水稳层摊铺新工艺:解决离析、压实是关键

The Key Point of New Water-stabilized Paving Technology is to Solve the Problems of Liquate and Compaction

我国高等级公路建设中，水稳层摊铺碾压是很重要的环节、长久以来，水稳层一直采用双机分层分幅摊铺工艺，近几年，市场出现了水稳层宽幅大厚度摊铺一次成型的新工艺，带动了大厚度大宽度摊铺机和超重吨位压路机的面市，对于这样一项全新的摊铺工艺和新设备，到底取得了什么样的技术进步？在实际中施工应用效果如何？施工中又如何面对国家规范与现实需求的矛盾？记者就此展开了一系列采访。

In recent years, the technology of one- time pavement with thick and wide single machine, changed from the water-stabilized layer pavement with layering dual-machine, has appeared in the road construction market. The pavement thickness of water-stabilized layer with this technology is more than 20cm and the width more than 8cm. With the use of the technology, the water-stabilized layer will be made into an integrated plate structure and the efficiency and quality are also substantially raised. In terms of the construction Parties and the proprietors, the new technology has some advantages when compared with the layering and framing construction,
