| The issue had selected Ionic soil stabilizer—BTS soil stabilizer to improve the silty clay of Guangxi University. The improved soil was used as highway materials and replace or partly replace cement stabilized gravel pa-vement base, to strengthen the road construction technology and improve road construction period. After the success of the improvement, it is expected to bring us great social environmental and economic benefits.Firstly, this article analyzed the basic indicators of silty clay by geotechnical experiments. Through combing curing mechanism of BTS soil stabilizer, it also makes an in-depth analysis on the action mechanism of BTS soil stabiliz-er im-proveing silty clay.Secondly, this paper also mentions the physical properties and mechanical properties of improved soil. The best mixture ratio of curing agent was confirmed based on unconfined compressive strength and splitting strength and some other physical parameters. Further study focuses on water stability, modulus of resilience and dry-wet cycling test of solidified soil according to the best mixture ratio. A more comprehensive study of curing agent to improve the comprehensive mechanics performance index of the improved soil is to provide date support for using on highway. Finally, through combining the above test data, this paper uses the element analysis software to analyze the improved soil optimal combination and the proposed traditional pavement structure. Two dimensional calculation simulation under the situation of standard vehicle was calculated to analyze the results of two kinds of water stable layer stress, which is usedto verify the curing effects of silty clay as the feasibility of water stable layer. |
