt used in pavement binders. The test is critical for assessing the material's flexibility and resistance to cracking in road surfaces and waterproofing applications.
