Edgewater Creek Bridge Replacement November 2023 101 The contractor shall provide an environmentally benign means to prevent the HMA 1 mixture from adhering to the hauling equipment. Excess release agent shall be drained 2 prior to filling hauling equipment with HMA. Petroleum derivatives or other coating 3 material that contaminate or alter the characteristics of the HMA shall not be used. For 4 live bed trucks, the conveyer shall be in operation during the process of applying the 5 release agent. 6 7 5-04.3(3)C Pavers 8 HMA pavers shall be self-contained, power-propelled units, provided with an internally 9 heated vibratory screed and shall be capable of spreading and finishing courses of HMA 10 plant mix material in lane widths required by the paving section shown in the Plans. 11 12 The HMA paver shall be in good condition and shall have the most current equipment 13 available from the manufacturer for the prevention of segregation of the HMA mixture 14 installed, in good condition, and in working order. The equipment certification shall list 15 the make, model, and year of the paver and any equipment that has been retrofitted. 16 17 The screed shall be operated in accordance with the manufacturer’s recommendations 18 and shall effectively produce a finished surface of the required evenness and texture 19 without tearing, shoving, segregating, or gouging the mixture. A copy of the 20 manufacturer’s recommendations shall be provided upon request by the Contracting 21 Agency. Extensions will be allowed provided they produce the same results, including 22 ride, density, and surface texture as obtained by the primary screed. Extensions without 23 augers and an internally heated vibratory screed shall not be used in the Traveled Way. 24 25 When specified in the Contract, reference lines for vertical control will be required. Lines 26 shall be placed on both outer edges of the Traveled Way of each Roadway. Horizontal 27 control utilizing the reference line will be permitted. The grade and slope for intermediate 28 lanes shall be controlled automatically from reference lines or by means of a mat 29 referencing device and a slope control device. When the finish of the grade prepared for 30 paving is superior to the established tolerances and when, in the opinion of the Engineer, 31 further improvement to the line, grade, cross-section, and smoothness can best be 32 achieved without the use of the reference line, a mat referencing device may be 33 substituted for the reference line. Substitution of the device will be subject to the 34 continued approval of the Engineer. A joint matcher may be used subject to the approval 35 of the Engineer. The reference line may be removed after the completion of the first 36 course of HMA when approved by the Engineer. Whenever the Engineer determines that 37 any of these methods are failing to provide the necessary vertical control, the reference 38 lines will be reinstalled by the Contractor. 39 40 The Contractor shall furnish and install all pins, brackets, tensioning devices, wire, and 41 accessories necessary for satisfactory operation of the automatic control equipment. 42 43 If the paving machine in use is not providing the required finish, the Engineer may 44 suspend Work as allowed by Section 1-08.6. Any cleaning or solvent type liquids spilled 45 on the pavement shall be thoroughly removed before paving proceeds. 46 47 5-04.3(3)D Material Transfer Device or Material Transfer Vehicle 48
