Benefits of Cement in FDR and Stabilization

WHAT IS CEMENT?

According to cement.org, Cement powder is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. More commonly, it is one of the basic ingredients of concrete when combined with sand, rock, and water. Cement and water combine to make the paste that binds the sand and rock together to produce concrete.

Full Depth Reclamation. Blending cement into the pre-pulverized homogenous mixture of asphalt, aggregate base and subgrade strengthens the entire treated section without removing your existing road or parking lot assets (aggregate base and asphalt).

Base Stabilization. Similar to FDR (also referred to as Cement Treated Base), cement can be added to existing aggregate base after asphalt is milled and removed to dry and strengthen your aggregate base layer prior to new pavement installation.

Subgrade Stabilization. If your silty and sandy sub-grade is too wet to compact and pass a proof roll, you can blend cement to reduce the moisture, re-compact, and pass your proof roll.

Soil Stabilization. On wind farms, it doesn’t pay to build your traditional 12” aggregate road for temporary construction access to the turbine site. By using cement to strengthen the top 8”-14” of soil you eliminate the need for deeper excavation, geogrids, and reduce the quantity of aggregate needed to build your road.

TYPES OF CEMENT

Portland Cement, Soil Cement, and Cement Slag can be used as chemical stabilizers for Soil Stabilization, Sub-grade Stabilization, Base Stabilization, or Full Depth Reclamation. Cement is one of the most versatile and readily available stabilizing materials in the nation, and plays a vital role in supporting our nations infrastructure responsibly.
