针对寒冷地区中小交通量公路建设中,砾石资源丰富、施工期短、适宜采用冷拌或温拌技术施工的特点,通过对砾石沥青路面的适应性、材料选择、结构形式选型等方面的研究,完善了砾石沥青路面技术;丰富了砾石沥青结合料外掺剂种类配置,阐述了砾石沥青路面用于半刚性基层路面面层和二、三级公路路面下面层的设计要点,提出了适用于寒冷地区的砾石沥青路面典型结构,拓展了砾石沥青路面应用范围。
In view of the characteristics of gravel asphalt pavement adaptability, material selection and structure type selection in the middle and small traffic volume highway construction in cold area, the gravel resource is rich, the construction period is short, and it is suitable to adopt the technology of cold mix or warm mix. , Improved gravel asphalt pavement technology; enriched gravel asphalt binder admixture species configuration, described the gravel asphalt pavement for semi-rigid base pavement and second and third class road pavement design of the main points of the road, put forward suitable for The typical structure of gravel asphalt pavement in cold area expands the application range of gravel asphalt pavement.
