摘要
水泥稳定风积沙技术的推出,使修路成本节约了 30%以上,施工现场也智能环保,省时省力.将风积沙铸路技术应用对荒漠化综合治理当中,能够为国内外沙漠地区治理提供技术支撑,为沙产业的发展作出应有的贡献.石灰土干缩和温缩比较明显.水泥土干缩系数、干缩应变以及温缩系数的比较:粒料的系数小于土.二灰土:抗冻性比石灰土好.(因为有孔,羽绒服抗冻).收缩性小于水泥土和石灰土.(因为有孔,结构具有一定的伸缩性).本研究首先从干缩特性研究、温缩特性研究两个方面分析了半刚性基层收缩性能与规律研究现状,然后进行了原材料分析.
Abstract
The introduction of cement stabilized aeolian sand accumulation technology has saved more than 30%of road construction costs,and the construction site is also intelligent and environmentally friendly,saving time and effort.The application of aeolian sand casting technology to the comprehensive control of desertification can provide technical support for the treatment of desert areas at home and abroad,and make due contributions to the development of sand industry.Dry shrinkage and temperature shrinkage of lime soil are more obvious.Comparison of dry shrinkage coefficient,dry shrinkage strain and temperature shrinkage coefficient of cement soil:the coefficient of pellets is smaller than that of soil.Second,lime soil:frost resistance is better than lime soil.(Because there are holes,down jackets are frost-resistant).The shrinkage is less than that of cement and lime soil.(Because there are holes,the structure has a certain degree of elasticity).In this study,the research status of shrinkage performance and law of semi-rigid base layer was analyzed from two aspects:dry shrinkage characteristics and temperature shrinkage characteristics,and then raw material analysis was carried out.
