DIVISION 100 - ROAD SURFACE ACTIVITIES

ACTIVITY CODE 109 – GRADING (MOTOR GRADER)

Maintenance Requirements

Blading operations shall be conducted as required and shall include removal of ruts, potholes, corrugations and bumps with a scarifier. All suitable dislodged aggregate shall be smoothly redistributed over the entire travelway to provide proper cross slope or crown (2% to 4% slope). Blading area shall be from outside edge of shoulder to outside edge of shoulder on existing road surface and shall include turnouts, curve widenings and turnarounds.

Suitable moisture content of surface aggregate during blading shall be from five to fifteen percent by weight. The Contractor is responsible to insure that blading operations are performed within the specified moisture content limits. All suitable aggregate which has been worked onto road shoulder by traffic or maintenance activities shall be reclaimed onto the travelway. A definite, continuous and smooth line between aggregate surface and road shoulder shall be obtained. Grass or leaf litter deposited within the travelled way shall be smoothly spread within the travelway or along the shoulder after movement sufficient to sift out surface aggregate. In some instances, hauling of excess grass or leaf litter will be required to remove this material from the road surface simultaneous to blading operations. Disposal sites shall be locations approved by the COR. The maximum haul distance required is 1 mile, undercutting of the road surface at the shoulder line and leaving material berms is unacceptable. No material shall be allowed to remain on shoulders or in ditch lines as a result of the contractor's operation.

Minimum blading work shall be five passes with the grader on any road section. Passes will not exceed 1 mile intervals along any length of road and at any one time without the approval of the COR. Maximum blading speed shall be such that surface aggregate rolls and mixes from the angled blade of the motor grader and such that bouncing of the motor grader and the creation of a corrugated road surface from blading operations is prevented. Loose rocks protruding 4 inches or more above the graded surface shall be removed from the travelway. It is permissible to waste these rocks on Forest Service land, beyond the roadside mowing limits and away from drainage ditches as approved by the COR. Travelways (aggregate surface) shall be maintained over the full existing width. Dips and swales within the travelway designed to control surface drainage shall be maintained. Mailbox turnouts along roads shall also be maintained as part of the road. Blading and handwork may be required to maintain mailbox turnouts. Mailboxes shall be protected during maintenance activities.

The Contractor will be held responsible for any damage caused by his blading operations to utilities, the road or existing associated road structures such as culverts, header walls or bridges.
