The Elimination or Mitigation of Hazards Associated With Pavement Edge Dropoffs During Roadway ResurfacingAuthor/Presenter: Humphreys, Jack B.; Parham, J. Alan
Shoulders are used on U.S. highways as a safety feature. They are required to meet specifications for width and stability. However, roadways are often resurfaced and the shoulders are not brought up to the new roadway level. This can lead to tires dropping off the pavement edge and possibly to a collision. This study was performed to determine the extent of the pavement edge dropoff problem and recommend changes in contract scope or performance that will eliminate or mitigate such occurrences.
