Abstract: In the natural environment,the external environment factors directly affect the pavement perfor-mance of Asphalt Pavement.In various diseases of asphalt pavement, there is a common disease called low temperature cracking.Under low temperature conditions,if the asphalt pavement is not subject to constraint,it will shrink in volume.If the asphalt pavement is subject to constraint,it will cause temperature stress.When the temperature stress is equal to ｏｒ about the tensile strength of the asphalt material, it will cause cracks.The main influencing factors of low temperature cracking of asphalt pavement are summarized in this paper,and analysis the temperature crack,then it will point out the measures to reduce the temperature cracks.The per-formance of asphalt at low temperature is worth studying and improving, it is a problem that needs to be solved further
