Guide to Cement-treated Base (CTB)


Book Description

Cement-treated base (CTB) is a general term that applies to an mixture of native soils and/or manufactured aggregates with measured amounts of portland cement and water that is compacted and cured to form a strong, durable, frost resistant paving material. Other descriptions such as soil-cement base, cement-treated aggregate base, cement-stabilized base are sometimes used. This document provides a basic guide on the use of cement-treated base (CTB) for pavement applications. This document provides on overview on the design and construction of CTB for both mixed-in-place and central plant mixed operations. A suggested construction specification is also included.
