目前,国内(底)基层的摊铺大多停留在双机联铺的层面上,致使摊铺效果不理想且隐患较多。本标段采用大厚度底基层一次性摊铺施工方法,此方法在国内使用次数较少,本课题旨在通过本工程施工的实践和研究,在一次摊铺压实施工技术和工艺上开拓创新,为国内底基层施工工艺中实现突破、使其成为底基层施工的一种新工艺、新工法,为推动路面工程施工技术的发展做出贡献。
At present, most of the domestic (bottom) grass-roots paving stops at the level of double-deck joint shops, resulting in unsatisfactory paving effects and more hidden dangers. This section uses a large thickness of the base course of a one-time paving construction method, this method is used less frequently in the country, the purpose of this project through the construction of the practice and research, paving compaction in a construction technology and technology pioneering and innovative , To achieve a breakthrough in the domestic sub-base construction technology, making it a new technology and new work method for the construction of sub-basement, contributing to the development of pavement engineering construction technology.
