通过大量的计算，得出了框架结构及排架结构在高温差、中温差、低温差作用下伸缩缝间距的合理取值。
Through enough computation, reasonable values of the joint distance of frame and bent structures under high, mediate and low temperature action are attained.

改性沥青桥梁伸缩缝在寒区应用时，由于低温作用普遍开裂，而且填缝料和梁端连接处普遍存在界面裂缝。
Most modified asphalt bridge expansion joints fend to have existed cracks because of low temperature, when they applied in cold area.
