FAR - Federal Acquisition Regulation System.

5.

FED SPEC - Federal Specifications.

6.

FSS - Federal Specifications and Standards.

7.

MSHA - Mine Safety Health Administration.

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.

811 BLADING (7/2009)

1.

DESCRIPTION

This work consists of surface blading native or aggregate roadbed where shown in the Haul Route and Dust Abatement Plan or Drawings to a condition to facilitate traffic and provide proper drainage. Blading includes shaping the crown or outsloping of traveled way, road side ditches, swales, shoulders, berms, and drainage dips in accordance with this specification. Work shall also include the maintenance of culverts, catch basins, and inlet basins.

2.

MAINTENANCE REQUIREMENTS

a.

Timing- Routine surface blading shall be performed during the contract period as ordered by the Government. Contractor shall commence surface blading within two (2) contract days after receipt of written order unless otherwise stated in the order.

b.

General

1.

The existing traveled way and shoulders, including turnouts unless otherwise ordered, shall be bladed and shaped to produce a surface which is uniform, consistent to grade, and crowned or cross-sloped as indicated by the character of the existing surface unless otherwise shown in the Road Listing, Schedule of Items and as Shown in the Drawings, to at least one half inch (1/2”) per foot of width, but not more than three quarter inch (3/4”) per foot of width. Surfacing materials shall be thoroughly loosened to no less than 2 inch depth or the depth of potholes or corrugations. Scarification to facilitate cutting to the full depth of potholes or corrugations may be elected by the Contractor but will be considered incidental to blading. Scarification shall not go deep enough to cause contamination of the surfacing. See Drawings for minimal blading width and additional requirements.

2.

When Section 891 is included in the Road Listing, the Contractor shall apply water during blading when sufficient moisture is not present to prevent segregation.

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 drainageways 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 Listing, all traveled ways requiring compaction shall be compacted by Method B. Compaction shall commence immediately following blading.

Compaction methods are:

Compaction Method A: By breaking track while operating equipment on the traveled way.

Compaction Method B: 8-10 ton pneumatic, steel or equivalent vibrating roller, operated to cover the full width five

(5) times.

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 Drawings.

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. See the following Sections for additional requirements:

831 – Ditch Maintenance

834 – Drainage Structures

835 – Roadway drainage Maintenance

877 – Drainage Dip Maintenance i.

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

3.

MEASUREMENT
