Soil stabilization is the alteration ofsoil properties to improve the engineering performance of soils. The propertiesmost often altered are density, water content, plasticity and strength.Modification of soil properties is the temporary enhancement of subgradestability for construction. The course material is based entirely onFHWA-IF-03-019 Technical Report Chapter Number 7 of Fly Ash facts for HighwayEngineers.

At the conclusionof this course, the learner will have a better understanding about theUtilization of fly ash for soil improvement in geotechnical applications aswell as the following:

• Understanding about the vital role of fly ash for soil improvement
• Understanding applicability of fly ash for various geotechnical applications
• Knowledge regarding the modification of soil properties by adding fly ash
• Knowledge of various specification requirements for using fly ash in soil improvement application
