控制和防止反射裂缝是旧水泥路面改造中的一大难题。传统的挖除改造技术存在着许多的弊病,对旧水泥混凝土板碎石化处理技术是目前世界上一种较先进的方法,碎石化技术不但消除了旧板块弃放的白色污染,而且比较彻底地消除旧路面对沥青混凝土面层的反射裂缝,提高了沥青混凝土路面的使用寿命。文章就平青乐线滦县段碎石化施工的实际情况,简要介绍水泥混凝土路面大修中的碎石化技术的原理、机械设备、适用条件及施工工艺。
Controlling and preventing reflection cracks is a major challenge in the reconstruction of old concrete pavement. The traditional excavation and transformation techniques have many drawbacks. The technology of crushing and processing the old cement concrete slab is a more advanced method in the world. The technology of crushing and petrification not only eliminates the white pollution abandoned by the old plates, but also compares Completely eliminate the old pavement on the asphalt concrete reflection cracks, improve the service life of asphalt concrete pavement. This article briefly introduces the principle, mechanical equipment, applicable conditions and construction technology of the crushing technology in the overhaul of cement concrete pavement.
