The asphalt pavement design with low rolling resistance is a pavement design that reduces the rolling resistance of the road through the exploration of asphalt modification.By observing the microscopic characteristics of low-rolling asphalt,the modification mechanism of low-rolling asphalt was explored.The road performance test is designed to ensure that the road performance index of the low rolling resistance asphalt mixture meets the requirements of the specification;Based on the use scenarios and characteristics of low-rolling resistance asphalt,the characteristics of low-rolling resistance asphalt pavement under dynamic loading environment are evaluated through dynamic modulus test and finite element simulation model,which provides a new reference idea for low-rolling resistance asphalt in road design.
