I 1 5-01.3(1)A1 Concrete Patching Materials I 2 In this section, each reference to "9-20" is revised to read "9-20.1". 3 4 5-01.3(4) Replace Cement Concrete Panel 5 This section's content is deleted and replaced with the following new subsections: 6 7 5-01.3(4)A General 8 Curing, cold weather work, concrete pavement construction in adjacent lines, and 9 protection of pavement shall meet the requirements of Section 5-05.3(13) through Section 10 5-05.3(15). The Contractor, at no cost to the Contracting Agency, shall repair any damage111 11 to existing pavement caused by the Contractor's operations. 12 13 5-01.3(4)B Sawing and Dimensional Requirements 14 Concrete slabs to be replaced as shown in the Plans or staked by the Engineer shall be at 15 least 6.0 feet long and full width of an existing pavement panel. The portion of the panel to 16 remain in place shall have a minimum dimension of 6 feet in length and full panel width; 17 otherwise the entire panel shall be removed and replaced. There shall be no new joints 18 closer than 3.0 feet to an existing transverse joint or crack. A vertical full depth saw cut is 19 required along all longitudinal joints and at transverse locations and, unless the Engineer 20 allows otherwise, an additional vertical full depth relief saw cut located 12 to 18 inches from 21 and parallel to the initial longitudinal and transverse saw cut locations is also required. 22 Removal of existing cement concrete pavement shall not cause damage to adjacent slabs 23 that are to remain in place. In areas that will be ground, slab replacements shall be 24 performed prior to pavement grinding. 25 26 Side forms shall meet the requirements of Section 5-05.3(7)B whenever a sawed full depth 27 vertical face cannot be maintained. 28 29 5-01.3(4)C Dowel Bars and Tie Bars 30 For the half of a dowel bar or tie bar placed in fresh concrete, comply with the requirements 31 of Section 5-05. 32 33 For the half of a dowel bar or tie bar placed in hardened concrete, comply with the 34 Standard Plans and the following. 35 36 After drilling, secure dowel bars and tie bars into the existing pavement with either an 37 epoxy bonding agent Type I or IV as specified in Section 9-26.1, or a grout Type 2 for non- 38 shrink applications as specified in Section 9-20.3. 39 40 Dowel bars shall be placed at the mid depth of the concrete slab, centered over the 41 transverse joint, and parallel to the centerline and to the roadway surface, within the 42 tolerances in the table below. Dowel bars may be adjusted to avoid contact with existing 43 dowel bars in the transverse joint at bridge approach slabs or existing panels provided the 44 adjusted dowel bars meet the tolerances below. 45 46 Tie bars shall be placed at the mid depth of the concrete slab, centered over the joint, 47 perpendicular to centerline, and parallel to the roadway surface, within the tolerances in the 48 table below. The horizontal position of tie bars may be adjusted to avoid contact with 49 existing tie bars in the longitudinal joint where panel replacement takes place, provided the 50 adjusted tie bars meet the tolerances below. 51 1 City of Everett Page AM-12 Amendments Everett Downtown Streetscape Improvement March 22, 2019
