90-A型冷施工式桥梁伸缩缝的研究

Study on 90-A Type Cold-laid and Quick-Consolideted Bridge Expansion and Contraction Joint

本文概述了我国目前公路桥梁伸缩缝的现状,提出一种完全新型的桥梁伸缩缝——冷铺快速固化型伸缩缝,并对其机理、组成材料、结构组合、施工工艺及特点作了详细论述。

The state of art of the expansion and contraction joint of China's highway bridge is briefly reviewed in the paper. A newly deveioped type of expansion and contraction joint i.e. a cold-laid and quick-consolidated joint is then presented. The mechanism and composition materials, structure, construction procedure and characteristic of this joint are also discussed.
