摘要：2014年7月,韩国政府发布《应对气候变化的零能耗建筑行动计划》,完成了世界第一个国家级零能耗建筑研究推广的顶层设计,分析了零能耗建筑推广的障碍,提出零能耗建筑发展目标和具体实施方案,明晰了零能耗建筑财税政策及技术补贴。同时,韩国设立国家重点研究计划,建立国家级科研团队进行零能耗建筑技术的研发,完成示范工程,建立零能耗建筑认证标准。本文针对韩国零能耗建筑发展的现状,对韩国零能耗建筑的定义、发展目标及规划、财税政策、重点研发计划、典型示范项目及认证标准进行了研究。

摘要：Warm-mix asphalt(WMA) technology was applied for asphalt mixture,plant-produced porous WMA using LEADCAP additive(porous WMA-LEADCAP) test section was built and compacted at 30℃ lower than porous hot-mix asphalt(porous HMA) test *** mix designs were conducted for porous WMA-LEADCAP mixture and porous HMA mixture in terms of Marshall stability,Cantabro loss and dynamic *** workability,compactablity and surface quality of porous WMA-LEADCAP pavement were investigated,and the engineering properties of plant-produced porous WMA-LEADCAP mixture and plant-produced porous HMA mixture were evaluated based on indirect tensile strength test and dynamic immersion *** result shows that LEADCAP additive does not affect polymermodified asphalt in terms of penetration,softening point,viscosity,ductility,toughness and *** WMA-LEADCAP pavement has similar field density,permeability and smoothness compared with standard porous HMA ***-produced porous WMA-LEADCAP mixture is equivalent to plantproduced porous HMA mixture in indirect tensile strength,toughness and stripping resistance.4tabs,4figs,9refs.
