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.

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.
