随着杭州市城市交通流量逐年增长,公众对道路安全和驾驶舒适感的期望日益提高,杭州市城市道路路面面层结构呈现出以普通沥青混凝土材料为主,而SBS改性沥青混凝土材料、SMA沥青混凝土材料、透水沥青混凝土(PA)材料等新型改良的沥青路面材料则正逐步得到广泛应用。为了更好地满足公众对道路交通的要求,本文从对沥青混凝土路面结构功能特性的分析比较入手,运用全寿命费用一效益的分析比较方法,为科学经济合理地选择路面面层结构提供一定的参考依据。
With the increasing urban traffic flow in Hangzhou and the increasing public expectations of road safety and driving comfort, the pavement structure of urban road pavement in Hangzhou shows an ordinary asphalt concrete material. However, SBS modified asphalt concrete material, SMA Asphalt concrete materials, water-permeable asphalt concrete (PA) materials and other new improved asphalt pavement materials are gradually being widely used. In order to meet the public demand for road traffic better, this paper starts with the analysis and comparison of the functional characteristics of asphalt pavement structure. By using the analysis and comparison method of cost-effectiveness and life-span analysis, this paper provides a scientific method for choosing the road surface structure scientifically and economically Reference.
