GB/T 38948-2020 "Evaluation method for the cracking resistance of asphalt mixture at low temperature"

This standard specifies the test equipment, steps, calculation methods and test reports for evaluating the low temperature crack resistance performance of asphalt mixtures for highway use. It is suitable for various hot-mix, warm-mix and cold-mix asphalt mixtures with a maximum particle size of 26.5 mm. Through standardized testing, the crack resistance performance of asphalt mixtures in low temperature environments can be effectively evaluated, providing a scientific basis for material selection and quality control in highway construction.
