Material Too Granular to Test Clause Samples

Material Too Granular to Test a. Construct embankments with material too granular to test by Idaho Method T-74 in horizontal layers no thicker than 18 inches unless otherwise permitted. Distribute large rocks evenly and fill the voids between them with smaller rock and/or earth. Also, provide adequate water to facilitate compaction. b. Place and uniformly compact each layer more than 18 inches below subgrade with a minimum of 3 full coverages for each 6 inches of lift thickness or fraction thereof with rollers with the following minimum requirements. c. Vibratory rollers having a rated dynamic force of 30,000 pounds per impact and at least 1000 vibrations/minute. d. Grid rollers having a static weight of at least 20,000 pounds and 4000 pounds/foot of drum width. e. Rolling requirements may be reduced 1 coverage per 6 inches, or fraction thereof, for each increase of 5,000 pounds per impact for vibratory rollers or 1,000 pounds/foot of drum width for grid rollers. f. One complete coverage for each 6 inches of lift thickness is the minimum allowed. g. Rock material placed within 18 inches of subgrade and rock backfill of overexcavated areas in rock cuts shall be constructed in layers not exceeding 9 inches thick, unless directed otherwise. Each layer shall be uniformly compacted with a minimum of 12 full coverages of a vibratory roller meeting the minimum requirements previously stated. Vibratory rolling may be reduced one full coverage for each increase of 5000 pounds per impact above the minimum. In no case will less than 6 full coverages per 9-inch lift, or fraction thereof, be allowed. h. Limit the speed of grid rollers to no more than 4 mph and the speed of vibratory rollers to no more than 1.5 mph. i. Include the cost for this work under other earthwork items, since all work described in this Subsection is considered incidental.
