1.03 <br />J�V <br />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 />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 />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 />
