Research progress on the crack resistance of asphalt mixes in cold regions
This paper reviews the progress of the research on the low-temperature performance of asphalt and asphalt mixtures from the perspectives of material research and structural design of pavements.In ad-dition,the research on the low-temperature performance of asphalt and asphalt mixtures at both domestic and international level in recent years is introduced from three perspectives:Evaluation of the low-temper-ature performance of asphalt,evaluation of the low-temperature performance of asphalt mixtures and evalu-ation of the low-temperature performance of mixtures through simulation.It is believed that the low-tem-perature performance of pavements in cold and wide temperature difference areas should be explored on the basis of material research and pavement design,the evaluation indexes of low-temperature performance of durable pavements adapted to cold and wide temperature difference climatic conditions should be estab-lished and in-depth research should be carried out on the trend of cracking-resistant mechanical properties of asphalt mixtures from the field of mechanic simulation and modeling at the same time.
