无缝伸缩缝粘接料是一种沥青填充式桥梁伸缩缝,是七十年代由英国发展起来的一种桥梁伸缩缝。它的基本作法是将接缝上面一窄条范围的桥面铺装层替换为一种高弹性的特殊沥青混合料。这条高弹性特种沥青与石料的混合物可以吸收由于温度和交通负荷作用产生的桥面板位移,而保证表层不会开裂损坏。 无缝伸缩粘接料能够同时兼顾高温和低温、渗透和粘性这些。
TST桥梁伸缩缝也叫无缝伸缩缝粘接料,是一种沥青填充式桥梁伸缩缝,是七十年代由英国发展起来的一种桥梁伸缩缝。TST碎石直接平铺在桥梁接缝处,与前后的桥面或路面铺装形成连续体,桥面平整无缝,行车平稳无嗓音、振动小,便于维护、清扫。构造简单,施工方便,铺装冷却后即可开放文通,这条高弹性特种改性沥青与石料的混合物密封防水性好,能够同时兼顾高温和低温、渗透和粘性等严苛的使用性能要求,且耐酸碱腐蚀,可以吸收由于温度和交通负荷作用产生的桥面板位移,而保证表层不会开裂损坏,不仅适用于温度单一地区,而且适用于温差较大的地区。 关键词:桥梁维护;伸缩缝;施工方法 Abstract: the TST bridge is adjustable seam also called seamless is adjustable seam adhesive materials, is a kind of asphalt fill type jointless bridge, is in the seventy s by the British developed a kind of bridge is adjustable seam. TST rubble in joint direct tile bridge, and the bridge deck pavement shop before and after or form a continuous body, bridge deck level off seamless, driving is stable and no voice, small vibration, easy to maintain, clean up. Simple structure, construction is convenient fast, the shop after cooling can open the text link, a high elastic special modified asphalt mixture with stone seal water proofing property is good, can also give consideration to the high temperature and low temperature, permeability and viscous, the use of harsh performance requirements, and naisuanjian corrosion, can absorb as temperature and traffic load function produce bridge panel displacement, and ensure that the surface does not crack damage, not only applicable to temperature single region, but also suitable for large temperature difference in the region.
