2025 PAVEMENT MAINTENANCE OVERLAY SPECIAL PROVISIONS PW# 3830 SP-63 March 26, 2025 5-04.3(12)A1 Transverse Joints 1 The Contractor shall conduct operations such that the placing of the top or wearing 2 course is a continuous operation or as close to continuous as possible. Unscheduled 3 transverse joints will be allowed, and the roller may pass over the unprotected end of the 4 freshly laid mixture only when the placement of the course must be discontinued for such 5 a length of time that the mixture will cool below compaction temperature. When the Work 6 is resumed, the previously compacted mixture shall be cut back to produce a slightly 7 beveled edge for the full thickness of the course. 8 9 A temporary wedge of HMA constructed on a 20H:1V shall be constructed where a 10 transverse joint as a result of paving or planing is open to traffic. The HMA in the 11 temporary wedge shall be separated from the permanent HMA by strips of heavy 12 wrapping paper or other methods approved by the Engineer. The wrapping paper shall 13 be removed and the joint trimmed to a slightly beveled edge for the full thickness of the 14 course prior to resumption of paving. 15 16 The material that is cut away shall be wasted and new mix shall be laid against the cut. 17 Rollers or tamping irons shall be used to seal the joint. 18 19 5-04.3(12)A2 Longitudinal Joints 20 The longitudinal joint in any one course shall be offset from the course immediately 21 below by not more than 6 inches nor less than 2 inches. All longitudinal joints 22 constructed in the wearing course shall be located at a lane line or an edge line of the 23 Traveled Way. A notched wedge joint shall be constructed along all longitudinal joints in 24 the wearing surface of new HMA unless otherwise approved by the Engineer. The 25 notched wedge joint shall have a vertical edge of not less than the maximum aggregate 26 size or more than ½ of the compacted lift thickness and then taper down on a slope not 27 steeper than 4H:1V. The sloped portion of the HMA notched wedge joint shall be 28 uniformly compacted. 29 30 5-04.3(12)B Bridge Paving Joint Seals 31 Bridge Paving Joint Seals shall be in accordance with Section 5-03. 32 33 5-04.3(13) Surface Smoothness 34 The completed surface of all courses shall be of uniform texture, smooth, uniform as to 35 crown and grade, and free from defects of all kinds. The completed surface of the 36 wearing course shall not vary more than ⅛ inch from the lower edge of a 10-foot 37 straightedge placed on the surface parallel to the centerline. The transverse slope of the 38 completed surface of the wearing course shall vary not more than ¼ inch in 10 feet from 39 the rate of transverse slope shown in the Plans. 40 41 When deviations in excess of the above tolerances are found that result from a high 42 place in the HMA, the pavement surface shall be corrected by one of the 43 following methods: 44 45 1. Removal of material from high places by grinding with an approved grinding 46 machine, or 47 48
