Attachment 002 Statement of Work NFSR 272 Road and Ditch Repair 41 of 53

Quality Standard Blading operations shall be conducted over the entire riding surface in order to remove, by cutting out, all ruts, potholes, corrugations and berms. All suitable dislodged aggregate shall be smoothly redistributed over the entire riding surface to produce the proper cross slope or crown Aggregate surfacing which has been worked onto road shoulders by traffic or maintenance activities shall be reclaimed and smoothly redistributed over the entire riding surface. No undercutting of road surface or material berms will be allowed.

Assure proper surface drainage after all operations.

Usual amounts of grass, leaf litter or pine straw shall be smoothly spread within the riding surface after movement sufficient to sift out surface aggregate.

Blading operations shall be conducted as required to remove surface material and accumulated debris from concrete bridge decks.

Care will be taken to avoid blading any surface material into cattle guards.

Loose rocks protruding three inches or more above the graded surface shall be removed. It is permissible to waste these rocks off the riding surface away from drainage ditches.

Ditch Maintenance Requirements

A. Maintain ditches by removing rock, soil, wood, and other materials.

Maintained ditches shall function to meet the intent of the original design.

B. Undercutting backslopes during removal operations is not permitted.

C. Suitable material up to 4 inches in greatest dimension removed from the ditches may be blended into existing native road surface and shoulder or placed in designated berm.

D. Do not blend material from ditch cleaning operations into aggregate surfaced roads. Do not blade material across aggregate or bituminous surfaced roads, unless approved in writing.
