B) Stripping 1) VLF No work performed during the week. C) Subgrade Preparation 1) VLF Subgrade preparation was performed in the following areas: between stations 135+00 (+/-) and 137+50 (+/-), approximately 100 feet left of centerline to 20 feet right of centerline; between stations B 10+00 (+/-) and B 15+00 (+/-), approximately 0 to 125 feet left of centerline; between stations D0+00 (+/-) and D3+00 (+/-), approximately 30 feet left of centerline to 30 feet right of centerline; and between stations E4+00 (+/-) and E12+00 (+/-), approximately 100 feet left of centerline to 200 feet right of centerline. Various CAT dozers were used to rip the subgrade surface to a depth of 6" to 8". The subgrade was then moisture conditioned using a CAT 773 water tuck (when necessary) and compacted using a 10-ton vibratory smooth drum compactor. The entire surface of the subgrade was compacted with at least 4-passes. This area was inspected by an AMEC representative and accepted for structural fill placement.
