Experimental Study on Pavement Performance for Sandy Soil Stabilized by Soil Stabilizer

Abstract

In order to protect natural environment and save construction cost, both the physical and mechanical properties and the strength change laws of stabilized sandy soil mixture were studied in this paper based on the characteristic of sandy soil stabilized by Lufeng-1 soil stabilizer. The results show that the pavement performance indexes of the sandy soil stabilized by soil stabilizer completely meet the design requirements of every pavement structure layer below base in certain proportion and the optimum proportions for pavement roadbed, sub-base and base materials also are recommended, which provide technological foundation for the utilization of sandy soil.

Use of Alkali-Activated Slag as an Environment-Friendly Agent for High-Performance Stabilized Soil

“…After modification by a stabilization agent, the silt soil exhibits an increased compactness and decreased water content, along with an improved physical property and mechanical performance [ 8 ]. Previous studies demonstrated that the stabilized soil can be used as a preferable construction material due to its good volume stability, mechanical properties, freeze-thaw resistance and low engineering cost [ 9 , 10 , 11 , 12 , 13 ].…”
