2.11 Crushed stone base course coarse gradation. Acceptable sand may be blended as necessary to obtain the proper gradation for the fine aggregate portion. 2.11.1 The substitution of crushed stone meeting the requirements of crushed stone base course fine gradation for all or part of this item will be permitted. Construction Requirements
crushed gravel or crushed stone, fine aggregate and binder or filler blended as necessary to produce an intimate mixture of the required gradation and stability. Requirements The aggregate shall consist of hard, durable particles of crushed stone or crushed gravel and a filler of natural sand, stone sand or other finely divided mineral matter.
Use only crushed stone in District 1. For select granular backfill material composed of crushed stone, submit a proposed project gradation with single-point gradations and tolerances for approval. For sand and sand-gravel combinations, a project gradation will be issued that will specify gradation tolerances after the proposed material is approved.
A. General Requirements. Fine aggregate is natural sand having hard, strong, durable particles meeting the gradation requirements in Table 701-2. Other approved inert material with similar characteristics or combinations of the above materials may be used, if the materials meet these specifications.

Aug 29, 2002 We normally recommend a No. 57 gradation crushed stone or gravel, and a thickness of 8 to 10 inches. If thicker layers are used, we recommend that each 12-inch thickness of stone backfill be densified by making 3 or 4 passes of a walk-behind vibratory sled or plate type compactor over the stone surface. Density testing is not performed.
