摘要
公路工程是一类地域性很强的工程项目。为寻找在特定自然条件和约束条件下能满足要求且路用性能优势发挥最充分、经济性又最佳的混合料方案,建立一种新的技术经济性能分析模型和评价方法,能较全面、定量地分析PE-Y改性沥青混合料的路用性能优势和经济性,准确评价应用PE-Y改性沥青混合料的技术经济效益,并寻找合适的应用环境。该模型与沥青及沥青混合料气候分区建立联系,能实现在小范围内、因地制宜地优选出与当地气候环境条件最为匹配的沥青混合料,并附以实例。
Highway engineering is a kind of engineering project with strong regional characteristics.In order to find a mixture scheme which can meet the requirements and give full play to the advantages of road performance under specific natural conditions&constraints,a new technical,best economic performance analysis model&evaluation method are established,which can comprehensive quantitatively analyze the road performance advantages&economics of PE-Y modified asphalt mixture,accurately evaluate the technical&economic benefits of applying PE-Y modified asphalt mixture,and find a suitable application environment.This model establishes a relationship with the climatic zone of asphalt&asphalt mixtures,and can realize the selection of asphalt mixtures that best match the local climate&environmental conditions in a small range according to local conditions,with examples.
