TST橋梁伸縮縫又叫瀝青填充式橋梁伸縮縫它是無縫伸縮縫粘接料的一種，是七十年代由英國發展起來的一種橋梁伸縮縫技術。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荷作用產生的橋面板位移，而保證表層不會開裂損壞。無縫伸縮粘接料能夠同時兼顧高溫和低溫、滲透和粘性這些對立的性能要求，不僅適用于溫度單一地區，而且適用于溫差較大的地區。
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無縫伸縮縫產品特點：
TST seamless expansion joint product characteristics:
TST無縫伸縮的彈性恢復力非常高：能適應不斷重復的溫度和荷載位移。
The elastic resilience of TST seamless expansion is very high: it can adapt to repeated temperature and load displacement.
低溫柔性和高溫穩定性都非常好：在-40℃時不會變脆，在80℃時不會流動。因此，能適用于中國所有氣候區。
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：施工時可與現有路面牢固粘結，常溫一點兒也不粘，冷卻后又不會被粘帶走。
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.
開放交通迅速： 無縫伸縮縫粘接料安裝后兩個小時即可開放交通，若噴水加速冷卻，一小時后即可開放交通。
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：嚴格按照工藝要求安裝的無縫伸縮縫粘接料，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：無縫伸縮縫粘接料能充分吸收車輛振動沖擊，車輛駛過舒適平穩。
Comfort is very good: seamless expansion joint adhesive can fully absorb the impact of vehicle vibration, vehicle ride comfortably and smoothly.
經濟效益好：成本低廉。
Good economic benefit: low cost.
TST無縫伸縮縫安裝注意事項：
Notes for installation of TST seamless expansion joint:
1.伸縮縫在安裝前一旦碰撞變形，很難修復為合格產品，所以在安裝的全過程中，一定要采取措施保護，嚴禁任何車輛通過。
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.安裝伸縮縫要求嚴格，一定要精心操作。由于現場不易調整，所以成品檢查一定要認真、仔細。不合格不可運至現場。
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，要與設計圖和現場核對位置、尺寸無誤后，再穩放入預留槽。
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，防止澆注保護帶混凝土時灌入，使縫失效。同時，也不可將裝置內灌進混凝土，以免更換V形象膠帶時受阻。
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.伸縮縫保護帶混凝土澆筑后，前七日一定要及時灑水養護，以利強度增長和防止裂縫出現。
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.
