CITY OF EVERETT SPECIAL PROVISIONS <br /> <br />Beverly Lake Water Quality Retrofit Division 5 – SURFACE TREATMENTS August 2023 <br /> <br />AND PAVEMENTS <br />WO No. – UP3745 SP - 175 <br />the lower edge of a 10-foot straightedge placed on the surface parallel to the <br />centerline. Provide the transverse slope of the wearing course completed <br />surface that does NOT vary more than 1/4 inch in 10 feet from the rate of <br />transverse slope shown in the Plans. <br />When deviations in excess of the above tolerances are found that result from <br />a high place in the HMA, correct the pavement surface using one of the <br />following methods: <br />a. Removal of material from high places by grinding with an approved <br />grinding machine, or <br />b. Removal and replacement of the wearing course of HMA, or <br />c. By other method approved by the Engineer. <br />Carry out defect correction until there are no deviations anywhere greater than <br />the allowable tolerances. <br />City will accept with a price adjustment deviations in excess of the above <br />tolerances that result from a low place in the HMA and deviations resulting from <br />a high place where corrective action, in the opinion of the Engineer, will not <br />produce satisfactory results. The Engineer will deduct from monies due or that <br />may become due to the Contractor the sum of $500.00 for each and every <br />section of single traffic lane 100 feet in length in which any excessive deviations <br />described above are found. <br />When utility appurtenances such as manhole covers and valve boxes are <br />located in the traveled way, adjust the utility appurtenances to the finished <br />grade prior to paving. If Contractor requests, Engineer may waive this <br />requirement or when the adjustment details provided in the project plan or <br />specifications call for utility appurtenance adjustments after the completion of <br />paving. <br />Include utility appurtenance adjustment discussions in the Pre-Paving planning <br />(5-04.3(14)B3). Submit a written request to waive this requirement to the <br />Engineer prior to the start of paving. <br />5-04.3(14) Planing (Milling) Bituminous Pavement <br />Engineer must approve the planing plan. Hold, with Engineer, a pre-planing <br />meeting prior to the start of any planing. See Section 5-04.3(14)B2 for <br />information on planing submittals. <br />Refer to the Plans for locations of existing surfacing being planed. <br />Where planing an existing pavement is specified in the Contract Documents, <br />remove existing surfacing material and reshape the surface to remove <br />irregularities. The finished product must be a prepared surface acceptable for <br />receiving an HMA overlay. <br />Use the cold milling method for planing unless otherwise specified in the <br />Contract. Do NOT use the planer on the final wearing course of new HMA. <br />Conduct planing operations in a manner that does not tear, break, burn, or <br />otherwise damage the surface to remain. The finished planed surface must be <br />slightly grooved or roughened and must be free from gouges, deep grooves, <br />ridges, or other imperfections. Repair any damage to the surface planing <br />equipment makes using an Engineer approved method. <br />Repair or replace any metal castings and other surface improvements <br />damaged by planing as confirmed by the Engineer.
