CITY OF EVERETT SPECIAL PROVISIONS <br /> <br />3rd Ave Water Quality Facility Division 5 – SURFACE TREATMENTS September 12, 2024 <br />AND PAVEMENTS <br />WO No. – UP 3775 SP - 152 <br />Mix the MTD/V when used with the HMA after delivery by the hauling equipment <br />and prior to laydown by the paving machine. Sufficiently mix the HMA to obtain a <br />uniform temperature throughout the mixture. The length of the windrow for <br />windrow elevator may be limited in urban areas or through intersections at the <br />discretion of the Engineer. <br />To be approved for use, provide an MTV meeting the following: <br />1. 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 <br />throughout 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 <br />throughout 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 <br />compliance with the requirements of Section 5-04.3(10). The use of equipment <br />that results in crushing of the aggregate will not be permitted. Rollers producing <br />pickup, washboard, uneven compaction of the surface, displacement of the <br />mixture or other 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 <br />grade 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 <br />may require the use of small steel wheel rollers, plate compactors, or pneumatic <br />rollers to avoid bridging across preleveled areas by the compaction equipment. <br />Provide Engineer approved compaction equipment used for the compaction of <br />preleveling HMA. <br />Clean the entire surface of the pavement before construction of HMA on an <br />existing paved surface. Entirely remove all fatty asphalt patches, grease <br />drippings, and other objectionable matter from the existing pavement. Thoroughly <br />clean all pavements or bituminous surfaces of dust, soil, pavement grindings, and
