ROAD MAINTENANCE

PART l: GENERAL

1.01 WORK INCLUDED:

A. Description: Work consists of blading and shaping existing roads to restore proper drainage.

Work is described and scheduled on the Work Data Sheet.

1.02 DEFINITIONS

A. Reshaping the road surface requires cutting through the crust to remove potholes, washboard, and ruts. The material is redistributed across the roadway.

B. In case weather makes it questionable whether the work can be completed within the dates specified, the Contracting Officer may extend the Contract.

1.03 PROJECT CONDITIONS:

A. Public Safety and Signing: The Contractor shall exercise due caution and care when operating equipment to prevent undue conflict with public users of the road.

l. A reflective "Slow Moving" vehicle symbol shall be attached to the rear of all appropriate equipment.

2. Post warning signs on both ends of the section being worked on. Signs shall be moved as needed, so that a sign does not precede the machinery more than one mile. Signs shall be of the size, style, and color as required

3. . Berms, windrows, or other obstructions shall not be left in the roadway overnight or on weekends.

1.04 QUALITY ASSURANCE:

A. Failure Criteria: Not limited to the following:

1. Formation of pools of moisture on road surfaces. Site drainage shall be considered to be of prime importance.

2. Flow of moisture toward, or entrapment against culvert foundations.

3. Grading of material into pits, streams, rivers, or other waterways.

4. Road grader induced washboards on the travel surface.

5. Roadway crown created is not within specification as set forth in the provided specifications document.

PART 2: PROJECT/SITE CONDITIONS

2.01 TIMING

A. Maintenance/improvement shall begin in June after the roads have thawed and dried to an appropriate moisture level. The Nulhegan Basin Division Office will notify the Contractor 7 days in advance of the date they wish blading operations to begin. These conditions usually occur between June 1 and July 15, however, work may be performed outside of these windows if there are adequate moisture conditions. All work will be performed in a timely manner when appropriate moisture is present for satisfactory performance.

B. The maintenance/improvements shall be done when adequate moisture is present for satisfactory performance. The Government shall instruct the Contractor when conditions are either to dry or too wet for grading. However, as a rule of thumb the following may be used to determine moisture readiness: if a half ton pickup leaves ruts of greater than 2" then the roads are too wet and if one cannot dig down 2" and find moisture then conditions are likely too dry.

PART 3: EXECUTION

3.01 INSTALLATION

A. Contractor will furnish a road grader with operator that has a minimum of 135 horsepower, 12 foot blade, and a scarifier. Where potholes, washboards, or ruts are over 3" deep, scarify to a minimum depth of 3-4 inches below the road surface, process the material, and reshape the surface.

B. Road width: Road segments shall be maintained to uniform widths. This does not mean that every road will be of uniform width from start to end, but that each segment of road will be essentially uniform.

C. Grades: Grades shall be maintained to the present grade between points, or uniform slopes where elevations change. Abrupt changes in slopes shall be rounded.

D. Blading: Blading of road surfaces will be done to minimize the loss of aggregate material. High blading, which is merely filling depressions with loose material, will not be acceptable.

Berms or ridges shall not be left along the shoulders. During the blading operation, material shall not be graded into pits. All loose rock larger than 6 inches shall be removed from the roadbed. Road segments being bladed shall not be longer than 2 miles in length.

Berms/windrows created during blading operations shall be removed prior to the end of each day. Edges or berms created at approaches shall be feathered and smoothed.

E. A uniform crown of 2% in straight sections where crown has been established prior to contract is desired. Contractor shall work towards creating crown in other sections.

Super elevation on curve sections is desired, including smooth transitions to a straight section crown.

F. Excess and unsuitable material including rocks, boulders or clumps of vegetation that cannot be used on the road surface shall not be left as berms or ridges on the travel way or left where it can block flow in ditches or to culverts
