公路桥桥面铺装结构设计及材料选配

结合桥面铺装工程的实例,对桥面铺装结构设计和材料选配进行了探讨。以交通荷载条件、桥梁结构型式为基础,认为提高沥青技术指标,完善防水黏结层和沥青混合料结构型式并掺加抗车辙剂,可大大提高沥青混合料的热稳定性,提高其自身的强度。这种桥面铺装结构,能更适应使用条件,延长使用寿命。

Design of Highway Bridge Deck Pavement Structure and Selection of Materials Applicable

With examples of deck pavement works, studies are carried out on the deck pavement structure and the selection of material applicable. With the traffic load as the prerequisite and the structural type of bridge as the base, it is held that the heat stability and strength of the asphalt mixture can be improved greatly by raising the technical index of the asphalt, improving the composition of the waterproof bonding course and the asphalt mixture and mixing the anti-rutting agent. This type of deck pavement is more adaptable to the service conditions and its service life is longer.
