The work covered by this section consists of the construction of roadway shoulders with approved earth material. When the contract provides for placing pavement on a previously graded roadway, the work of shoulder construction shall also include the reshaping and finishing of slopes adjacent to the shoulders and roadway ditches.
The material used in the construction of earth shoulders shall be material approved by the Engineer which has been obtained from unclassified excavation, fine grading operations, or from borrow sources as provided in Section 230.
The shoulders shall be constructed in proper sequence with the type of base and pavement being constructed. The work shall be performed in such a manner as to provide proper drainage at all times. The shoulder material shall be shaped and rolled during placement in such a manner as will provide for satisfactory bonding of layers and compacted to a degree satisfactory to the Engineer.
Prior to placing any earth material on existing graded shoulders, the Contractor shall remove all existing vegetation and scarify the existing shoulders as to ensure a proper bond.
The final shaping of the shoulders, adjacent slopes, and ditches shall be in accordance with the typical section shown on the plans or as directed by the Engineer.
The Contractor shall provide adequate equipment to perform the work. The Contractor shall exercise care not to damage base, surface, pavement, or drainage features during the construction of the shoulders. Should damage occur because of the Contractor's operations, the damaged portions shall be repaired or removed and replaced by the Contractor as directed by the Engineer at no cost to the Department.
(A) General:
Shoulder borrow will be measured in its original position or in the haul truck, as directed by the Engineer.
No measurement will be made of material transported directly from unclassified excavation or fine grading and deposited directly in the place on the shoulder.
(B) Measured in Original Position:
The quantity of shoulder borrow to be paid for will be the actual number of cubic yards of approved material, measured in its original position in the borrow source or stockpile by cross sectioning and computed by the average end area method, which has been incorporated into the completed and accepted work. No measurement will be made of any overburden or unsuitable material removed from the borrow source, nor of any material excavated prior to cross sections being taken.
(C) Truck Measurement:
The quantity of shoulder borrow to be paid for will be the actual number of cubic yards of approved material, measured in trucks, which has been incorporated into the completed and accepted work. Each truck will be measured by the Engineer and shall bear a legible identification mark indicating its capacity. Each truck shall be loaded to at least its measured capacity at the time it arrives at the point of delivery. The recorded capacity will be adjusted by making a 25 percent deduction to allow for shrinkage, and the adjusted capacity will be the quantity to be paid for.
The quantity of shoulder borrow, measured as provided in Article 5604, will be paid for at the contract unit price per cubic yard for "Shoulder Borrow", except as otherwise provided below.
When shoulder material is obtained as a result of fine grading operations, trenching out existing subgrade, and/or shaping slopes and ditches, no direct payment will be made for the work of shoulder construction as such work will be considered incidental to the work of constructing the base or pavement.
No payment will be made for the removal and disposal of any surplus material remaining in the stockpile after the shoulders have been completed.
Where the borrow source has been furnished by the Department, payment for clearing and grubbing the source will be made as provided in Article 2007 and payment for draining the source will be made as provided in Article 2405. Where the source has been furnished by the Contractor, no separate payment will be made for clearing and grubbing or draining the source as such work will be considered as incidental to the work covered by this section.
Payment for seeding and mulching all borrow sources will be made at the contract unit prices for the items established in the contract as payment for the work of seeding and mulching.
The above prices and payments will be full compensation for all work covered by this section including but not limited to furnishing the source of the borrow; building; maintaining, and obliterating haul roads; clearing and grubbing the borrow source; removal, hauling, and disposition of overburden and other unsuitable material; excavation; hauling; formation of roadway shoulders; restoration of the source and haul roads to an acceptable kcondition; disposal of surplus stockpiled material; and seeding and mulching.
Payment will be made under:
