Fine Grading for Pavement - constructionmentor.net

Fine Grading for Pavement. Achieving finish grades is typically made possible by finish grade stakes placed by the surveyor. On the stake will be a cut or fill notation and an indicator showing where the final grade should be, allowing the contractor to subtract the depth of the pavement material to acquire top of aggregate base elevation.
