QUANTITY MEASUREMENT TERMS

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

The methods of measurement and computation will be those necessary to accurately determine the quantities of materials furnished and work performed. Measurement will be made of each item or unit of work, as shown in the Schedule of Items, completed and accepted in accordance with the contract provisions, specifications, and drawing.

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

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

3. 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. 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.

4. 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.

5. 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.

6. 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 43,560 square foot acreage value of the surface area treated.

7. Volume of bituminous products will be measured at 60° 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° F, or by converting the gallonage measured at another temperature to gallonage at 60° F by means of the following formula:

Gallons. at 60° F = Gallons at A° F

1+0.00025 (A° F − 60° F)

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

8. The term "lump sum" when used in the Schedule of Items will mean the complete unit as required by or described in the contract.

3) Existing native, rock or aggregate surfaced drainage dips shall be shaped incidental to blading to divert surface runoff to existing outlet devices, ditches and discharge locations.

4) The Contractor shall establish a blading pattern which provides a uniform driving surface, retains the surfacing on the roadbed and provides a thorough mixing of the materials within the completed surface width. 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.

5) Watering will not be required for smooth blading. Smooth blading shall be accomplished without distorting the existing cross-slope or crown of the traveled way. Loose surfacing materials shall be moved and stored on the high side of super-elevated curves and sections with uniform inslope or outslope. In crowned sections, the material shall be stored on either or both sides as elected. Stored materials shall be windrowed and shall be placed to provide not less than eleven (11) feet of smoothed traveled way on one- lane segments or twenty (20) feet of smoothed traveled way on two-lane or sections with turnouts. Windrows which may collect water on the road shall have holes cut through for drainage at least every 500 feet.

c. Routine Blading

1) Upon completion of blading, the surfaces shall conform to the dimensions shown in the Special Project Specifications 811-3.

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

Roads requiring compaction will be included in the Road Listing. Unless otherwise specified, all traveled ways requiring compaction shall be compacted by breaking track while operating equipment on the traveled way.

e. Intrusions

Where the minimum width shown in the Special Project Specifications is not available, the Contractor will construct berms where ordered and marked on the ground. Material to provide berms will come from sources designated in the Special Project

Specifications.

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.

h. Cleaning of Structures

Materials resulting from work under this Section shall not be allowed to remain on or in structures, such as bridges, culverts, cattleguards, or drainage dips.

i. Berms

Existing berms shall be maintained to the condition of adjacent segments when ordered by the Government.

3. MEASUREMENT

a. Measurement under this Section will be made by the total number of units for each item listed in the Schedule of Items completed and accepted.

b. Measurement for blading will be single-lane mile measured along the centerline of the roadway (see quantity measurement terms). Two-lane roads will be measured as two

(2) single-lane miles. Measurement will be measured to the nearest one-tenth (0.1) mile.

c. Each intersection bladed under 2.g. will be equivalent to one-tenth (0.1) single-lane mile; however, when the intersecting side road is scheduled for subsequent blading under this Section, no measurement will be made.

d. Berm maintained or established will be measured by linear foot.

e. No measurement will be made under this Section for compaction method specified in

2.d. For roads needing compaction with special compaction equipment (ie. pneumatic or steel roller), use pay items in Section 807 for additional compaction efforts.
