Abstract

Unpaved gravel shoulders and embankments with little or no vegetation are vulnerable to erosion from wind and rain as well as from wind whip caused by traffic. Because strength and stiffness are critical design criteria for roadway shoulders and embankments, lime, portland cement, and other additives are commonly used to stabilize soils in these areas. While the use of waste byproducts such as CGR can provide an economical and sustainable alternative for stabilizing roadway embankments and shoulder materials, little research and no full-scale field implementation efforts have been undertaken to assess the use of CGR as a soil amendment for mitigating erosivity. The objective of this study is to evaluate the potential use of concrete grinding residue (CGR) as a soil amendment for stabilizing roadway shoulders and embankments.
