提高综合稳定粉性土底基层强度和稳定性措施

Measures of improving the bottom base strength and stability of comprehensive stable silty soil

通过对S233省道三垛—江都港区段SJL2标粉性土的CBR承载比和无侧限抗压强度试验结果分析,确定了底基层综合稳定土配合比方案,介绍了底基层综合稳定粉性土的施工质量控制要点,以保证路面底基层的强度和稳定性。

Through analyzing the experimental results of CBR bearing ratio and unconfined compression strength of silty soil at Sanduo-Jiangdu harbor section SJL2 on provincial highway S233,the paper determines the comprehensive stable soil mixing proportion scheme of bottom base,and introduces the construction quality controlling points of comprehensive silty soil at bottom base,with a view to guarantee the strength and stability of the bottom base of the pavement.
