Sawdust as Lightweight Fill Material
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 using 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%. The asphalt sealed slope should inhibit deterioration and give the sawdust a life 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.
