Study On Adaptability Of Asphalt Pavement Maintenance Technology In Kuitun Area Of Xinjiang

The location of Kuitun City in Xinjiang is the transportation hub of North Xinjiang.The G30 line connecting Lian Huo Expressway and the G217 line connecting North and South Xinjiang intersect here.The G3014 kui-a highway and the G3015 kui-ta highway also depart from here.(The total length of roads in the maintenance road area of the area is 1014.094 Km,includ ing high-speed 386.339Km;first-grade road 129.714Km;second-and third-level national and provincial roads 498.041Km).In order to ensure the efficient use of maintenance funds,the technical conditions of the highway,the causes of diseases,the natural environment Under the comprehensive influence of factors such as traffic and traffic volume,the correct choice of suitable maintenance technology has become the primary problem of maintenance decision.This paper is aimed at the situation where various maintenance technologies have been applied in the Kuitun area in the past,and the adaptability of various asphalt pavement maintenance technologies in the Kuitun area Conduct research to guide the selection of road maintenance technology in Kuitun area in the future,and provide technical reference for realizing the correct decision of the maintenance plan.From 2015 to 2019,Kuitun area selected a variety of asphalt pavement maintenance technologies such as in-situ cold regeneration,in-situ hot regeneration,fiber crushed stone seal,cap seal,micro-surface,anti-slip surface,cover,and reinforcement.It is applied to 12 maintenance projects.In the selection of asphalt road maintenance technology selection,combined with the actual natural environment of the road section,traffic volume and other related factors,different construction techniques are selected for the road section with the same conditions and conditions for horizontal comparison of maintenance technology.The same kind of construction technology is selected in different sections for longitudinal comparison of maintenance technology,After continuous follow-up observation in the later period,a number of maintenance technologies have been formed in the post-evaluation of the adaptive use of Kuitun area.This article selects 4 maintenance projects with typical application of maintenance technology The decision basis of the maintenance plan,the implementation effect and evaluation of the maintenance technology proposed the adaptability of different asphalt pavement maintenance technologies in the Kuitun area.Through the horizontal and vertical technical adaptability research of different asphalt pavement maintenance technologies,it has important technical reference value to improve the maintenance effect of highways in Kuitun area,extend the service life of highways and further reduce the maintenance cost during the life cycle of highways.
