Cement-Treated Base by RAPID

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

Typical cement contents range from 3 to 10 percent, resulting in 7-day unconfined compressive strengths from 300 to 800 psi.

Cement Treated Base allows contractors to create a strong base for projects with specified minimum durability and strength requirements.

Pavements with Cement Treated Base will be much stronger and more rigid than an unstabilized, granular base. Cement Treated Base thicknesses are less than those required for granular bases carrying the same traffic. It can distribute loads over a wider area, reducing the stresses on the subgrade and acting as the load-carrying element of a flexible pavement or a subbase for concrete.

Its slab-like characteristics and beam strength are unmatched by granular bases that can fail when aggregate interlock is lost. This happens when wet subgrade soil is forced up into the base by traffic loads. Hard, rigid Cement Treated Base is practically impervious. It resists cyclic freezing, rain, and spring-weather damage. Cement Treated Base continues to gain strength with age even under traffic. This reserve strength accounts in part for Cement Treated Base's excellent performance.

The rigidity of Cement Treated Base reduces deflection, rutting in the base and other asphalt strains.The versatility of cement is critical to the success in this pavement solution because site conditions and soil types (from gravel to clays) can easily change during or between projects and cement acts as a "universal stabilizer."
