Repair or replace any metal castings and other surface improvements damaged by planing as confirmed by the Engineer. Plane a tapered wedge cut longitudinally along curb lines sufficient to provide a minimum of 4 inches of curb reveal after placement and compaction of the final wearing course. The dimensions of the wedge must be as shown on the planing plan or as specified by the Engineer. Plane a tapered wedge cut at transitions to adjoining pavement surfaces 111 (meet lines) where butt joints are shown on the Plans. Cut butt joints in a straight line with vertical faces two inches or more in height, producing a smooth transition to the existing adjoining pavement. After planing is complete, sweep and clean planed surface, and if Contract requires, patch and pre-level. The Engineer may direct additional depth planing.
