Self-propelled vehicle, separate from the hauling vehicle or paver. <br />2. Not be connected to the hauling vehicle or paver. <br />3. May accept HMA directly from the haul vehicle or pick up HMA from a <br />windrow. <br />4. Ability to mix the HMA after delivery by the hauling equipment and prior to <br />placement into the paving machine. <br />5. Ability to mix the HMA sufficiently to obtain a uniform temperature throughout <br />the mixture. <br />To be approved for use, provide an MTD meeting the following: <br />1. Ability to be positively connected to the paver. <br />2. May accept HMA directly from the haul vehicle or pick up HMA from a <br />windrow. <br />3. Ability to mix the HMA after delivery by the hauling equipment and prior to <br />placement into the paving machine. <br />4. Ability to mix the HMA sufficiently to obtain a uniform temperature throughout <br />the mixture. <br />5-04.3(3)E Rollers <br />Provide vibratory, oscillatory steel wheel rollers, or pneumatic tire type rollers, in <br />good condition and capable of reversing without backlash. Operate roller in <br />accordance with the manufacturer’s recommendations. When ordered by the <br />Engineer for any roller planned for use on the project, provide a copy of the <br />manufacturer’s recommendation for the use of that roller for compaction of HMA. <br />Provide sufficient number and weight of rollers to compact the mixture in compliance <br />with the requirements of Section 5-04.3(10). The use of equipment that results in <br />crushing of the aggregate will not be permitted. Rollers producing pickup, <br />washboard, uneven compaction of the surface, displacement of the mixture or other <br />undesirable results will not be permitted. <br />5-04.3(4) Preparation of Existing Paved Surfaces <br />Bring any irregular existing pavement surface or old base surface to a uniform grade <br />and cross-section as shown on the Plans or approved by the Engineer. <br />Accomplish preleveling of uneven or broken surfaces over which HMA is to be <br />placed by using an asphalt paver, a motor patrol grader, or by hand raking, as <br />approved by the Engineer. <br />Provide compaction of preleveling HMA to the satisfaction of the Engineer and may <br />require the use of small steel wheel rollers, plate compactors, or pneumatic rollers <br />to avoid bridging across preleveled areas by the compaction equipment. Provide <br />Engineer approved compaction equipment used for the compaction of preleveling <br />HMA. <br />Clean the entire surface of the pavement before construction of HMA on an existing <br />paved surface. Entirely remove all fatty asphalt patches, grease drippings, and <br />other objectionable matter from the existing pavement. Thoroughly clean all <br />pavements or bituminous surfaces of dust, soil, pavement grindings, and other <br />foreign matter. Fill all holes and small depressions with an appropriate class of <br />HMA. Level and thoroughly compact the patched area surface. Obtain Engineer <br />approval of the surface prior to the application of tack coat or paving. <br />Apply an asphalt tack coat to all paved surfaces that HMA is to be placed or abutted; <br />except, that tack coat may be omitted from clean, newly paved surfaces at the <br />Engineer’s discretion. Uniformly apply tack coat to cover the existing pavement <br />with a thin film of residual asphalt free of streaks and bare spots at a rate between
