SECTION 02311

ROAD GRADING

PART 1 GENERAL

1.1 SUMMARY

A. Description of Work: Furnishing labor, equipment, supplies, and materials to grade and restore gravel and dirt roadways as specified on the plans, maps, exhibits, and as specified herein. Work shall be performed in accordance with the specifications and contract. The road sections include seven (7) areas, one of approximately 300 linear feet and others up to 100 linear feet each and are not contiguous. Installation of water bars. Weston Road is located in Campbell County, Wyoming.

B. Contractor shall ensure there is no additional disturbance to the road, shoulder, or adjacent landscape while moving equipment and motor grader between the road sections. The Contractor shall coordinate the grading of the road sections with the BLM in order to best determine when to perform work with precipitation and moisture conditions.

All road sections are primitive two-track, user created, and have minimal aggregate surfacing. The road sections shall be restored to a useable condition.

1.2 DEFINITIONS

A. Fill Material: Pit run material shall be mineral soil free from peat, frozen material, brush, trees, roots over 50 mm (2 inches) in diameter and rocks over 100 mm (3 inches) in greatest diameter.

1.3 QUALITY ASSURANCE

A. Failure Criteria: Not limited to the following:

1. Formation of pools of moisture where positive drainage is indicated on the drawings or as specified herein.

2. Settlement of fill.

1.4 PROJECT/SITE CONDITIONS

A. Environmental Conditions: Do not attempt to grade frozen or saturated material. The

Contractor shall coordinate the grading of the roads with the BLM in order time the work with precipitation and moisture content. Work will be postponed until conditions are favorable to minimize damage.

PART 2: PRODUCTS

2.1 EQUIPMENT AND MATERIALS

A. General: See definitions.

1. Road Grading Equipment: The Contractor shall provide a motor grader with a minimum 150 horsepower and twelve-foot blade. The cutting edges of the blade shall be in good condition, free from deformation due to excessive wear. All

WESTON HILLS GRADING 2021 02311 - 2 of 3 controls, including brakes, shall be in proper working condition to allow full control of the grading at all times.

PART 3: EXECUTION

3.1 PERFORAMANCE STANDARDS AND INSTALLATION

A. Grading

1. When not otherwise indicated, material shall be level, or uniform slopes between points where elevations are given, or between such points and existing finished grades. Abrupt change in slopes shall be rounded and blended. Finish grading shall match and blend into existing topography and promote positive drainage away from road surface with water bars. Site drainage shall be considered of prime importance.

2. Maximum graded side slope: 3H:1V B. Compaction Methods: Fill material shall be spread over the full area of the cross section of the fill to a maximum layer thickness of 6 inches (150 mm). Wheel tracking the fill may be used to obtain the required degree of compaction.

C. Water Bars: To be installed at various locations per Project inspector. See typical details.

D. Traffic Control:

1. The Contractor shall conform to MUTCD requirements for control of traffic in the work zone.

3.2 FIELD QUALITY CONTROL

A. The Owner reserves the right to conduct testing at any time.

B. Unless otherwise specified on the plans, provide positive drainage. The contractor will grade and compact such that no ponding greater than 4” deep nor larger than 1 sq. ft.

occurs.

PART 4: MEASUREMENT AND PAYMENT

4.1 METHOD OF MEASUREMENT

A. Measurement of topsoil stripping and replacement, grading, scarification, compaction, seeding shall be made per section of road grading completed in place as identified on the drawings, exhibits, figures, and as identified herein.

4.2 BASIS OF PAYMENT

A. Payment for each item shall be considered as full compensation for furnishing all labor, materials, tools, equipment, and other incidentals necessary to complete each component of the Work described in this Section.
