TST橋梁伸縮縫又叫瀝青填充式橋梁伸縮縫它是無(wú)縫伸縮縫粘接料的一種，是七十年代由英國(guó)發(fā)展起來(lái)的一種橋梁伸縮縫技術(shù)。此工藝的基本作法是將接縫上面一窄條范圍的橋面鋪裝層替換為一種高彈性的特殊瀝青混合料。高彈性特種瀝青與石料的混合物可以吸收由于溫度和交通負(fù)荷作用產(chǎn)生的橋面板位移，而保證表層不會(huì)開(kāi)裂損壞。無(wú)縫伸縮粘接料能夠同時(shí)兼顧高溫和低溫、滲透和粘性這些對(duì)立的性能要求，不僅適用于溫度單一地區(qū)，而且適用于溫差較大的地區(qū)。
TST bridge expansion joint, also known as asphalt filLED bridge expansion joint, is a kind of seamless expansion joint bonding material and a bridge expansion joint technology developed from Britain in the 1970s. The basic method of this technology is to replace a narrow bridge deck pavement above the joint with a special asphalt mixture with high elasticity. The mixture of high elastic asphalt and stone can absorb the displacement of bridge deck caused by temperature and traffic load, and ensure that the surface will not crack and damage. Seamless expansion bonding material can take into account the opposing performance requirements of high and low temperature, permeability and viscosity at the same time. It is not only suitable for single temperature area, but also suitable for areas with large temperature difference.
TST無(wú)縫伸縮縫產(chǎn)品特點(diǎn)：
TST seamless expansion joint product characteristics:
TST無(wú)縫伸縮的彈性恢復(fù)力非常高：能適應(yīng)不斷重復(fù)的溫度和荷載位移。
The elastic resilience of TST seamless expansion is very high: it can adapt to repeated temperature and load displacement.
低溫柔性和高溫穩(wěn)定性都非常好：在-40℃時(shí)不會(huì)變脆，在80℃時(shí)不會(huì)流動(dòng)。因此，能適用于中國(guó)所有氣候區(qū)。
Both low temperature flexibility and high temperature stability are very good: it will not become brittle at - 40 ~C and will not flow at 80 ~C. Therefore, it can be applied to all climatic regions in China.
高溫粘附性好：施工時(shí)可與現(xiàn)有路面牢固粘結(jié)，常溫一點(diǎn)兒也不粘，冷卻后又不會(huì)被粘帶走。
Good adhesion at high temperature: construction can be firmly bonded with the existing road surface, normal temperature is not at all sticky, after cooling will not be sticky away.
施工方便、靈活：熟練的施工隊(duì)伍（8-10人）每天可30延米GTF、TST伸縮縫，而且可在不阻斷交通的情況下半幅施工。
Convenient and flexible construction: skilLED construction team (8-10 people) can reach 30 meters GTF, TST expansion joints per day, and can be constructed in half without blocking traffic.
開(kāi)放交通迅速： 無(wú)縫伸縮縫粘接料安裝后兩個(gè)小時(shí)即可開(kāi)放交通，若噴水加速冷卻，一小時(shí)后即可開(kāi)放交通。
Open traffic is fast: two hours after installation of seamless expansion joint adhesives, open traffic, if spraying water to accelerate cooling, open traffic in one hour.
使用壽命長(zhǎng)：嚴(yán)格按照工藝要求安裝的無(wú)縫伸縮縫粘接料，其壽命是一般改性瀝青路面的兩倍左右。
Long service life: Seamless expansion joint adhesives instalLED in strict accordance with process requirements, its service life is about twice that of general modified asphalt pavement.
舒適性非常好：無(wú)縫伸縮縫粘接料能充分吸收車(chē)輛振動(dòng)沖擊，車(chē)輛駛過(guò)舒適平穩(wěn)。
Comfort is very good: seamless expansion joint adhesive can fully absorb the impact of vehicle vibration, vehicle ride comfortably and smoothly.
經(jīng)濟(jì)效益好：成本低廉。
Good economic benefit: low cost.
TST無(wú)縫伸縮縫安裝注意事項(xiàng)：
Notes for installation of TST seamless expansion joint:
1.伸縮縫在安裝前一旦碰撞變形，很難修復(fù)為合格產(chǎn)品，所以在安裝的全過(guò)程中，一定要采取措施保護(hù)，嚴(yán)禁任何車(chē)輛通過(guò)。
1. once the expansion joint collides and deforms before installation, it is difficult to repair it as a qualified product. Therefore, in the whole process of installation, measures must be taken to protect it, and no vehicle is allowed to pass through.
2.安裝伸縮縫要求嚴(yán)格，一定要精心操作。由于現(xiàn)場(chǎng)不易調(diào)整，所以成品檢查一定要認(rèn)真、仔細(xì)。不合格不可運(yùn)至現(xiàn)場(chǎng)。
2. Installation of expansion joints is strictly required and must be carefully operated. Because the site is not easy to adjust, so the finished product inspection must be serious and careful. Unqualified can not be shipped to the scene.
3.伸縮縫安裝前，要與設(shè)計(jì)圖和現(xiàn)場(chǎng)核對(duì)位置、尺寸無(wú)誤后，再穩(wěn)放入預(yù)留槽。
3. Before installation of expansion joints, check the position and size with design drawings and site before placing them in the reserved slot steadily.
4.橋上各接縫處縫隙一定要用聚苯乙烯泡沫板塞嚴(yán)，防止?jié)沧⒈Ｗo(hù)帶混凝土?xí)r灌入，使縫失效。同時(shí)，也不可將裝置內(nèi)灌進(jìn)混凝土，以免更換V形象膠帶時(shí)受阻。
The joints on the 4. bridges must be tightly seaLED with polystyrene foam boards to prevent pouring into the concrete when the concrete is protected. At the same time, concrete can not be poured into the device, so as not to be blocked when replacing V image tape.
5.伸縮縫保護(hù)帶混凝土澆筑后，前七日一定要及時(shí)灑水養(yǎng)護(hù)，以利強(qiáng)度增長(zhǎng)和防止裂縫出現(xiàn)。
5. After concrete pouring of expansion joint protective belt, water must be sprinkLED and maintained in time for the first seven days in order to increase strength and prevent cracks from appearing.
