水泥混凝土桥面超薄铺装层材料优选及配合比设计

Material Selection and Design of Mix Proportion of Thin Cement Concrete Bridge Deck Pavement Layer

水泥混凝土桥面铺装厚度减薄,对铺装层材料的性能要求会更高。研究了小粒径沥青混合料、非碾压型沥青混合料、复式微表处混合料和橡胶沥青混合料。试验结果表明,该研究成果可适应不同桥面装结构的要求。

Higher requirements for the performance of pavement material will come with the thinner pavement layer of cement concrete bridge deck. This paper researches small particle size of asphalt mixture, non-compacted asphah mixture, multiple micro-surfacing mixture and rubber asphalt mixture. The experiment result shows that the research results can adapt to the requirements of different bridge deck structure.
