Study on Optimization Strategy of Anti-skid Performance of Municipal Asphalt Pavement
In order to effectively improve the anti-skid performance of municipal asphalt pavement,ensure the road operation capacity and use safety.In this paper,the optimization strategy of anti-skid performance of municipal asphalt pavement is comprehensively explored,and the influence of raw materials,grading type and proportion of differentiated minerals on anti-skid performance of asphalt mixture is systematically analyzed.The results show:Compared with AC-13 graded mixture,the BPN and DF60 indexes of OGFC-13 increased by 8.6%and 18.5%,respectively.The dense skeleton mineral can significantly enhance the anti-skid ability of asphalt mixture,and has excellent anti-fatigue per-formance.This type of gradation is the best gradation to enhance the anti-skid ability of asphalt pavement.Reasonable increase of mineral frac-tion can effectively improve the anti-skid ability of asphalt pavement,and the optimal proportion of mineral fraction is 30%.
