Abstract Unstable embankments and potential slide areas have always been an expensive maintenance problem. The Washington State Highway Department recently developed a unique solution to this problem by utilizing a lightweight waste produce-Sawdust. By removing existing high density fill material and replacing it with Sawdust, they successfully repaired an unstable roadway section, reducing the driving weight of this potential slide by 71 percent. The asphalt sealed slope should inhibit deterioration and give the sawdust a lift expectancy of at least 15 years as a stable fill. This application of a waste product appears particularly suited to secondary and country roads with unstable soil conditions where economics often prohibit major slide repair solutions.
