ActiveTest method for breaking point of bitumen—Fraass method
石油沥青脆点测定法 弗拉斯法
Application Summary AI generated
This standard specifies the Fraass method for determining the breaking point of bitumen, which is the temperature at which a thin bitumen film cracks under controlled bending conditions. It is applied in the petroleum and road construction industries to evaluate the low-temperature performance and brittleness of paving-grade bitumen and polymer-modified binders. The test is critical for quality control and material selection in cold-climate pavement applications.
