Vertical or near-vertical pavement edges often result in severe erosion at the pavement edge resulting in an unsafe pavement edge drop-off. The present Colorado Department of Highway's typical section has a vertical drop at the shoulder edge as a result of uniform width pavement lifts. The report describes possible problems with this design and submits suggestions on using a tapered asphalt edge to eliminate them. Use of tapered shoulders should be considered on a project-by-project basis depending on the stability of the shoulders. Many areas of eastern Colorado have severe shoulder erosion problems due to the inability of sandy soil to support vegetation. In such areas, tapered shoulders may be cost effective.
