Excess release agent shall be drained 6 prior to filling hauling equipment with HMA. Petroleum derivatives or other coating 7 material that contaminate or alter the characteristics of the HMA shall not be used. For I8 live bed trucks, the conveyer shall be in operation during the process of applying the 9 release agent. ' 10 11 5-04.3(3)C Pavers 12 HMA pavers shall be self-contained, power-propelled units, provided with an internally I 13 14 heated vibratory screed and shall be capable of spreading and finishing courses of HMA plant mix material in lane widths required by the paving section shown in the Plans. 15 I 16 The HMA paver shall be in good condition and shall have the most current equipment 17 available from the manufacturer for the prevention of segregation of the HMA mixture 18 installed, in good condition, and in working order. The equipment certification shall list I19 the make, model, and year of the paver and any equipment that has been retrofitted. 20 21 The screed shall be operated in accordance with the manufacturer's recommendations I 22 and shall effectively produce a finished surface of the required evenness and texture 23 without tearing, shoving, segregating, or gouging the mixture. A copy of the 24 manufacturer's recommendations shall be provided upon request by the Contracting I 25 26 Agency.

When the finish of the grade prepared for I 34 35 paving is superior to the established tolerances and when, in the opinion of the Engineer, further improvement to the line, grade, cross-section, and smoothness can best be 36 achieved without the use of the reference line, a mat referencing device may be I 37 substituted for the reference line. Substitution of the device will be subject to the 38 continued approval of the Engineer. A joint matcher may be used subject to the approval 39 of the Engineer. The reference line may be removed after the completion of the first 40 course of HMA when approved by the Engineer. Whenever the Engineer determines that I 41 any of these methods are failing to provide the necessary vertical control, the reference 42 lines will be reinstalled by the Contractor. 43 I 44 The Contractor shall furnish and install all pins, brackets, tensioning devices, wire, and 45 accessories necessary for satisfactory operation of the automatic control equipment.
