5. Compacting bedding and joint sand: <br /> a) Use a low amplitude vibrator capable of 5,000 foot-pounds with 7- <br /> 100 hZ frequencies to vibrate and compact brick pavers into <br /> bedding sand. <br /> b) Vibrate the pavers, sweeping dry joint sand into the joints and <br /> vibrating, until the joints are full. Do not vibrate within 3 feet of the <br /> unrestrained edges of brick pavers. <br /> c) At the end of each day, all work within 3 feet of the laying face <br /> must be left fully compacted, with sand-filled joints. <br /> d) Sweep off the excess sand. <br /> 6. Leave a final surface elevation of brick pavers of 1/8 to '/4 inch above <br /> adjacent drainage inlets, concrete collars or channels. <br /> 7. Do not permit the final surface of pavers to deviate more than 3/8 inch <br /> under a 10 foot long straightedge, or more than 1/8 inch between <br /> adjacent pavers. <br /> END OF SECTION <br /> 08/12 02514-2 11-4179 <br />
