Soil-Cement FAQs

For base material, is there a cost advantage in using a cement-treated base over an unbound graded aggregate base? Obviously, the difference in cost between a cement-treated base (CTB) and an unbound graded aggregate base (GAB) will vary depending upon location, availability and cost of materials, and costs associated with placing the materials.
