B. Bituminous Type Premolded Joint Filler: <br />1. Drive nails approximately 1 -foot 6 inches on center through the filler, prior to <br />installing, to provide anchorage embedment into the concrete during concrete <br />placement. <br />2. Secure premolded joint filler in forms before concrete is placed. <br />3. Install in walkways, at changes in direction, at intersections, at each side of driveway <br />entrances, and at 45 -foot intervals, maximum. <br />C. Pourable Joint Filler: <br />1. General: Install in accordance with the manufacturer's written instructions, except as <br />specified below: <br />a. Apply primer prior to pouring joint filler. <br />b. Fill entire joint above the water stop with joint filler as shown. <br />c. Use masking tape on top of slabs at sides of joints; clean spillage. Remove <br />masking tape afterwards. <br />2. Rubber Asphalt Type, Hot -Applied: <br />a. Heat filler material in a double -walled boiler. <br />b. Place filler in the joint by means of a nozzle from a portable pouring type <br />container to prevent spillage outside of the joint. <br />c. Begin pouring joint filler at the bottom of the horizontal joint and proceed <br />upwards in a manner that will preclude the possibility of trapping air in the joint. <br />3. Rubber Asphalt Type, Cold -Applied: Place cold -applied, two -component fillers in <br />accordance with manufacturer's written instructions. <br />4. Multicomponent Type for Potable Water Structures: Install in accordance with <br />manufacturer's written instructions. <br />D. Steel Expansion Joint Dowels: <br />1. Install coated and lubricated bars parallel to wall or slab surface and in true horizontal <br />position perpendicular to the joint in both plan and section view, so as to permit joint <br />to expand or contact without bending the dowels. <br />2. Secure dowels tightly in forms with rigid ties. <br />3. Install reinforcing steel in the concrete as shown to protect the concrete on each side <br />of the dowels and to resist any forces created by joint movement. <br />3.5 CONTROL JOINT INSTALLATION <br />A. Locate reinforcing and dowels as shown. <br />B. Install PVC water stop. Keep clean and free from coatings that would weaken the bond <br />with concrete. <br />Expansion, Construction and Control Joints February 2017 03251-8 <br />
