摘要:   In this paper,by changing the asphalt mortar of asphalt mixture,we adopt the raw materials of construction site to explore the impact of filler-bitumen ratio to the anti-fatigue performance of asphalt mixture.Using two methods of washing and sieving,which can control the passing rate of 0.075mm sieve pore and trimming the aggregate gradation,to change the composition of asphalt mastic? Then,study the impact of asphalt mastic on the anti-fatigue performance of AC-25 asphalt mixture,by changing the composition of asphalt mortar.Studies have shown that the fatigue life and stress ratio of asphalt mixture by using the same asphalt mastic have certain logarithmic relationship;In the case of gradation basically unchanged or subtle changes occur,the numerical of fatigue life has a quadratic relationship with the filler-bitumen ratio of asphalt mixture,and the most value exists;For the AC-25 asphalt mixture,the anti-fatigue performance of asphalt mixture achieves the optimal when the filler-bitumen ratio is between 1.5 and 1.6.
