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 - 163 <br />5-04.3(3)C Pavers <br />Provide HMA pavers that are self-contained, power-propelled units, with <br />an internally heated vibratory screed and shall be capable of spreading and finishing <br />courses of HMA plant mix material in lane widths required by the paving section <br />shown in the Plans. <br />Provide HMA paver in good condition and have the most current equipment <br />available from the manufacturer for the prevention of segregation of the HMA <br />mixture installed in good condition and in working order. Provide equipment <br />certification listing the make, model, and year of the paver and note retrofitting of <br />any equipment. <br />Operate the screed in accordance with the manufacturer’s recommendations and <br />so it effectively produces a finished surface of the required evenness and texture <br />without tearing, shoving, segregating, or gouging the mixture. Provide a copy of the <br />manufacturer’s recommendations upon City’s request. Extensions producing the <br />same results, including ride, density, and surface texture as obtained by the primary <br />screed will be allowed. Do NOT use extensions without augers and an internally <br />heated vibratory screed in the Traveled Way. <br />When specified in the Contract, reference lines for vertical control will be required. <br />Place lines on both outer edges of the Traveled Way of each Roadway. Horizontal <br />control utilizing the reference line will be permitted. Control the grade and slope for <br />intermediate lanes automatically from reference lines or by means of a mat <br />referencing device and a slope control device. When the finish of the grade <br />prepared for paving is superior to the established tolerances and when, in the <br />opinion of the Engineer, further improvement to the line, grade, cross-section, and <br />smoothness can best be achieved without the use of the reference line, a mat <br />referencing device may be substituted for the reference line. Substitution of the <br />device will be subject to the continued approval of the Engineer. A joint matcher <br />may be used subject to the approval of the Engineer. The reference line may be <br />removed after the completion of the first course of HMA when approved by the <br />Engineer. Whenever the Engineer determines that any of these methods are failing <br />to provide the necessary vertical control, the reference lines will be reinstalled by <br />the Contractor. <br />Furnish and install all pins, brackets, tensioning devices, wire, and accessories <br />necessary for satisfactory operation of the automatic control equipment. <br />If the paving machine in use is not providing the required finish, the Engineer may <br />suspend Work as allowed by Section 1-08.6. Thoroughly remove any cleaning or <br />solvent type liquids spilled on the pavement before paving proceeds. <br />5-04.3(3)D Material Transfer Device or Material Transfer Vehicle <br />Provide a Material Transfer Device/Vehicle (MTD/V) with the Engineer’s approval, <br />unless otherwise required by the Contract. <br />Where an MTD/V is required by the contract, the Engineer may approve paving <br />without an MTD/V, at the Contractor’s request. The Engineer will determine if an <br />equitable adjustment in cost or time is due. <br />Mix the MTD/V when used with the HMA after delivery by the hauling equipment <br />and prior to laydown by the paving machine. Sufficiently mix the HMA to obtain a <br />uniform temperature throughout the mixture. The length of the windrow for windrow <br />elevator may be limited in urban areas or through intersections at the discretion of <br />the Engineer. <br />To be approved for use, provide an MTV meeting the following:
