BRT专用车道站台段钢桥面铺装的一种解决方案

A Solution Scheme of Steel Deck Pavement for Platform Section of BRT Special Lane

BRT专用车道的定点停车位作为铺装的薄弱点,若铺装层的高温动稳定性不足将造成该处形成剪切推移、车辙等病害。以贵阳市中环路为背景,对BRT专用车道站台段钢桥面铺装的四个方案进行比选,并选取热拌式沥青混凝土作为实施方案,经验证效果良好,可为国内外的类似工程提供参考。

The fixed parking space of BRT special lane is the weak spot of pavement. The insufficiency of high temperature dynamic stability will cause the diseases of shear displacement and rutting at this place.Taking the Middle Ring Road of Guiyang as the background, this paper compares and selects four schemes of steel deck pavement for the platform section of BRT special lane, and selects the hot-mixed asphalt concrete as the implementation scheme. The effect is good after the certification, and can be referred for the similar projects at home and abroad.
