2026 Pavement Maintenance Overlay Special Provisions <br />PW# 3860 SP - 70 March 5, 2026 <br />1 Where planing an existing pavement is specified in the Contract, the Contractor must <br />2 remove existing surfacing material and to reshape the surface to remove irregularities. <br />3 The finished product must be a prepared surface acceptable for receiving an HMA <br />4 overlay. <br />5 <br />6 Use the cold milling method for planing unless otherwise specified in the Contract. Do not <br />7 use the planer on the final wearing course of new HMA. <br />8 <br />9 Conduct planing operations in a manner that does not tear, break, burn, or otherwise <br />10 damage the surface which is to remain. The finished planed surface must be slightly <br />11 grooved or roughened and must be free from gouges, deep grooves, ridges, or other <br />12 imperfections. The Contractor must repair any damage to the surface by the Contractors <br />13 planing equipment, using an Engineer approved method. <br />14 <br />15 Repair or replace any metal castings and other surface improvements damaged by <br />16 planing, as determined by the Engineer. <br />17 <br />18 A tapered wedge cut must be planed longitudinally along curb lines sufficient to provide a <br />19 minimum of 4 inches of curb reveal after placement and compaction of the final wearing <br />20 course. The dimensions of the wedge must be as shown on the Drawings or as specified <br />21 by the Engineer. <br />22 <br />23 A tapered wedge cut must also be made at transitions to adjoining pavement surfaces <br />24 (meet lines) where butt joints are shown on the Drawings. Cut butt joints in a straight line <br />25 with vertical faces 2 inches or more in height, producing a smooth transition to the existing <br />26 adjoining pavement. <br />27 <br />28 After planing is complete, planed surfaces must be swept, cleaned, and if required by the <br />29 Contract, patched and preleveled. <br />30 <br />31 The Engineer may direct additional depth planing. Before performing this additional depth <br />32 planing, the Contractor must conduct a hidden metal in pavement detection survey as <br />33 specified in Section 5-04.3(14)A. <br />34 <br />35 5-04.3(14)A Pre-Planing Metal Detection Check <br />36 Before starting planing of pavements, and before any additional depth planing required by <br />37 the Engineer, the Contractor must conduct a physical survey of existing pavement to be <br />38 planed with equipment that can identify hidden metal objects. <br />39 <br />40 Should such metal be identified, promptly notify the Engineer. <br />41 <br />42 See Section 1-07.16(1) regarding the protection of survey monumentation that may be <br />43 hidden in pavement. <br />44 <br />45 The Contractor is solely responsible for any damage to equipment resulting from the <br />46 Contractors failure to conduct a pre-planing metal detection survey, or from the <br />47 Contractors failure to notify the Engineer of any hidden metal that is detected.
