MATT THE MILLER’S; CARMEL CITY CENTER; SUITE 101 32 14 00 - CARMEL CITY CENTER Issue Date 03.26.12 UNIT PAVING MATT THE MILLER’S; CARMEL CITY CENTER; SUITE 101 B. Examine areas indicated to receive paving, with Installer present, for compliance with requirements for installation tolerances and other conditions affecting performance. Verify all dimensions of in-place and subsequent construction. 1. Proceed with installation only after unsatisfactory conditions have been corrected. 2. Where pavers are to be installed over waterproofing, examine waterproofing installation, with waterproofing Installer present, for protection from paving operations. Examine areas where waterproofing system is turned up or flashed against vertical surfaces and horizontal waterproofing. Proceed with installation only after protection is in place. 3.2 PREPARATION A. Clean concrete substrates to remove dirt, dust, debris, and loose particles. 3.3 INSTALLATION, GENERAL A. Do not use unit pavers with chips, cracks, voids, discolorations, and other defects that might be visible in finished work. B. Mix pavers from several pallets or cubes, as they are placed, to produce uniform blend of colors and textures. C. Cut unit pavers with motor-driven masonry saw equipment to provide clean, sharp, unchipped edges. Cut units to provide pattern indicated and to fit adjoining work neatly. Use full units without cutting where possible. Hammer cutting is not acceptable. 1. For concrete pavers, a block splitter may be used. D. Joint Pattern: As indicated on the drawings. E. Pavers over Waterproofing: Exercise care in placing pavers and setting materials over waterproofing so protection materials are not displaced and waterproofing is not punctured or otherwise damaged. Carefully replace protection materials that become displaced and arrange for repair of damaged waterproofing, at the paving contractor’s expense, before covering with paving. F. Expansion and Control Joints: Provide joint filler at locations and of widths indicated. Install joint filler before setting pavers. Make top of joint filler flush with top of pavers. G. Provide edge restraints as indicated. Install edge restraints before placing unit pavers. 1. Install edge restraints to comply with manufacturer's written instructions.

MATT THE MILLER’S; CARMEL CITY CENTER; SUITE 101 32 14 00 - CARMEL CITY CENTER Issue Date 03.26.12 UNIT PAVING MATT THE MILLER’S; CARMEL CITY CENTER; SUITE 101 B. Prepare for setting-bed placement by locating 3/4-inch- deep control bars approximately 11 feet apart and parallel to one another, to serve as guides for striking board. Adjust bars to sub- grades required for accurate setting of paving units to finished grades indicated. C. Setting bed material shall be delivered to site in trucks with steel bed linings that are clean and have not been lubricated with liquids detrimental to the material. 1. Truck traffic is prohibited on the precast concrete deck. Paving contractor to provide means acceptable to the general contractor, for the transportation of materials to the installation location. D. Place bituminous setting bed where indicated, in panels, by spreading bituminous material between control bars. Spread mix at a minimum temperature of 250 deg F. Strike setting bed smooth, firm, even, and not less than 3/4 inch thick. Add fresh bituminous material to low, porous spots after each pass of striking board. After each panel is completed, advance first control bar to next position in readiness for striking adjacent panels. Carefully fill depressions that remain after removing depth-control bars. 1. Roll setting bed with power roller to a nominal depth of 3/4 inch, or as required to meet finish grade elevations. Adjust thickness as necessary to allow accurate setting of unit pavers to finished grades indicated. Complete rolling before mix temperature cools to 185 deg F. E. Apply neoprene-modified asphalt adhesive to cold setting bed by squeegeeing or troweling to a uniform thickness of 1/16 inch. Proceed with setting of paving units only after adhesive is tacky and surface is dry to touch. F. Place pavers carefully by hand in straight courses, maintaining accurate alignment and uniform top surface. Protect newly laid pavers with plywood panels on which workers can stand. Advance protective panels as work progresses, but maintain protection in areas subject to continued movement of materials and equipment to avoid creating depressions or disrupting alignment of pavers. If additional leveling of paving is required, and before treating joints, roll paving with power roller after sufficient heat has built up in the surface from several days of hot weather. 1. Field cut patterns shown on Drawings. 2. Field cut pavers in accordance with manufacturer’s recommendations for methods, equipment and precautions. 3. Joints between pavers shall be between 1/16 inch and 1/8 inch wide. 4. Fill gaps at the edges of paved areas with cut pavers or edge units. Cut pavers to be placed along the edge, in such a manner that no segment is smaller than one quarter of a full paver. G. Joint Treatment: Place unit pavers with hand-tight joints. Fill joints with manufacturer’s recommended joint filler material, using manufacturer’s recommended joint filling technique. 1. Remove excess material after joints are filled. 2. Follow manufacturer’s written recommendations for the use of joint sand fillers and stabilizers referenced in 2.4.E of this specification section. 3.5 INSTALLATION TOLERANCES A. Base and Sub-base: 1. Base and sub-base shall be installed per design.

Remove and replace unit pavers that are loose, chipped, broken, stained, or otherwise damaged or that do not match adjoining units. Provide new units to match adjoining units and install in same manner as original units, with same joint treatment and with no evidence of replacement. B. Cleaning: 1. Keep bituminous-set pavers clean by regular sweeping. 2. Pressure-washing may be used to remove grease buildup, tire marks or other stains, as long as water –jet is not directed along joints. 3. Paint and gum may be removed by scrubbing with a stiff-bristled brush. C. Snow and Ice Removal: 1. Use de-icing or anti-icing chemicals with care.
