Do not use joint sand for bedding sand.
526-2.5 Bedding and Joint Grouts: A suitable grout, in thickness specified by the
manufacturer and approved for use by the architectural paver manufacturer, may be substituted for either bedding sand, joint sand or both when specified in the Plans and appro ved by the Engineer.
526-3 Construction Methods.
526-3.1 General:
526-3.1 1 Submittals: For Architectural Pavers – Roadway, furnish full size
samples to the Engineer for approval prior to beginning placement. For Architectural Pavers - Sidewalk, submit to the Engineer a certification that the architectural pavers meet the requirements of this Section. In addition, for all architectural pavers , submit a certified sieve analysis for gradation comparing results of the bedding sand and joint sand with the requirements of ASTM C33 or ASTM C144 as applicable.
