Steel bridge deck asphalt pavement structure and construction method thereof
The invention provides a steel bridge deck asphalt pavement structure and a construction method thereof, and belongs to the technical field of road engineering, the pavement structure sequentially comprises a self-flowing type bonding heat insulation layer, an assembly type bearing layer and a multifunctional wearing layer from the steel bridge deck to the top; an interface binder is brushed between the bottom face of the self-flowing type bonding heat insulation layer and the steel bridge deck, and an aerogel nanometer heat insulation layer is laid on the top face of the self-flowing type bonding heat insulation layer, or a heat insulation ceramic broken particle layer is spread and laid on the top face of the self-flowing type bonding heat insulation layer; and an assembly type bearing layer and a multifunctional wearing layer are laid on the aerogel nanometer heat insulation layer or the heat insulation ceramic broken particle layer. And the assembly type bearing layer is paved by adopting assembly type construction after prefabrication. Interlayer bonding of the asphalt pavement layer and the steel bridge deck is guaranteed, the problem of cooperative deformation of the asphalt pavement layer and the steel bridge deck is solved, the dead weight of the asphalt pavement layer is reduced, meanwhile, the pavement structure has multiple functions of track resistance, pushing resistance, freezing resistance, skid resistance, noise reduction and the like, durability and driving safety are greatly improved, and the steel bridge deck is effectively protected.
本发明提供一种钢桥面沥青铺装结构及其施工工法，属于道路工程技术领域，该铺装结构是从钢桥面往上依次为自流式粘结隔热层、装配式承重层和多功能磨耗层；自流式粘结隔热层底面和钢桥面之间涂刷界面粘结剂，在自流式粘结隔热层顶面铺设一层气凝胶纳米隔热层，或撒布铺设隔热陶瓷破碎颗粒层；气凝胶纳米隔热层或隔热陶瓷破碎颗粒层之上铺设装配式承重层和多功能磨耗层。装配式承重层的铺装采用预制后装配式施工。本发明保证了沥青铺装层与钢桥面的层间粘结，解决了沥青铺装层与钢桥面协同变形的问题，降低了沥青铺装层自重，同时该铺筑结构具有抗车辙、抗推移、抗凝冰、抗滑降噪等多种功能，大幅提升耐久性和行车安全性，有效保护钢桥面板。
