Stabilization of Expansive Soil Using Injection of Liquid Ionic Soil Stabilizer: A Case Study between Field and Laboratory Treatment
Expansive soils for residential projects are often treated with liquid ionic soil stabilizer using deep pressurized injection method. Liquid ionic soil stabilizers (LISSs) have a long history of application in practice. However, its treatment effect has not been well documented both in the laboratory and in the field due to the proprietary nature of the liquid chemicals. In this paper, a home construction site in Burleson, TX, was selected for the study of a liquid soil stabilizer. Both Shelby tube and bulk soil samples were collected from the construction site before chemical injection treatment and after the treatment. The Atterberg limits test, linear shrinkage test, 1-D swell, swell pressure, and swell fatigue tests were carried out on the untreated and treated samples in the laboratory before and after treatment. Furthermore, the results from the hand-mixed sample were compared with those of Shelby tube samples to evaluate the feasibility of the lab mixing method. The test results show LISS is effective in the reduction of PI, shrinkage, and swell pressure. Similar swell reductions were observed between Shelby samples and bulk samples treated by the same LISS concentration. However, Shelby tube specimens swell much faster and have higher swell fatigue resistance as compared with the remolded specimens.
