摘要
材料、配合比、生产拌和、施工作业是SBS改性沥青路面质量控制的关键环节;建议在粗集料试验合格和经济条件允许的前提下,尽量选用压碎值小的粗集料做改性沥青混凝土的矿料;指出了配合比设计的关键点;总结了施工控制的关键点:保证温度、连续摊铺、及时碾压、随时检查。
The paper Puts forward the materials, proportioning, mixing production and constructions operations are key links to control of quality of SBS modified asphalt pavement. It makes the suggestions that as much as to select coarse aggregate with minor fracture as minerals for modified asphalt concrete, indicates critical points for proportioning design, sums up major points for construction controlhng. It also indicates ensuring the temp, continuous spread, roiling in time as well as inspection at any moment.
