Research on Application of Intelligent Compaction Technology for Solidified Slag Soil Subgrade
Solidification of engineering slag soil is an effective approach for the on-site utilization of poor soil resources.In order to ensure the quality control effect of compaction for solidified slag soil,aiming at the poor timeliness of traditional compaction testing methods and the high demand for real-time performance of solidified slag soil subgrade,and relying on a trunk road,an application practice of intelligent compaction for solidified slag soil subgrades is carried out.The correlativity between the subgrade dynamic deformation modulus Evd and the intelligent compaction indicators is established.The results indicate that intelligent compaction indicators of CMV,CCV,Evib and correlation coefficients are higher than 0.7,which are applicable for compaction control of solidified slag soil subgrades.The correlation coefficient between Evib and dynamic deformation modulus Evd of subgrade can reach 0.844,which is a preferred intelligent compaction indicator.The compaction degree and uniformity in the test section are all good.
