Abstract
The article deals with issues of resistance to cracking at low temperature, low-temperature characteristics of asphalt concrete, tensile strength in bending, and the ratio of tensile strength to bending deformation, which reflects the flexibility of asphalt concrete.When the temperature is relatively low, the asphalt concrete should have a certain deformation capacity, and the temperature shrinkage crack can be reduced under the low temperature condition. The ultimate flexure tensile strain at low temperature is closely related to the performance of asphalt. Increasing the viscosity of asphalt can improve the low-temperature crack resistance of pavement
