Cement Treated Base (CTB)
We manufacture and sell Cement Treated Base (CTB) which is designed from local DOT rock sources. To achieve our needed gradation, we extract our aggregate from a local 3” base rock. We combine this with measured amounts of Portland cement and water that hardens after compaction and curing to form a durable paving material.
CTB is widely used as a pavement base for highways, roads, streets, parking areas, airports, material handling & storage areas. Other descriptions of CTB are Soil Cement, Cement Treated Aggregate Base or Durarock.
Soil Cement and Cement Treated Base has advantages over other base materials, it continues to gain strength with age, typically cost less than concrete pavement, and can withstand heavy truck and equipment traffic. Hard, rigid Cement Treated Base is practically impervious. It resists rain and spring-weather damage.
CTB Soil Cement
Soil Cement’s 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.
Our limestone is graded down to meet the usages for State, County and City specifications. This material is then engineered and designed to meet the PSI specifications for CTB Soil Cement and Durarock.
Typical cement content ranges from 3% to 6%, resulting in 7 day unconfined compressive strengths from 300 to 800 psi.
Blue Diamond Materials Cement Treated Base is mixed in our twin shaft pug mill plant in Webster, FL. Our materials are shipped to the site, then spread and compacted to form a hardened & durable base.
