GB/T 38948-2020
ActiveEvaluation method for the cracking resistance of asphalt mixture at low temperature
沥青混合料低温抗裂性能评价方法
Application Summary AI generated
This standard specifies a test method for evaluating the cracking resistance of asphalt mixtures under low-temperature conditions, primarily using the semi-circular bending (SCB) test to determine fracture energy and flexibility index. It is applied in civil engineering, specifically for quality control and performance assessment of asphalt pavements in cold regions or during winter construction. The standard is used by road construction agencies, material testing laboratories, and research institutions to ensure pavement durability against thermal cracking.
