Satisfactory material for use as fill for public streets include material classified in ASTM D -2487 as GIN, GP, GM, GC, SW, SP, SM, SC, ML and CL groups. The moisture content shall be controlled within plus or minus 2 percentage points of optimum to facilitate compaction. Generally, unsatisfactory materials include materials classified in ASTM D -2487 as PT, CH, MH, OL, OH, and any soil soil too wet to facilitate compaction. CH and MH soils may be used subject to approval of the VDOT Engineer. Soils shall have a minimum dry density of 92 lb. /cu.ft. per ASTM D -698 and shall have a liquid limit less than 17. 10. Compaction of fill material under building slabs shall be based upon recommendations of soils engineer after completion of standard Proctor test and shall meet bearing requirements of architect of buildings.

Materials used to construct embankments for any purpose, back -fill around drainage structures or in utility trenches or any other depression requiring fill or back -fill shall be compacted to 95% of maximum density as determined by the standard Proctor test as set out in ASTM standard D -698. The contractor shall, prior to any operations involving filling or back - filling submit the results of the Proctor tests together with a certification that the soil tested is representative of the materials to be used on the project. Tests shall be conducted by a certified materials testing laboratory and the certifications made by a licensed professional engineer. 12. All excavations, including trenches, shall be kept dry to protect their integrity. 13. Any discrepancies found between the drawings and specifications and site conditions or any inconsistencies or ambiguities in drawings or specifications shall be immediately reported to the engineer in writing, who shall promptly address such inconsistencies or ambiguities.

All materials and construction methods shall conform to current specifications and standards of VDOT unless otherwise noted. 3. Erosion and siltation control measures shall be provided in accordance with the approved erosion control plan and shall be installed Prior to any clearing, grading or other construction. 4. All slopes and disturbed areas are to be fertilized, seeded and mulched. 5. Themaximum ve allowable slope is 2:1 (horizontol:rtical). Where reasonably obtainable, lesser slopes of 3:1 or better are to be achieved. 6.
