Minimum size of cut paver shall be half the width and length. No slivers will be accepted. Tolerances: Do not exceed 1/16-inch unit-to-unit offset from flush (lippage) For finished surface of paving finish surface shall not vary more than 1/8 inch in 24 inches and 1/4 inch in 10 feet from level, or indicated slope, as measured with a metal straight edge. AGGREGATE SETTING-BED PAVER APPLICATIONS: Excavation and installation of Gravel Borrow Base Course shall be in conformance with Section 150 of the Standard Specifications. Subgrade shall have been uniformly compacted to at least 95 percent of ASTM D 1557 laboratory density. Place Dense Graded Crushed Stone in conformance with Section 150 of the Standard Specifications and compact by tamping with plate vibrator and screed to depth required to allow setting of pavers. Place Metal Edge on compacted base. Where edging is required, edging shall be installed over the Base Course, not installed on top of the bedding layer. Spike rigid style edging using predrilled holes, with a maximum spacing of 12" between spikes. Spike placement may be placed through the back if needed. Connect additional sections of edging as needed Place sand setting bed course and screed to a thickness of 1 to 1-1/2 inches, taking care that moisture content remains constant and density is loose and constant until pavers are set and compacted. Lay the pavers in the pattern(s) as shown on the drawings. Maintain straight and uniform pattern lines. The pavers shall be hand placed paving units set with 1/16 inch joints. Mechanically vibrate pavers to uniform and true level to finish grade. Fill and sweep all joints with washed, clean concrete sand. Clean all paver surfaces. Vibrate pavers into setting bed course with a low-amplitude plate vibrator capable of a to 5000-lbf (16- to 22- kn) compaction force at 80 to 90 Hz. Perform at least three passes across paving with vibrator. Vibrate under the following conditions: After edge pavers are installed and there is a completed surface or before surface is exposed to rain. 39

40 Before ending each day's work, fully compact installed concrete pavers to within 36 inches of the laying face. Cover open layers with nonstaining plastic sheets overlapped 48 inches on each side of the laying face to protect it from rain. Spread dry sand and fill joints immediately after vibrating pavers into leveling course. Vibrate pavers and add sand until joints are completely filled, then remove excess sand. After initial joint sand application is watered in and pavers are completely dry, a second application of sand shall be swept into the joints to fill any remaining voids. After all sand has been removed from the paver surface the joints shall be watered thoroughly. This process shall be repeated until all joints are filled. Clean all paver surfaces as needed. Do not allow traffic on installed pavers until sand has been vibrated into joints. Repeat joint-filling process 30 days later. BITUMINOUS SETTING-BED APPLICATIONS: CONCRETE BASE SLAB INSTALLATION: Concrete base slab shall be laid in accordance with the plans, details and sections. Concrete base course placement, testing, reinforcing and protection and form work shall be as specified in Section 901 CEMENT CONCRETE MASONRY, except as modified below. Concrete shall have a rollerbug float finish. No spray or curing compounds shall be used in construction of concrete base course. Place expansion joints at twenty feet on center or as otherwise directed on the Drawings. Joints shall reflect full depth through concrete base course. Concrete base shall be placed in one (1) course, to full depth, as detailed on the Plans. No traffic of any kind shall be allowed to pass over the newly installed surface until it has had time to set. Twentyfour (24) hours will be considered sufficient time for the pavement to set in most cases, but this period may be extended by the Engineer as required by weather or other reasons. All forms shall be joined neatly and tightly, shall be set true to line and grade, well staked and braced, and shall have uniform bearings throughout their length. All forms and stakes shall be removed before placing loam or backfill. Adequate protection shall be where temperatures of forty degrees F or lower occur during placing of concrete and during the early curing period. The minimum temperature of fresh concrete after placing and for the first three days shall be maintained above fifty-five degrees F. In addition to the above requirements, an additional three days of protection from freezing shall be maintained. Expansion joints shall be placed as indicated on the Detailed Drawings where pavement meets the curbing, structures, including light bases, hydrants, and where new pavement shall abut existing pavement as shown on the Plans. Install foam filler for expansion joints twenty feet on center and as indicated on the Plans. Joint alignment shall be straight and true. Expansion joints in concrete base course shall be aligned to match the required pattern of expansion joints in the finished pavement surface. After floating the concrete off to the desired elevation, apply a pattern to the surface using a rollerbug or similar tool that shall provide a roughened texture to the concrete without affecting the finish grade. Prior to installation of bituminous setting bed and setting pavers, the concrete base slab shall be cured for a minimum of six days. The surface shall be wetted or otherwise kept moist through the use of a polyethylene film or wetted burlap. The surface shall be protected from traffic or other disturbances during the curing period. 40

41 Contractor shall not begin installation of pavers until the Engineer has accepted finish grade of pavement base. Concrete base shall be inspected to insure that the finished grades are correct. If in the opinion of the Engineer finish grades are not correct, the Contractor shall vary the thickness of the stone dust setting bed for pavers as necessary to insure positive drainage of the finished surface. BITUMINOUS SETTING BED INSTALLATION: Concrete Base Preparation: Do any cleaning necessary to cement concrete base to provide a clean base surface, free from oil, grease, other impurities, or loose or friable particles. As indicated on the Drawings where pavers meet lawn areas, install metal paver edge as indicated on the Drawings and in accordance with manufacturer s recommendations. Apply primer to concrete slab immediately before placing setting bed. Prepare for setting-bed placement by locating 3/4-inch- (19-mm-) deep control bars approximately 11 feet (3.3 m) apart and parallel to one another, to serve as guides for striking board. Adjust bars to subgrades required for accurate setting of paving units to finished grades indicated. Place bituminous setting bed where indicated, in panels, by spreading bituminous material between control bars. Strike setting bed smooth, firm, even, and not less than 3/4 inch (19 mm) 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. Roll setting bed with power roller to a nominal depth of 3/4 inch (19 mm) while still hot. Adjust thickness as necessary to allow accurate setting of unit pavers to finished grades indicated. A coating of two percent (2%) neoprene-modified asphalt adhesive shall be applied by mopping, squeezing, or troweling over the top surface of the bituminous setting bed. Adhesive shall be applied to provide a complete bond under all pavers. If it is trowelled, the trowel shall be serrated with serrations not to exceed 1/16". Proceed with setting of paving units only after adhesive is dry to the touch. PAVER INSTALLATION No pavers shall be laid in inclement weather or when the temperature is 36 degrees F., and dropping, nor shall any work be done on rising temperatures until the temperature reaches 32 degrees F. Frozen materials shall not be used. 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. Joint Treatment: Place unit pavers with hand-tight joints. Fill joints with sand by sweeping over paved surface until joints are filled. REPAIR, POINTING, CLEANING, AND PROTECTION: 41

42 Remove and replace unit pavers that are loose, chipped, broken, stained, or otherwise damaged or that do not match adjoining units as intended. 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.
