811 SURFACE MAINTENANCE
811.01 Service Required Smooth and shape native or aggregate surfaced roads including traveled way, shoulders, turnouts, and intersections. Reshape or recondition ditches, water bars, and drain dips.
811.02 Performance Standards A. Maintenance Level 4 and 5 Roads
A road surface is maintained to standard when the travel way is free of washboards, potholes, or other irregularities. The surface is smooth, compact, crowned or sloped to drain, without segregation of the surfacing materials. Suitable materials have been recovered and incorporated. Unsuitable materials have been removed. Ditches and road surface drainage structures function efficiently. Unpaved shoulders are shaped to provide a smooth transition from the paved surface and drain efficiently.
B. Maintenance Level 3 Roads A road surface is maintained to standard when the surface is compact, crowned, or sloped to drain, without segregation of the surfacing materials. The road surface has no ruts or rills, suitable materials have been recovered and incorporated. Unsuitable materials have been removed. Ditches and road surface drainage structures function efficiently.
C. Maintenance Level 2 Roads
A road surface is maintained to standard when the surface is shaped to drain, and where ditches and road surface drainage structures function efficiently. The road surface has no continuous ruts or rills, and no large concentrations of unsuitable materials remain.
D. All Roads
When ordered by the Contracting Officer to work in a weed infested area the contractor will be required to prevent spreading the infestation into un-infested areas by cleaning vehicles and equipment. The contractor will use wash stations approved by the Contracting Officer.
811.03 Location of Work
As specified on roads listed on the road listing, shown on the plans, marked on the ground, or as ordered by the Contracting Officer. Locations of weed infested areas are marked on the ground. Do not operate in the weed infested areas unless ordered to do so by the Contracting Officer.
811.04 Measurement
Measurement under this Section will be made by the total number of units for each item listed in the SCHEDULE OF ITEMS completed and accepted.
A. Single Lane Roads: Surface maintenance will be measured along the centerline of the roadway. Turnouts are incidental. Measurement will be to the nearest one-tenth (0.1) mile.
B. Double Lane Roads: Surface maintenance will be measured along the centerline of the roadway. Measurement will be to the nearest one-tenth (0.1) mile.
C. Road Mile: Work activity will be measured along the centerline of the road regardless of the number of lanes.
811.05 Payment
The accepted quantities will be paid at the contract price per unit of measurement for the Section 811 pay items listed in the schedule of items. Payment will be full compensation for the work prescribed in this Section.
