Stabilization is the process of improving undesirable characteristics or conditions of soils and aggregates to the degree where they can be used as a base or pavement structure in the construction of streets, highways, airports, dams, ect. , by the introduction of additives into the soil. With the scarcity and high cost of aggregate, the need for a mobile, in place, mixing machine developed. This led to the design of the RayGo Gator soil stabilizer. This paper will discuss the design features and application of this machine.
