When the Work is 32 resumed, cut back the previously compacted HMA to produce a 33 slightly beveled edge for the full thickness of the course. 34 35 Construct a temporary wedge of HMA on a 50H:1V where a 36 transverse joint as a result of paving or planing is open to traffic. 37 Separate the HMA in the temporary wedge from the permanent HMA 38 upon which it is placed by strips of heavy wrapping paper or other 39 methods approved by the Engineer. Remove the wrapping paper and 40 trim the joint to a slightly beveled edge for the full thickness of the 41 course prior to resumption of paving. 42 43 Waste the material that is cut away and place new HMA against the 44 cut. Use rollers or tamping irons to seal the joint. 45 46 5-04.3(12)A2 Longitudinal Joints 47 Offset the longitudinal joint in any one course from the course 48 immediately below by not more than 6 inches nor less than 2 inches. 49 Locate all longitudinal joints constructed in the wearing course at a 50 lane line or an edge line of the Traveled Way. Construct a notched 51 wedge joint along all longitudinal joints in the wearing surface of new 52 HMA unless otherwise approved by the Engineer.
