东海大桥桥面沥青铺装设计研究

Research on deck asphalt pavement design for Donghai bridge

东海大桥是一座超长跨海大桥,它承担洋山深水港繁重的货物运输,其桥面沥青铺装设计从保证良好的抗车辙性能、耐疲劳性能等出发,采用浇注式沥青混凝土和沥青马蹄脂碎石分别摊铺作为下层和上层,至今桥面表现出良好的使用状态。

Donghai bridge which is a over--long bridge in out--sea bears heavy goods transportation. In order to obtain excellent performances for asphalt deck pavement, such as resistance rutting, durability and so on, a new type of double layer asphalt deck pavement were designed. Gussasphalt concrete and stone mastic asphalt were paved respectively as lower layer and upper layer of deck asphalt pavement. Deck asphalt pavement for Donghai bridge have been in a favorable service condition up to now.
