General: Comply with CRSI's "Manual of Standard Practice" for fabricating, placing, and <br />supporting reinforcement. <br />B. Clean reinforcement of loose rust and mill scale, earth, ice, or other bond - reducing materials. <br />C. Arrange, space, and securely tie bars and bar supports to hold reinforcement in position during <br />concrete placement. Maintain minimum cover to reinforcement. <br />D. Install welded wire reinforcement in lengths as long as practicable. Lap adjoining pieces at <br />least one full mesh, and lace splices with wire. Offset laps of adjoining widths to prevent <br />continuous laps in either direction. <br />3.5 JOINTS <br />A. General: Form construction, isolation, and contraction joints and tool edges true to line, with <br />faces perpendicular to surface plane of concrete. Construct transverse joints at right angles to <br />centerline unless otherwise indicated. <br />1. When joining existing paving, place transverse joints to align with previously placed <br />joints unless otherwise indicated. <br />B. Construction Joints: Set construction joints at side and end terminations of paving and at <br />locations where paving operations are stopped for more than one -half hour unless paving <br />terminates at isolation joints. <br />1. Continue steel reinforcement across construction joints unless otherwise indicated. Do <br />not continue reinforcement through sides of paving strips unless otherwise indicated. <br />2. Provide tie bars at sides of paving strips where indicated. <br />3. Butt Joints: Use bonding agent at joint locations where fresh concrete is placed against <br />hardened or partially hardened concrete surfaces. <br />4. Keyed Joints: Provide preformed keyway- section forms or bulkhead forms with keys <br />unless otherwise indicated. Embed keys at least 1 -1/2 inches (38 mm) into concrete. <br />5. Doweled Joints: Install dowel bars and support assemblies at joints where indicated. <br />Lubricate or coat with asphalt one -half of dowel length to prevent concrete bonding to <br />one side of joint. <br />C. Isolation Joints: Form isolation joints of preformed joint - filler strips abutting concrete curbs, <br />catch basins, manholes, inlets, structures, other fixed objects, and where indicated. <br />1. Locate expansion joints at intervals of 50 feet (15.25 m unless otherwise indicated. <br />2. Extend joint fillers full width and depth of joint. <br />3. Terminate joint filler not less than 1/2 inch (13 mm) or more than 1 inch (25 mm) below <br />finished surface if joint sealant is indicated. <br />4. Place top of joint filler flush with finished concrete surface if joint sealant is not <br />indicated. <br />5. Furnish joint fillers in one -piece lengths. Where more than one length is required, lace or <br />clip joint - filler sections together. <br />CONCRETE PAVING 321313 -7 <br />
