摘要
针对高寒地区的特殊气候条件,结合郎川公路改建工程水泥稳定碎石基层和底基层施工的实际情况,从半刚性结构层材料的选择、集料质量控制、混合料配合比设计、施工工艺与混合料的均匀性、气候环境及养生措施、交通管制等方面,探讨了减少半刚性结构层温缩和干缩裂缝的施工关键控制技术。
According to the extremely climate condition of cold region of plateau, and combined with cement stabilized aggregate base and subbase construction practice in Lang-Chuan Highway, some construction key techniques for reducing temperature shrinkage and dry shrinkage cracking of semi-rigid structural layer are studied from selection of local materials, quality control of aggregate, design of mixture grade, procedure of construction, homogeneity of mixture, climate environmental condition, measures of maintenance and traffic control during semi-rigid structural layer construction.
