水泥混凝土桥面超薄铺装层材料优选及配合比设计

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.

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

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.
