The Technique of Road Construction for Laying Two-cindess-base by Machine

摊铺机施工二灰砂砾基层技术具有平整度好、路基宽度一次达到设计值、混合料采用集中厂拌含水量容易控制、摊铺厚度便于检查调整等特点,为目前市政道路工程中的一种先进施工技术。以营口市经济技术开发区望海路市政道路工程为例,研究采用德国产ABG423型摊铺机摊铺基层二灰砂砾混合料的工程特点和施工工艺。

The technique of laying twocindessbase by machine is, at present, an advanced one in city road construction due to the facts that the evenness of road surface can be made much better, the width of road base can be reached to the designed value in one turn, the watercontend of the stuff made in the same factory is easy to control, and the laying thickness is convenient to check and adjust. This paper studies the engineering characters and construction technology of this technique with the machine ABG423 made in Germany, taking the city road project of Wanghai road in the economy developing zone, Yingkou City, as example.
