<br /> <br />ASPHALT PAVING & SURFACING 02 5500-7 <br />D. Asphalt concrete shall be rolled such that compaction after rolling shall be 95% <br />of the density obtained with the California Test 304, Method of Preparation of <br />HMA for Test Specimens and 308, Method of Test for Determining Bulk <br />Specific Gravity and Density of Compacted Hot Mix Asphalt. Field density tests <br />may be conducted by the Engineer to confirm density using the California Test <br />375, Determining the In-Place Density and Relative Compaction of Hot Mix <br />Asphalt Pavement Using Nuclear Gages. <br />E. Failure to meet the specified density may require credits back to the City for <br />non- conformance. <br />3.05 ADJUST MANHOLES, VALVES, AND MONUMENT COVERS <br />A. Existing manholes, lampholes, valve and monument covers, or other such <br />structures in the line of the work shall be adjusted to conform with the new <br />grade after completion of paving operations. <br />B. The box will be adjusted by removing the existing concrete pad and pouring a <br />new pad of concrete. <br />C. The concrete collar shall be circular and shall be covered with a minimum of <br />two inches of asphalt concrete to blend in with the adjacent surfacing. <br />D. Extension rings will not be acceptable. Contractor shall be responsible for <br />preserving the survey point in its original position. <br />3.06 ASPHALT PLANING <br />A. The depth, width, and shape of the cut shall be as shown on the plans by a <br />project-specific detail, or if there is no project-specific detail, as shown on City <br />Standard Engineering Detail A-6. <br />B. Asphalt planing operations shall provide a final cut resulting in a uniform <br />surface conforming to the typical cross sections, and be performed without <br />damage to the surfacing to remain in place. <br />C. For overlay, plane as necessary to allow a minimum overlay of two (2) inch to <br />new elevations. <br />D. Where transverse joints are planed in the pavement at conform lines no drop- <br />off shall remain between the existing pavement and the planed area when the <br />pavement is opened to public traffic. If asphalt concrete has not been placed to <br />the level of existing pavement before the pavement is to be opened to public <br />traffic a temporary asphalt concrete taper shall be constructed. Asphalt <br />concrete for temporary tapers shall be placed to the level of the existing <br />pavement and tapered on a slope of 1:30 (Vertical:Horizontal) or flatter to the <br />level of the planed area. <br />E. The contractor will be held responsible for any and all damage to trees, plants, <br />and shrubs caused by the grinding operation and shall satisfactorily replace <br />with new material or correct any damage. <br />F. Ground asphalt concrete shall be removed from the job site and disposed of <br />7.A. - Page 16 of 121 <br />22
