A. Checker Block:
Pavers shall be manufactured of licensed for manufacture by the Hasting Pavement Company, Inc., 640 Muncy Avenue, Lindenhurst, NY 11757. The pavers shall be 24" square and 4" deep. They shall be made in a waffle-like pattern with sixteen hubs, each 4" in height. They shall be fabricated of Portland Cement Type 11 or 111 fine and course aggregates (ASTM C-33-61) utilizing a steel mesh-6"/6' x 8/8 gauge with an air-entraining agent between 4%-6% (ASTM-C-173) achieving a concrete strength of 5,000 psi at 28 days
(ASTM C-39-49) and a maximum water absorption of 5% (ASTM C-97). |
A. Installation Procedures:
Base for Pavers shall be either undisturbed earth or fill compacted to 95% maximum dry density as determined by the Modified Proctor Test ASTM D- 1557-64 + (plus 4% or minus 2% optimum moisture). Remove from the setting bed rock or other materials which would create uneven bearing. Place sand in a
2" compacted layer over the base to present a true and even grade over entire area to receive pavers.
Set pavers and line up to abut.
B: Void Filler (By Others): Thoroughly mix fertilizer and other additives with the topsoil and spread loosely to fill void in Pavers. Water with a mist spray to settle. Add additional topsoil mix to bring the topsoil flush with top of the Paver. Seed at slightly less than normal rate and mulch. When grass is 2 1/2" high, cut to 13/4". Crushed gravel can be substituted for seeding and topsoil. |
