Hello Group, So currently I am looking at utilizing cement stabilized soil at one of my worksites for erosion control and subbase strengthing. Having looked into my state's highway design manual and a the "greenbook" I have not found anything discussing how to determine how much cement is needed to strengthen the soil to the levels I want.
Data are presented from design mix studies and field-testing programs to illustrate the effect of increasing concentrations of the key materials in the mix design and also the impact of other factors such as time on the measured properties. Comparisons are made between soil-cement and SCB materials as used in slurry walls and other types of

After a job-mix has been ap-proved, the source, character, or grading of the soil and the type, brand, or quantity of cement or pozzolanic mate- ... material and mix proportions will produce soil-cement ...
Abstract: Cement-treated base (CTB) is a mixed-in-place or central-plant-produced material consisting of soil/aggregate, cement, and water that creates a strong and durable stabilized roadway base. This guide to CTB discusses its applications, benefits, design, construction, testing, and performance.
