Excess release agent shall be drained <br />6 prior to filling hauling equipment with HMA. Petroleum derivatives or other coating <br />7 material that contaminate or alter the characteristics of the HMA shall not be used. For <br />8 live bed trucks, the conveyer shall be in operation during the process of applying the <br />9 release agent. <br />10 <br />11 5-04.3(3)C Pavers <br />12 HMA pavers shall be self-contained, power-propelled units, provided with 93X43+/*39&&' <br />13 heated vibratory screed and shall be capable of spreading and finishing courses of HMA <br />14 plant mix material in lane widths required by the paving section shown 43X+./X&935) <br />15 <br />16 The HMA paver shall be in good condition and shall have the most current equipment <br />17 available from the manufacturer for the prevention of segregation of the HMA mixture <br />18 installed, in good condition, and in working order. The equipment certification shall list the <br />19 make, model, and year of the paver and any equipment that has been retrofitted. <br />20 <br />21 The screed shall be operated in accordance with the manufacturers recommendations <br />22 and shall effectively produce a finished surface of the required evenness and texture <br />23 without tearing, shoving, segregating, or gouging the mixture. X816' of the <br />24 manufacturers recommendations shall be provided upon request by the Contracting <br />25 Agency. Extensions will be allowed provided they produce the same results, including <br />26 ride, density, and surface texture as obtained by the primary screed. Extensions without <br />27 augers and an internally heated vibratory screed shall not be used in the *9B/&/<X 9') <br />28 <br />29 When specified in the Contract, reference lines for vertical control will be required. Lines <br />30 shall be placed on both outer edges of the Traveled Way of each Roadway. Horizontal <br />31 control utilizing the reference line will be permitted. The grade and slope for intermediate <br />32 lanes shall be controlled automatically from reference lines or by means of a mat <br />33 referencing device and a slope control device. When the finish of the grade prepared for <br />34 paving is superior to the established tolerances and when, in the opinion of the Engineer, <br />35 further improvement to the line, grade, cross-section, and smoothness can best be <br />36 achieved without the use of the reference line, a mat referencing device may be <br />37 substituted for the reference line. Substitution of the device will be subject to the <br />38 continued approval of the Engineer. A joint matcher may be used subject to the approval <br />39 of the Engineer. The reference line may be removed after the completion of the first <br />40 course of HMA when approved by the Engineer. Whenever the Engineer determines that <br />41 any of these methods are failing to provide the necessary vertical control, the reference <br />42 lines will be reinstalled by the Contractor. <br />43 <br />44 The Contractor shall furnish and install all pins, brackets, tensioning devices, wire, and <br />45 accessories necessary for satisfactory operation of the automatic control equipment. <br />46 <br />47 If the paving machine in use is not providing the required finish, the Engineer may <br />48 suspend Work as allowed by Section 1-08.6. Any cleaning or solvent type liquids spilled <br />49 on the pavement shall be thoroughly removed before paving proceeds.
