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，它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。 特点弹性恢复力非常高：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
Expansion joint, also known as seamless expansion jointadhesive, is an asphalt filled bridge expansion joint, whichreplaces a narrow range of bridge deck pavement above the jointwith a special asphalt mixture with high elasticity. The mixture ofasphalt and aggregate with high elasticity can absorb thedisplacement of bridge deck caused by temperature and traffic load,and ensure that the surface will not crack and damage. Seamlessexpansion bonding material can take into account the opposingperformance re of high and low temperature, permeabilityand viscosity at the same time. It is not only suitable for singletemperature area, but also suitable for areas with largetemperature difference. The elastic resilience is very high: it canadapt to repeated temperature and load displacement. Both lowtemperature flexibility and high temperature stability are verygood: 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.Good adhesion at high temperature: it can be firmly bonded withexisting pavement during construction, and not at room temperatureat all.
