ROAD MAINTENANCE

MT-02233-1

SECTION MT-17301

1.01 WORK INCLUDED:

B. Related Sections:

General Information and Requirements SECTION MT-01009 Mobilization SECTION MT-01505 Crushed Aggregate Base Course SECTION MT-02233 Watering SECTION MT-02201

1.02 DEFINITIONS

A. Smoothing is dragging the grader blade across the road to level the surface and drag excess material away. Smoothing does not cut the surface crust.

B. Reshaping the road surface requires cutting through the crust to remove potholes, washboards, and ruts. The material is mixed to provide a blend of different size aggregates, and distributed across the roadway.

C. Scarifying is breaking up the old surface crust, using the ripper teeth of the grader.

D. Processing is mixing the aggregate material to incorporate or remove moisture and blend the various sizes of material.

E. Spreading is evenly distributing the new crushed aggregate base course across the roadway at a depth in accordance with the typical section and drawings.

F. Compacting the new crushed aggregate base course involves using equipment and machinery to compress the aggregate in the roadway until it reaches a density value a minimum of 95% its theoretical maximum density at a moisture content within 3% of optimum.

1.03 PROJECT CONDITIONS:

A. Moisture Conditions: Whenever the Contractor or the Contracting Officer determines that the moisture conditions prevent obtaining a satisfactory job, work will stop and will not be resumed until moisture conditions are favorable, or until the Contracting Officer requests watering of the road to achieve appropriate moisture conditions.

Measurement and payment for Watering directed by the Contracting

MT-02233-2

Officer shall be per SECTION MT-02201. This requirement may be waived when the Contracting Officer requests grading be done by a specified date.

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

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

2. Post warning signs on both ends of the section of road 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 required in the current edition of the "Manual on Uniform Traffic Control Devices for Streets and Highways - MUTCD".

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. Compaction of new road base course. The new road base course surface shall be compacted to 95% of the theoretical laboratory maximum density (as determined by ASTM D698) while the material is within 3% of the optimum moisture content. Density testing may be performed by BLM personnel at the Contracting Officer’s discretion using a Nuclear Densometer.

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

3. Settlement of fill. All material placed as fill shall be compacted to a minimum of 95% the theoretical laboratory maximum density (as determined by ASTM D698) within 3% of the laboratory optimum moisture content. Density testing may be performed by BLM personnel at the Contracting Officer’s discretion using a Nuclear Densometer.

4. Flow of moisture toward, or entrapment against, cattleguard and culvert foundations.

5. Grading of material into cattleguard grids or pits, road ditches, streams, rivers, wetlands, springs, or other waterways.

(There are no applicable requirements.)

MT-02233-3

3.01 INSTALLATION

A. Ditches: Ditch cleaning is not required in this contract. The contractor shall avoid driving machinery and vehicles in road ditches. Any ruts created in the ditches, loss of vegetation in the ditches, or damage to the ditch slopes caused by the contractor will be repaired and reseeded at no cost to the Government.

B. Culverts: Culvert cleaning is not required in this contract. In the event culverts, end sections, or both are damaged due to actions of the Contractor, repairs or replacement shall be made at no cost to the Government.

C. Slough Material: Slough material may be bladed across the road, provided it is not deposited in potholes, washes, or ruts in the roadbed. The material shall not be side-cast into streams, streambeds, creeks, wetlands, or springs.

D. Scarification: Where potholes, washboards, or ruts are over 1” deep, scarify to a minimum depth of 3-4 inches below the road surface, process the material, and reshape the surface.

E. Road width: Road widths shall be those from the designated typical sections as shown on the project drawings.

F. Grades: Grades shall be maintained according to the designated typical sections as shown on the project drawings, or maintained as uniform slopes where elevations change. Abrupt changes in slopes shall be rounded.

G. 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, except where required for safety. During the blading operation, material shall not be graded into cattleguard pits. All loose rock larger than 3 inches shall be removed from the roadbed.

1. Double lane roads will be crowned at 3%, except on corners. Corners will be superelevated per the direction of the COR. Make smooth transitions between the crown and superelevated cross sections.

2. Sections of roads constructed with roadside ditches shall be bladed and reshaped to drain the water from the roadbed. The cross section shall match the designated typical sections as shown on the project drawings and follow Part 3.01.G.1.

H. Spread the new crushed aggregate base course evenly across the road to widths and depths in accordance with the typical sections detailed on

MT-02233-4

the construction drawings, or at the discretion of the Contracting Officer.

I. Sufficiently compact the new crushed aggregate base course using a smooth drum roller or equivalent. Compact the new crushed aggregate base course to a minimum of 95% the theoretical laboratory maximum density (as determined by ASTM D698) within 3% of the laboratory optimum moisture content.

J. New Road Base Course Material: All road base course material transported to the site will be used to surface the road. Depths may vary depending on the portion of the road and its need, as directed by the Contracting Officer. If the Contracting Officer feels that the road is sufficiently surfaced and meets the minimum requirements of the typical sections of the drawings, a small amount of material may be added to the existing gravel pile near the Acton Recreation Area parking lot for future maintenance projects, as directed by the Contracting Officer.

K. Disposal of Unsuitable Material: Unsuitable material, including rock and boulders that cannot be used in road embankment, shall be disposed of away from the road, pads, or parking lots. Unsuitable material shall not be left as berms or ridges and shall not be left where it can block flow to ditches or culverts. The material shall not be side-cast in road ditches, cattleguard grids or pits, streams, streambeds, creeks, wetlands, or springs. Coordinate disposal efforts with the Contracting Officer for approval.
