USP低温环保改性沥青在城市道路的应用研究

Application research of USP low temperature modified asphalt in urban road

USP低温环保改性沥青具有低碳节能环保的特性,节约燃料费用50%以上,降低碳排放90%以上,比传统的热拌沥青混合料的温度要低30℃~50℃,在城市道路对环境要求较高的地方施工独具优势,以某市政道路项目为例,分析并探讨了低温环保改性沥青在高温稳定性、低温抗裂性、水稳定性和抗疲劳等方面的路用性能,结果表明USP低温环保改性沥青具有广阔的应用前景。

USP low temperature modified asphalt has the characteristics of low carbon energy conservation and environmental protection.It saves fuel costs by more than 50% and reduces carbon emissions by more than 90%.Compared with the traditional hot mix asphalt mixtures,its temperature is 30 ℃~50℃ lower which obtains an advantage in the construction in the city of high environmental requirements.Taking a municipal road project as an example,this paper analyses and discusses the road performance of low temperature environmental protection modified asphalt in high temperature stability,low temperature crack resistance,water stability and fatigue resistance.The results show that USP low temperature modified asphalt has a broad application prospect.
