The Engineer will determine if an equitable 8 adjustment in cost or time is due. 9 10 When used, the MTD/V shall mix the HMA after delivery by the hauling equipment and 11 prior to laydown by the paving machine. Mixing of the HMA shall be sufficient to obtain a 12 uniform temperature throughout the mixture. If a windrow elevator is used, the length of 13 the windrow may be limited in urban areas or through intersections, at the discretion of 14 the Engineer. 15 16 To be approved for use, an MTV: 17 18 1. Shall be self-propelled vehicle, separate from the hauling vehicle or paver. 19 2. Shall not be connected to the hauling vehicle or paver. 20 3. May accept HMA directly from the haul vehicle or pick up HMA from a windrow. 21 4. Shall mix the HMA after delivery by the hauling equipment and prior to 22 placement into the paving machine. 23 5. Shall mix the HMA sufficiently to obtain a uniform temperature throughout the 24 mixture. 25 26 To be approved for use, an MTD: 27 28 1. Shall be positively connected to the paver. 29 2. May accept HMA directly from the haul vehicle or pick up HMA from a windrow. 30 3. Shall mix the HMA after delivery by the hauling equipment and prior to 31 placement into the paving machine. 32 4. Shall mix the HMA sufficiently to obtain a uniform temperature throughout the 33 mixture. 34 35 5-04.3(3)E Rollers 36 Rollers shall be of the steel wheel, vibratory, oscillatory, or pneumatic tire type, in good 37 condition and capable of reversing without backlash. Operation of the roller shall be in 38 accordance with the manufacturers recommendations. When ordered by the Engineer for 39 any roller planned for use on the project, the Contractor shall provide a copy of the 40 manufacturers recommendation for the use of that roller for compaction of HMA. The 41 number and weight of rollers shall be sufficient to compact the mixture in compliance with 42 the requirements of Section 5-04.3(10). The use of equipment that results in crushing of 43 the aggregate will not be permitted. Rollers producing pickup, washboard, uneven 44 compaction of the surface, displacement of the mixture or other undesirable results shall 45 not be used. 46
