2. MAINTENANCE REQUIREMENTS

h. Timing

i. Surface blading shall be performed during the contract period as ordered by the Government.

j. General

k. 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 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. In general, the road shall have a cross slope with ranging percentages typically 3-6%, although that may be higher based on road conditions, that shall provide for proper drainage. 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.

l. 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.

m. 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.

n. 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.

1) 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.

o. Routine Blading

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