弹塑体改性沥青桥梁伸缩缝的研究及应用

Study and Application of Expansion Joint of Plasto-Elastic Material Modified Asphalt Bridge

弹塑体改性沥青桥梁伸缩缝的应用,使得伸缩缝工作区的材料变形在外力作用下基本保持一致,从而弥补了钢柔间结合部位变形的差异,给车辆顺利通行提供了便利条件,同时,也保证了的人员的舒适。

Applying the expansion joint of plasto - elastic material modified asphalt bridge would make the deformation of materials in working area for expansion joint keep coincident under action of external force and eliminate the difference in the deformation of combining position between rigid structure expansion joint and flexible deck paving layer, which offer a convenient conditions for vehicle passing through smoothly, and ensure the comfort of driver and passengers as well.
