摘 要
公路和市政道路工程是基础设施建设的重要组成部分.路面平整是评价路面使用性能的一个重要指标,它直接影响着车辆在路面上的行驶质量和道路基本功能的充分发挥.因此路面平整度的改善和提高一直作为沥青路面施工中的一项关键技术而受到道路科技界关注和重视.尽管已经存在着不少有关沥青路面平整度的研究文献,目前公路和市政道路沥青路面机械化程度高,施工工艺和质量要求严格,检验评定标准不断提高,建设单位有的超规范要求,但铺筑路面的平整度有时仍不尽人意,存在影响行车安全、车速及舒适性的隐患.因此认真分析探讨影响道路平整度的因素、提出应予重视、改善和提高平整度的技术措施非常必要.
关键词 :城市道路、公路、沥青路面、平整度
Highway and municipal road projects of infrastructure construction of an important component.Pavement is to evaluate pavement performance is an important indicator,which directly affects the vehicle on the road ride quality and road basic functions into full play.Therefore,pavement improvements and enhancements have been as asphalt pavement construction is a key technology by the road sector concern and attention.Despite the existence of many of the bituminous pavement research literature,the current highway and municipal road asphalt pavement high mechanization,construction techniques and stringent quality requirements,inspection and evaluation standards are being continuously improved,
Construction units and some super-regulatory requirements,but the flatness of paved roads,and sometimes fall short of expectations,there is for traffic safety,speed and comfort of the hidden danger.Therefore,a careful analysis of the factors that affect the flatness of the road is proposed must be given to improve and enhance the flatness of the technical measures is imperative.
