recommendations . During all stages of manufacture, shipment , storage , and construction, protect and handle blocks in a manner to prevent physical damage. Do not use any method of lifting or transporting blocks that create dents or holes in block surfaces or that cause losses of portions of block. If blocks are to be stockpile d at the project site before placement, designate a secure storage area that is located away from any heat source or construction activity that produces heat or flame. Personal tobacco smoking or flames of any kind are not allowed in the storage area. Store blocks off of the ground and out of standing water. Protect blocks from direct sunlight and UV rays . Do not place a cover directly over blocks that might allow the buildup of heat beneath the cover. Do not traverse blocks with vehicles or equipment, and foot traffic by persons must be kept to a minimum. If blocks are exposed to wind, secure with sandbags or other similar “soft” weights that do not dent or otherwise damage blocks. Protect blocks from contact with and exposure to vapors from organic solvents, including but not limited to acetone, benzene and mineral spirits , and petroleum based solvents, including but not limited to gasoline, kerosene, and diesel fuel.
Provide a scale with a rated capacity of no more than two and one half times the weight of the heaviest block delivered to the site and accurate to a tenth of a pound. Provide documentation that the scale has been calibrated after being set up at the site. Verify block density by selecting a random block from each truck load of blocks delivered to the project. If the random block is not within d ensity requirements, the entire truck load will be rejected. Individual blocks from a rejected truck load may be accepted if confirmed to be within density requirements. Record the following information: date and time of measurement, ASTM EPS designation as specified in Table A, dimensions and weight of the block, and the calculated density (i.e., block weight divided by block volume). Provide this information to the Representative upon request.
review and acceptance. Indicate on the shop drawings the proposed location and layout of all blocks ; location and thickness of bedding material , capping material, embankment material , and pavement section; and the location of the geot extile and geomembrane. The proposed layout must meet the following requirements:
• Place Type 1 blocks for the main body of the fill.
• Cap the top of the Type 1
