PART 2: PROJECT/SITE CONDITIONS
2.01 TIMING
A. Maintenance/improvement shall begin this spring after the roads have thawed and dried to an appropriate moisture level. The Glasgow Field Office will notify the Contractor 7 days in advance of the date they wish blading operations to begin. These conditions usually occur between April 15 and July 31, 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
3.0 l INSTALLATION
A. Contractor will furnish a road grader with operator that has a minimum of 135 horsepower, 12 foot long 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 gravel 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 cattle guard 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%-3% 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.
