5-O4.3(3)C Pavers <br /> II <br /> 2 HMA pavers shall be self-contained, power-propelled units, provided with an internally <br /> 3 heated vibratory screed and shall be capable of spreading and finishing courses of HMA <br /> I 4 plant mix material in lane widths required by the paving section shown in the Plans. <br /> 5 <br /> 6 The HMA paver shall be in good condition and shall have the most current equipment <br /> I 7 available from the manufacturer for the prevention of segregation of the HMA mixture <br /> 8 installed, in good condition, and in working order. The equipment certification shall list the <br /> 9 make, model, and year of the paver and any equipment that has been retrofitted. <br /> I 10 <br /> 11 The screed shall be operated in accordance with the manufacturer's recommendations and <br /> 12 shall effectively produce a finished surface of the required evenness and texture without <br /> I13 14 tearing, shoving, segregating, or gouging the mixture. A copy of the manufacturer's <br /> recommendations shall be provided upon request by the Contracting Agency. Extensions <br /> 15 will be allowed provided they produce the same results, including ride, density, and surface <br /> 16 texture as obtained by the primary screed. Extensions without augers and an internally <br /> I <br /> 17 heated vibratory screed shall not be used in the Traveled Way. <br /> 18 <br /> I 19 When specified in the Contract, reference lines for vertical control will be required. Lines <br /> 20 shall be placed on both outer edges of the Traveled Way of each Roadway. Horizontal <br /> 21 control utilizing the reference line will be permitted. The grade and slope for intermediate <br /> 22 lanes shall be controlled automatically from reference lines or by means of a mat <br /> 23 referencing device and a slope control device. When the finish of the grade prepared for <br /> 24 paving is superior to the established tolerances and when, in the opinion of the Engineer, <br /> 25 further improvement to the line, grade, cross-section, and smoothness can best be achieved <br /> I <br /> 26 without the use of the reference line, a mat referencing device may be substituted for the <br /> 27 reference line. Substitution of the device will be subject to the continued approval of the <br /> 28 Engineer. A joint matcher may be used subject to the approval of the Engineer. The <br /> I 29 reference line may be removed after the completion of the first course of HMA when <br /> 30 approved by the Engineer. Whenever the Engineer determines that any of these methods <br /> 31 are failing to provide the necessary vertical control, the reference lines will be reinstalled by <br /> I <br /> 32 the Contractor. <br /> 33 <br /> The Contractor shall furnish and install all pins, brackets, tensioning devices, wire, and <br /> 134 <br /> 35 accessories necessary for satisfactory operation of the automatic control equipment. <br /> 36 <br /> 37 If the paving machine in use is not providing the required finish, the Engineer may suspend <br /> I <br /> 38 Work as allowed by Section 1-08.6. Any cleaning or solvent type liquids spilled on the <br /> 39 pavement shall be thoroughly removed before paving proceeds. <br /> I 40 <br /> 41 5-04.3(3)D Material Transfer Device or Material Transfer Vehicle <br /> 42 A Material Transfer DeviceNehicle (MTDN) shall only be used with the Engineer's approval, <br /> I 43 unless otherwise required by the contract. <br /> 44 <br /> 45 Where an MTDN is required by the contract, the Engineer may approve paving without an <br /> 46 MTDN, at the request of the Contractor, The Engineer will determine if an equitable <br /> 47 adjustment in cost or time is due. <br /> 48 <br /> I 2020 PAVEMENT MAINTENANCE OVERLAY PAGE 47 OF 79 SPECIAL PROVISIONS <br /> WORK ORDER 3727 FEBRUARY 20,2020 <br />
