Abstract

Cement treatment of aggregate base materials has been utilized in pavement construction since the 1930s (1). The addition of cement increases the strength and stiffness of the treated material and therefore offers greater structural support to the surface layer and greater protection of the underlying subgrade. However, the use of excessive amounts of cement can produce overly stiff base materials that exhibit brittle behavior under heavy traffic loading; the susceptibility of cement-treated base (CTB) materials to cracking increases with increasing stiffness.
