2. CS - Commercial Standard Issued by U.S. Department of Commerce.

3. EPA - Environmental Protection Agency.

4. FAR - Federal Acquisition Regulation System.

5. FED SPEC - Federal Specifications.

6. FSS - Federal Specifications and Standards.

7. MSHA - Mine Safety Health Administration.

8. MUTCD - Manual of Uniform Traffic Control Devices.

9. NBS - National Bureau of Standards.

10. OSHA - Occupational Safety and Health Act.

11. PS - Product Standard issued by the U.S. Department of Commerce.

12. UL - Underwriter’s Laboratories, Inc.

QUANTITY MEASUREMENT TERMS

1. Measurement under the contract shall be according to the United States standard measure.

2. The methods of measurement and computation will be those necessary to accurately determine the quantities of materials furnished and work performed.

3. All items that are measured by the linear foot will be measured parallel to its longitudinal centerline, unless otherwise shown on the drawings.

4. A station when used as a definition of term or measurement will be 100 linear feet.

5. Miles will, in the absence of known distances from existing plans or surveys, be determined by the

Government using a calibrated survey odometer or equal substitute operated on the traveled way at or parallel to road centerline.

6. Single lane mile measurement will mean the product of the road length in miles times the equivalent number of continuous traveled way lanes on the road. On two (2) lane roads, the lane miles will be twice the length of the road segment maintained. On one- (1) lane roads, the added length of turnouts will be determined by using a factor that includes the cumulative length of the turnouts. Unless a different factor is established in Special Project Specifications or listed for each affected one (1) lane road in the Road Listing, forty percent (40%) of the road will be considered as having turnouts; this yields a factor of one point four (1.4) times the length in miles of the road segment maintained. This adjustment applies only to work performed under Section 811.

7. The term “ton” will mean the short ton consisting of 2,000 pounds avoirdupois. Trucks used to haul material measured by truck weight shall be weighed empty at least once daily, and each truck shall bear a plainly legible identification mark. Weigh tickets furnished by the Contractor from certified scales will be used to determine weight measurements.

8. Materials measured by the cubic yard in the hauling vehicle shall be measured therein at the point of delivery. Vehicles may be of any size or type, provided that the box is of such shape that the actual volume may be readily and accurately determined.

9. Measurement by the acre will use the length and width treated. Measurement of width will approximate significant slope breaks, but will not include minor deviations along the slopes. The measured slope distance for width will be multiplied by the length treated and converted to a standard 43560 square foot acreage value of the surface area treated.

10. Volume of bituminous products will be measured at 60 degrees F, using ASTM D-1250 for asphalts except the quantity of emulsified asphalt will be determined by measuring the emulsified asphalt at a temperature of 60 degrees F, or by converting the gallonage measured at another temperature to gallonage at 60 degrees F by means of the following formula:

Gals. at 60 degrees F = Gallons at A degrees F

1+0.00025(A degrees F - 60 degrees F)

In which A degrees F is the temperature of the material at the time the gallonage is measured.

11. The term “lump sum” when used in the SCHEDULE OF ITEMS will mean the complete unit as required by or described in the contract.

Upon final blading, no disturbed rock shall protrude more than two (2) inches above the adjacent surface unless otherwise provided in the contract. Material not meeting this dimension shall be removed and placed outside the roadbed so as not to obstruct drainage ways or structures. This material may be scattered off the roadbed if there is free drainage.

c. Routine Blading

1. Upon completion of blading, the surfaces shall conform to the dimensions shown in the DRAWINGS.

2. Roadbed width in excess of the dimensions shown shall be shaped only as needed to provide drainage away from the traveled way. Established grasses and other vegetation shall not be removed from the excess width except as incidental to providing drainage or unless otherwise provided in the contract.

d. Compaction

Unless Compaction Method A is included in the SCHEDULE OF ITEMS and ROAD MAINTENENCE REQUIREMENT SUMMARY, all traveled ways requiring compaction shall be compacted by Method B.

Compaction shall commence immediately following blading. Contractor shall apply water prior to and during blading when sufficient moisture is not present to obtain the required compaction and prevent segregation

f. Undercutting - Roadway back slope shall not be undercut.

g. Intersections

1. At intersections, the roadbeds of side roads which are not closed or restricted from vehicular use shall be bladed to assure smooth transitions.

2. Field evidence of closure or restrictions shall be considered to be signing, cross ditching in the road surface (traveled way), earth berms or other devices placed to discourage or eliminate use by passenger cars, also roads listed for work under Sections 835 or 838 shall be considered restricted.

3. Side roads listed for work under this Section shall be considered as not restricted.

Rates of application shall be varied as needed but shall be low enough to avoid forming rivulets.

Frequency of application shall be sufficient to accomplish the abatement without saturating and softening the traveled way. Compacted or glazed road surface or wheel tracks may be loosened as needed for water penetration.

b. Prior to initial application, when needed the road will be ordered bladed and shaped under Section 811, Blading.

c. Required subsequent applications may be applied to the existing road surface without blading unless it is ordered.
