Remove organic, unstable or unconsolidated material from site, verify conformance of <br />subgrade preparation, compacted density and elevations to specified requirements. <br />2. Clean and re-use existing street brick pavers removed during site demolition. <br />Remaining pavers not used will be returned to the City. <br />3. Place Compacted Aggregate No. 53 to lines and grade. <br />4. Spread #12 limestone chips evenly over crushed stone base course and screed rails. <br />(Screed to 1 inch minimum thickness) <br />a. Do not spread #12 limestone chips beyond area to be covered by pavers the <br />same day. Prior to recommencement of work, remove, replace and re-screed <br />#12 limestone chips not covered with pavers the previous work day. <br />b. Do not disturb screeded setting bed. Re-screed disturbed setting bed. <br />4.Lay pavers by hand in pattern(s) matching existing layout. <br />a.Lay full pavers first. <br />b. Mix pavers from at least two pallets to produce uniform color blends. <br />5. Provide <br />116 inch to 3 16 inch wide joints between pavers. Adjust pavers to form straight <br />bond lines and appropriate joint widths. Maximum bond line variation shall be +-_ <br />inch over a 50 foot string line. <br />6. Fill gaps at paved area edges with cut pavers. <br />a.Cut pavers shall not be smaller than 1 3 (one-third) of a whole paver except wherepattern is to be maintained and a smaller piece is surrounded by a full paver <br />and concrete banding. <br />7. Do not permit traffic, including construction equipment, on pavers before initial <br />compaction and joint filling. Disturbed areas of pavers shall be taken up, the setting <br />bed re-screeded and pavers re-laid. <br />8. Vibrate pavers into setting bed using a high frequency/low-amplitude plate compactor <br />capable of 3,000 lbf to 5,000 lbf at a 75 to 100 Hz frequency. Protect pavers from <br />chipping during compaction by using a rubber matt, rubber rollers or other approved <br />materials placed over pavers. Do not compact within 6 feet of unrestrained edges. <br />Remove cracked or damaged pavers and replace with new units. <br />9. After pavers are fully settled and free from movement, simultaneously spread, sweep <br />and compact dry #12 limestone chips into joints until they are completely filled and <br />chips no longer falls into joints. <br />10. Protect areas not covered with cut and compacted pavers with waterproof covering <br />overnight.
