Drain excess release agent prior to filling hauling <br />equipment with HMA. Do NOT use petroleum derivatives or other coating material <br />that contaminate or alter the characteristics of the HMA. For live bed trucks, the <br />conveyer shall be in operation during the process of applying the release agent. <br />5-04.3(3)C Pavers <br />Provide HMA pavers that are self-contained, power-SURSHOOHGXQLWVZLWKDQௗLQWHUQDOO\ <br />heated vibratory screed and shall be capable of spreading and finishing courses of <br />HMA plant mix material in lane widths required by the paving section shown <br />LQௗWKHௗ3ODQV. <br />Provide HMA paver in good condition and have the most current equipment available <br />from the manufacturer for the prevention of segregation of the HMA mixture installed <br />in good condition and in working order. Provide equipment certification listing the <br />make, model, and year of the paver and note retrofitting of any equipment. <br />Operate the screed in accordance with the manufacturer’s recommendations and so <br />it effectively produces a finished surface of the required evenness and texture <br />ZLWKRXWWHDULQJVKRYLQJVHJUHJDWLQJRUJRXJLQJWKHPL[WXUH3URYLGHDௗFRS\RIWKH <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 screeGLQWKH7UDYHOHGௗ:D\ <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 may <br />be used subject to the approval of the Engineer. The reference line may be removed <br />after the completion of the first course of HMA when approved by the Engineer. <br />Whenever the Engineer determines that any of these methods are failing to provide <br />the necessary vertical control, the reference lines will be reinstalled by the <br />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.
