• Some compaction of fill slopes is desirable for slope <br />stability. Therefore, fill slope surfaces should be left <br />moderately rough with stones in place also. Besides providing <br />the benefits mentioned previously, this will help prevent <br />the movement or flow of unconsolidated material. <br />The roadway surface will require seeding and should <br />be left in a moderately roughened condition. Areas of the <br />road surface that consist of consolidated bedrock will require <br />topsoiling. Material suitable for this purpose can be obtained <br />from the pad area or from adjacent areas of moderately deep <br />to deep soil material. In most cases in areas of such extremes <br />in the natural occurrence of coarse fragments and rock <br />• outcroppings or stony materials in the soils, mechanical <br />treatments (or even drill seeding) are not Feasible. <br />Therefore, state-of-the-art revegetation techniques such <br />as broadcast seeding, mulching, and hydroseeding provide <br />the best available technology. <br /> <br /> <br />- 28 - <br />
