CITY OF EVERETT SPECIAL PROVISIONS <br /> <br />3rd Ave Water Quality Facility Division 5 – SURFACE TREATMENTS September 12, 2024 <br />AND PAVEMENTS <br />WO No. – UP 3775 SP - 162 <br />5-04.3(12) Joints <br />5-04.3(12)A HMA Joints <br />5-04.3(12)A1 Transverse Joints <br />Conduct operations such that the placing of the top or wearing <br />course is a continuous operation or as close to continuous as <br />possible. Unscheduled transverse joints will be allowed and the <br />roller may pass over the unprotected end of the freshly laid mixture <br />only when the placement of the course must be discontinued for <br />such a length of time that the mixture will cool below compaction <br />temperature. When resuming the Work, cut back the previously <br />compacted mixture to produce a slightly beveled edge for the full <br />thickness of the course. <br />Construct a 20H:1V temporary wedge of HMA where a transverse <br />joint, as a result of paving or planing, is open to traffic. Separate the <br />HMA in the temporary wedge from the permanent HMA by strips of <br />heavy wrapping paper or other methods Engineer approves. <br />Remove the wrapping paper and the joint. Trim to a slightly beveled <br />edge for the full thickness of the course prior to resumption of <br />paving. <br />Remove and dispose of the cut away material and place new mix <br />against the cut. Use rollers or tamping irons to seal the joint. <br />5-04.3(12)A2 Longitudinal Joints <br />Offset the longitudinal joint in any one course from the course <br />immediately below by not more than 6 inches nor less than 2 inches. <br />Locate all wearing course longitudinal joints at a lane line or an edge <br />line of the Traveled Way. Construct a notched wedge joint along all <br />longitudinal joints in the wearing surface of new HMA unless <br />Engineer directs otherwise. Provide a notched wedge joint having a <br />vertical edge of not less than the maximum aggregate size or more <br />than 1/2 of the compacted lift thickness and then taper down on a <br />slope not steeper than 4H:1V. Uniformly compact the sloped portion <br />of the HMA notched wedge joint. <br />5-04.3(12)B Bridge Paving Joint Seals <br />5-04.3(12)B1 HMA Sawcut and Seal <br />Prior to placing HMA on the bridge deck, establish sawcut alignment <br />points at both ends of the bridge paving joint seals to be placed at <br />the bridge ends, and at interior joints within the bridge deck when <br />and where shown in the Plans. Establish the sawcut alignment <br />points in a manner that they remain functional for use in aligning the <br />sawcut after placing the overlay. <br />Submit a Type 1 Working Drawing consisting of the sealant <br />manufacturer’s application procedure. <br />Construct the bridge paving joint seal as specified in the Plans and <br />in accordance with the detail shown in the Standard Plans. <br />Construct the sawcut in accordance with the detail shown in the <br />Standard Plan. Construct the sawcut in accordance with Section 5- <br />05.3(8)B and the manufacturer’s application procedure.
