采用5种双层SMA结构形式进行复合梁的动稳定度试验研究,提出5种桥面铺装结构组合都表现出较好的抗车辙性能,其中桥面铺装组合1和组合2(SMA9.5与SMA13相组合)的抗车辙性能更为优越。推荐铺装结构的高温稳定性评价指标和铺装层的结构选用型式。
Five kinds of double-layer SMA structures were used to study the dynamic stability of the composite beams. It is concluded that the five kinds of bridge deck structures exhibit better anti-rutting performance. Among them, the bridge deck pavement combination 1 and combination 2 (SMA9). 5 combined with SMA13) is superior in rutting resistance. Recommended pavement structure of high temperature stability evaluation index and pavement layer structure selection type.
