          3.3INSTALLATION
 
          A.Install in accordance with manufacturer's instructions, approved submittals and in proper relationship with adjacent construction.
          1.Provide edge restraints as indicated.
          2.Provide separation geotextile on bottom and sides of prepared subgrade. Secure in place to prevent wrinkles and folds. Overlap edges minimum of 18 inches (450 mm) in direction of drainage.
          3.Provide base and subbase indicated. Compact and provide to tolerances as recommended by paver manufacturer.
          4.Provide and spread setting bed as recommended by paver manufacturer.
          5.Mix concrete pavers from a minimum of three bundles to produce uniform blend of colors and textures.
          6.Lay concrete pavers to pattern indicated.
          7.Provide spacing recommended by paver manufacturer.
          8.Cut pavers as recommended by manufacturer.
          9.Vibrate pavers to leveling course as recommended by manufacturer.
          10.Spread joint material and vibrate until joints are completely filled.
          ** NOTE TO SPECIFIER ** Delete if sealer is not required.
          11.Apply sealer in accordance with sealer and paver manufacturer recommendations after cleaning products.
 
          3.4FIELD QUALITY CONTROL
 
          A.Verify final elevations for conformance to the Drawings.
          1.Prevent finished grade elevations from deviating more than 3/8 inch (10 mm) under a 10 foot (3 m) straightedge or indicated slope.
          2.No greater than 1/32 inch (0.8 mm) difference in height between pavers and adjacent paved surfaces.
 
          3.5CLEANING AND PROTECTION
 
          A.Prevent traffic on pavers until joint material is vibrated into joints.
 
          B.Clean products in accordance with the manufacturers recommendations.
 
          C.Touch-up, repair or replace damaged products before Substantial Completion.
          ** NOTE TO SPECIFIER ** Article below is for permeable paver installations. Delete if not required.
 
          3.6MAINTENANCE
 
          A.Remove all debris from joint and provide additional Permeable Joint Aggregate material after 120 days and before 150 days after date of Substantial Completion.
 
          B.Fill Permeable Joint Aggregate material full to the lip of the paver.
          ** NOTE TO SPECIFIER ** Delete Paragraph below if annual maintenance is not included in Contract.
 
          C.Annual Maintenance:
          1.Annually inspect Permeable Joint Aggregate material for areas clogged with debris.
          2.Vacuum or sweep as necessary to restore surface infiltration.
          3.Replenish removed Permeable Joint Aggregate material with clean aggregate material flush to paver lip.
          4.Sweep excess material from paver surface.
