334 -5 . 7 . 3 Rate of Application : When using Type SP -9 . 5 (fine graded ) for leveling , do not allow the average spread of a layer to be less than 50 Ib/yd2 or more than 75 1 b/yd2 . The quantity of mix for leveling shown in the plans represents the average for the entire project ; however , the Contractor may vary the rate of application throughout the project as directed by the Engineer. When leveling in connection with base widening , the Engineer may require placing all the leveling mix prior to the widening operation . 334 -5 . 8 Compaction : For each paving or leveling train in operation , furnish a separate set of rollers , with their operators . When density testing for acceptance is required (Asphalt Work Category 3 ) , select equipment , sequence , and coverage of rolling to meet the specified density requirement . Regardless of the rolling procedure used , complete the final rolling before the surface temperature of the pavement drops to the extent that effective compaction may not be achieved or the rollers begin to damage the pavement . When density testing for acceptance is not required (Asphalt Work Categories 1 and 2 ) , use a rolling pattern approved by the Engineer . Use hand tamps or other satisfactory means to compact areas which are inaccessible to a roller , such as areas adjacent to curbs , headers , gutters , bridges , manholes , etc . 334-5 . 9 Joints . 334 -5 . 9 . 1 Transverse Joints : Construct smooth transverse joints , which are within 3/ 16 inch of a true longitudinal profile when measured with a 15 foot manual straightedge . 334 -5 . 9 . 2 Longitudinal Joints : For all layers of pavement except the leveling course , place each layer so that longitudinal construction joints are offset 6 to 12 inches laterally between successive layers . Do not construct longitudinal joints in the wheelpaths . The Engineer may waive these requirement where offsetting is not feasible due to the sequence of construction . 3344 . 10 Surface Requirements : Construct a smooth pavement with good surface texture and the proper cross - slope . 334 -5 . 10 . 1 Texture of the Finished Surface of Paving Layers : Produce a finished surface of uniform texture and compaction with no pulled , torn , raveled , crushed or loosened portions and free of segregation , bleeding , flushing , sand streaks , sand spots , or ripples . Correct any area of the surface that does not meet the foregoing requirements in accordance with 334- 5 . 10 . 4 . 3344 . 10 . 2 Cross Slope : Construct a pavement surface with cross slopes in compliance with the requirements of the Contract Documents . 334-5 . 10 . 3 Pavement Smoothness : Construct a smooth pavement meeting the requirements of this Specification . Furnish a 15 foot manual and a 15 foot rolling straightedge meeting the requirements of FM 5 - 509 . Make them available at the job site at all times during paving operations for Asphalt Work Category 3 and make them available upon request of the Engineer for Asphalt Work Categories 1 and 2 . 334 -5 . 10 . 3 . 1 Asphalt Work Category 3 : 334 -5 . 10 . 3 . 1 . 1 Acceptance Testing : Straightedge the final Type SP structural layer and friction course layer with a rolling straightedge . Test all pavement lanes where the width is constant using a rolling straightedge and document all deficiencies on a form approved by the Engineer . Notify the Engineer of the location and time of all straightedge testing a minimum of 48 hours before beginning testing . 37 Technical Specifications F :\Public Works\ENGINEERING DIVISION PROJECTS\0744-8th St-USI to 6th Ave\Admim\bid documents\0744 CONTRACT DOCUMENTS\Technical Specifications . doc
