Guide to Cement-Treated Base

Cement-Treated Base

Cement-Treated Base (CTB) is a type of Soil-Cement describing an intimate mixture of native soils manufactured aggregates with measured amounts of portland cement and water that hardens after compaction and curing to form a strong, durable, frost-resistant paving material. CTB is versatile as it can be either mixed in place and compacted after blending, or mixed in a central plant where it is hauled to

Cement-Treated

Cement-treated base (CTB) is a strong, frost-resistant base for a concrete or asphalt pavement wearing surface. CTB consists of native soils, gravels, or manufactured aggregates blended with prescribed quantities of cement and water. CTB can be mixed in-place with on-site soils or mixed in a central plant or pugmill depending on
