Unscheduled <br />9 transverse joints will be allowed, and the roller may pass over the unprotected end of the <br />10 freshly placed mixture only when the placement of the course must be discontinued for <br />11 such a length of time that the mixture will cool below compaction temperature. When the <br />12 Work is resumed, the previously compacted mixture shall be cut back to produce a <br />13 slightly beveled edge for the full thickness of the course. <br />14 <br />15 A temporary wedge of HMA constructed on a 20H:1V shall be constructed where a <br />16 transverse joint as a result of paving or planing is open to traffic. The HMA in the <br />17 temporary wedge shall be separated from the permanent HMA by strips of heavy <br />18 wrapping paper or other methods approved by the Engineer. The wrapping paper shall be <br />19 removed and the joint trimmed to a slightly beveled edge for the full thickness of the <br />20 course prior to resumption of paving. <br />21 <br />22 The material that is cut away shall be wasted and new mix shall be placed against the cut. <br />23 Rollers or tamping irons shall be used to seal the joint. <br />24 <br />25 5-04.3(12)A2 Longitudinal Joints <br />26 The longitudinal joint in any one course shall be offset from the course immediately below <br />27 by not more than 6 inches nor less than 2 inches. All longitudinal joints constructed in the <br />28 wearing course shall be located at a lane line or an edge line of the Traveled Way. A <br />29 notched wedge joint shall be constructed along all longitudinal joints in the wearing <br />30 surface of new HMA unless otherwise approved by the Engineer. The notched wedge <br />31 joint shall have a vertical edge of not less than the maximum aggregate size or more than <br />32 ‰ of the compacted lift thickness and then taper down on a slope not steeper than 4H:1V. <br />33 The sloped portion of the HMA notched wedge joint shall be uniformly compacted. <br />34 <br />35 5-04.3(12)B Bridge Paving Joint Seals <br />36 Bridge Paving Joint Seals shall be in accordance with Section 5-03. <br />37 <br />38 5-04.3(13) Surface Smoothness <br />39 The completed surface of all courses shall be of uniform texture, smooth, uniform as to <br />40 crown and grade, and free from defects of all kinds. The completed surface of the wearing <br />41 course shall not vary more than ⅛ inch from the lower edge of a 10-foot straightedge <br />42 placed on the surface parallel to the centerline. The transverse slope of the completed <br />43 surface of the wearing course shall vary not more than … inch in 10 feet from the rate of <br />44 transverse slope shown in the Plans. <br />45
