Geotechnical

Using cementitious binders to stabilize existing soils and pavement material is a time-saving and cost-effective solution for:

  • Geotechnical applications: soil modification (to expedite construction), soil stabilization (for enhancing strength characteristics) or full depth reclamation (to enhance the base portion of pavement), and full depth reclamation (FDR) to recycle existing asphalt and create a more durable, cost effective pavement.
  • Environmental remediation: mixing cementitious products such as cement, slag, cement kiln dust or fly ash into contaminated soil will convert heavy metals into non-hazardous (leachable) forms (stabilization), or encapsulate organic contaminants in situ (solidification).

Why not remove the material and replace it with aggregates?

  • Eliminating “dig and haul” reduces labor and equipment for excavation. It also means less trucking to and from the jobsite, saving fuel and reducing the chances of truck accidents.
  • Reusing the existing material means it is treated and not relegated to outside landfills. Waste material becomes an engineered construction product.
  • It is a proven approach, identified by the U.S. Environmental Protection Agency as a Best Demonstrated Available Technology for more than 50 Resource Conservation and Recovery Act (RCRA) listed wastes.
 
Fly Ash

Added to cement, fly ash can improve workability and consolidation, as well as increase flexural and compressive strengths.
