In China, class II and below highways account for the majority. According to the constraints of traffic axle load composition and construction funds, inorganic binders such as lime, lime fly ash and so on are generally used to strengthen the soil as the pavement bottom layer and bottom layer. However, in practice, the problems of low early strength, poor water stability, lack of durability and complex construction technology of lime stabilized soil and lime fly ash stabilized soil have seriously affected the highway construction quality and service life. There are many methods of soil reinforcement, generally including physical, chemical and comprehensive reinforcement methods. Although there are many methods, in many methods and processes, the selection of reinforcement data is the key, which is the basis of whether to reach the intention of soil reinforcement, save investment and shorten construction period.

土壤固化剂是一种综合性加固新技能，它是在土壤中加入外加剂使之能与土壤发生一系列的物理以及化学变化，从而改变土壤的物理力学性质，到达工程建造要求。由于土壤固化技能适用范围广、加固效果好、施工简易方便，十分合适现在公路路基及基础加固等实践工程的需要。论文在对土壤固化剂的国内外研讨现状进行分析的基础上，选用室内、外试验对土壤固化剂的固化机理和路用功能进行了研讨；根据合作比优化规划，提出了合作比方案。

Soil solidifying agent is a new comprehensive reinforcement skill. It adds additives to the soil to make it have a series of physical and chemical changes with the soil, so as to change the physical and mechanical properties of the soil and meet the requirements of engineering construction. Due to the wide application range, good reinforcement effect and simple and convenient construction of soil solidification skills, it is very suitable for the needs of practical projects such as highway subgrade and foundation reinforcement. Based on the analysis of the research status of soil curing agent at home and abroad, this paper selects indoor and outdoor tests to study the curing mechanism and road function of soil curing agent; According to the optimal planning of cooperation ratio, a cooperation ratio scheme is proposed.

在合作比情况下，测试了混合料的无侧限饱水抗压强度、水稳性系数、冻安稳系数、抗缩短功能、抗疲劳功能等路用功能；一起和石灰安稳类资料进行了对比、分析；经过实体工程对土壤固化剂在工程中的运用进行了验证，一起提出了施工关键和质量控制的要害问题。研讨结果表明：土壤固化剂安稳类资料能大幅度进步安稳土前期强度，可以有用缩短工期，节省出资；土壤固化剂加固土具有较好的水稳性、抗缩短功能及其他力学功能，可以进步公路运用质量及延长运用寿命。土壤固化剂在冷再生施工中具有广阔的运用远景。

Under the condition of cooperative ratio, the road functions of the mixture such as unconfined saturated compressive strength, water stability coefficient, freeze-thaw stability coefficient, anti shortening function and anti fatigue function are tested; And lime stability data are compared and analyzed; The application of soil solidifying agent in the project is verified through the solid project, and the key problems of construction key and quality control are put forward together. The results show that the data of soil stabilizer can greatly improve the early strength of stable soil, effectively shorten the construction period and save investment; Soil curing agent has good water stability, anti shortening function and other mechanical functions, which can improve highway application quality and prolong service life. Soil solidifying agent has a broad application prospect in cold regeneration construction.

场地整平好后，依照规划要求，用水散撒布车均匀的撒布水泥。水车内装有按一定份额溶解好的固化剂，冷再生机推着水车前行，一根水管连接与水车的水箱及冷再生的水泵，冷再生机均匀前行，水泵的流量由冷再生机的流量计控制，这样冷再生机的拌和室内土壤、水泥、固化剂、水就会均匀的拌和起来。

After the site is leveled, the cement shall be evenly distributed by water spreader according to the planning requirements. The water truck is equipped with curing agent dissolved according to a certain share. The cold regenerator pushes the water truck forward. A water pipe is connected with the water tank of the water truck and the cold regeneration water pump. The cold regenerator moves forward evenly. The flow of the water pump is controlled by the flowmeter of the cold regenerator, so that the soil, cement, curing agent and water in the mixing room of the cold regenerator will be mixed evenly.
