Weathered rock, dense consolidated deposits, or conglomerate materials which are not included <br /> in the definition of "rock" but which usually require the use of heavy excavation equipment, <br /> ripper teeth, or jack hammers for removal. <br /> B . Rock <br /> Solid homogeneous interlocking crystalline material with firmly cemented, laminated, or <br /> foliated masses or conglomerate deposits, neither of which can be removed without <br /> systematic drilling and blasting, drilling and the use of expansion jacks or feather wedges, <br /> or the use of backhoe-mounted pneumatic hole punchers or rock breakers; also large <br /> boulders, buried masonry, or concrete other than pavement exceeding 1 /2 cubic yard in <br /> volume Removal of hard material will not be considered rock excavation because of <br /> intermittent drilling and blasting that is performed merely to increase production. <br /> C. Cohesive Materials <br /> Materials ASTM D 2487 classified as GC , SC, ML, CL, MH, and CH. Materials classified <br /> as GM and SM will be identified as cohesive only when the fines have a plasticity index <br /> greater than zero . <br /> D. Cohesionless Materials <br /> Materials ASTM D 2487 classified as GW, GP, SW, and SP. Materials classified as GM <br /> and SM will be identified as cohesionless only when the fines have a plasticity index of <br /> zero. <br /> 1 .03 SUBMITTALS <br /> A. The following Test Reports are to be obtained and paid for by Contractor <br /> 1 . Fill and backfill optimum density test where specified <br /> 2 . Select material optimum density and gradation tests <br /> 3 . Compaction density tests where specified <br /> 4. In-place density tests where specified <br /> 1 . 04 DELIVERY, STORAGE AND HANDLING OF MATERIALS <br /> Perform in a manner to prevent contamination or segregation of materials. <br /> PART 2 - PRODUCTS <br /> 2 .01 SOIL MATERIALS <br /> Free of debris, roots, wood, scrap material, vegetation, refuse, soft unsound particles, and deleterious <br /> or objectionable materials. Unless specified otherwise, the maximum particle diameter shall be one- <br /> half the lift thickness at the intended location. <br /> A. Common Fill <br /> Common shall consist of sandy-loam, sand, gravel, soft shale, or crushed stone. The <br /> Engineer shall be the sole judge of what constitutes suitable and unsuitable material for <br /> backfill from "on-site excavations." <br /> 02302 — Excavation and Fill <br /> 02302 - 2 <br />
