TST bridge expansion joint

TST桥梁伸缩缝又叫沥青填充式桥梁伸缩缝它是无缝伸缩缝粘接料的一种，此工艺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。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、渗透和粘性这些对立的性能要求，不仅适用于温度单一地区，而且适用于温差较大的地区。

TST bridge expansion joint is also called asphalt filled bridge expansion joint. It is a kind of seamless expansion joint adhesive material. The basic method of this technology is to replace a narrow strip of bridge deck pavement on the upper part of the joint to a high elastic special asphalt mixture. The mixture of high elastic special asphalt and stone can absorb the displacement of bridge deck caused by temperature and traffic load， and ensure that the surface will not crack. Seamless stretch adhesive material can take into account both the high temperature and low temperature， osmosis and sticky performance requirements， not only for single temperature area， but also for large areas with large temperature difference.

TST无缝伸缩缝产品特点

Product features of TST seamless expansion joint

TST无缝伸缩的弹性恢复力非常高：能适应不断重复的温度和荷载位移。

低温柔性和高温稳定性都非常好：在-40时不会变脆，在80时不会流动。因此，能适用于中国所有气候区。

高温粘附性好：施工时可与现有路面牢固粘结，常温一点儿也不粘，冷却后又不会被粘带走。

施工方便、灵活：熟练的施工队伍（8-10人）每天可30延米GTF、TST伸缩缝，而且可在不阻断交通的情况下半幅施工。

开放交通迅速： 无缝伸缩缝粘接料安装后两个小时即可开放交通，若喷水加速冷却，一小时后即可开放交通。

使用寿命长：严格按照工艺要求安装的无缝伸缩缝粘接料，其寿命是一般改性沥青路面的两倍左右。

舒适性非常好：无缝伸缩缝粘接料能充分吸收车辆振动冲击，车辆驶过舒适平稳。

经济效益好：成本低廉。

TST seamless resilient resilience is very high able to adapt to constant temperature and load displacement. Low temperature flexibility and high temperature stability are very good it will not become brittle at -40 C， and will not flow at 80. Therefore， it can be applied to all climate zones in China. High temperature adhesion good construction can be firmly bonded with the existing pavement， the room temperature is not sticky at all， and will not be taken away after cooling. Convenient and flexible construction， skilled construction team （8-10）， 30 meter GTF TST expansion joint every day， and can not block the traffic under the condition of half construction. The open traffic is rapid the seamless expansion joint will open two hours after the installation of the joint. If the water is accelerated and cooling， the traffic can be opened in one hour. Long service life the seamless joint adhesive bonded by the seamless expansion joint according to the technical requirements is about two times as long as the general modified asphalt pavement. The comfortableness is very good the seamless joint joint can fully absorb the vibration and shock of the vehicle， and the vehicle is comfortable and smooth. The economic benefit is good the cost is low.

TST无缝伸缩缝安装注意事项

TST seamless expansion joint installation attention

1.伸缩缝在安装前一旦碰撞变形，很难修复为合格产品，所以在安装的全过程中，一定要采取措施保护，严禁任何车辆通过。

1.， once the expansion joint is collided and deformed before installation， it is difficult to repair the qualified product. Therefore， in the whole process of installation， we must take measures to protect and strictly prohibit any vehicle passing.

2.安装伸缩缝要求严格，一定要精心操作。由于现场不易调整，所以成品检查一定要认真、仔细。不合格不可运至现场。

2. installation expansion joint requires strict， and must be carefully operated. Because the site is not easy to adjust， so the finished product inspection must be careful and careful. Unqualified can not be shipped to the scene.

3.伸缩缝安装前，要与设计图和现场核对位置、尺寸无误后，再稳放入预留槽。

3. before the installation of the expansion joint， to check the location and size of the design and site， and then put it in the reserved slot.

4.桥上各接缝处缝隙一定要用聚苯乙烯泡沫板塞严，防止浇注保护带混凝土时灌入，使缝失效。同时，也不可将装置内灌进混凝土，以免更换V形象胶带时受阻。

The gap between the joints on the 4. bridge must be slug with polystyrene foam plate to prevent pouring into the protective belt concrete and failure of the seam. At the same time， the device can not be poured into the concrete in order to avoid the replacement of the V image tape.

5.伸缩缝保护带混凝土浇筑后，前七日一定要及时洒水养护，以利强度增长和防止裂缝出现

After 5. expansion joint protection belt concrete pouring， the first seven days must be timely sprinkler maintenance， in order to increase the strength and prevent cracks
