SHOULDER RECONSTRUCTION PER SHOULDER MILE: (1-18-00) (Rev. 12-23-25) 560, 1019 SP1 R07R Description Clip high shoulders and reconstruct the earth shoulder in accordance with Standard Drawing No. 560.01 and 560.02 of the Roadway Standard Drawings, except that the shoulder width will be established by the typical sections or to the existing shoulder point, whichever is nearer, so that the desired typical is achieved. Perform shoulder reconstruction immediately following resurfacing operations. When borrow excavation material is used for shoulder reconstruction, perform seeding and mulching upon its completion. Materials Use aggregate shoulder borrow (ASB) for all shoulder reconstruction unless the area is designated as a residential lawn, in which case borrow excavation material shall be used. The requirement to use borrow excavation material in residential lawn areas may be specified in the contract or directed by the Engineer. ASB shall meet the following gradation: Sieve Percent Passing 1 1/2" 100 1/2" 55 - 95 #4 35 - 74 Furnish all borrow excavation material necessary for shoulder reconstruction in accordance with Section 1019 of the Standard Specifications. All borrow excavation material furnished is subject to testing and may be accepted or rejected by the Engineer. Construction Methods Obtain all material from within the project limits or an approved source. Prior to placing aggregate shoulder borrow, scarify the existing shoulder to provide a proper bond and compact the shoulder as directed by the Engineer. Dispose of excess material generated by shoulder reconstruction in an approved disposal site Shoulder Reconstruction will be measured and paid in shoulder miles based on the full length of the map as designated in the contract. If only one side of a map requires reconstruction, the quantity will be equal to the map length. If both sides of a map require reconstruction, the quantity will be equal to twice the map length. If reconstruction is performed on only a portion of a map side, the full map length for that side will still be paid. The quantity will be determined from the map length shown in the contract and will not be adjusted based on field verification of the actual length of shoulder reconstructed. Shoulder Reconstruction will only be paid for maps, or sides of maps, where the work is performed. Payment will be made at the contract unit price per shoulder mile and will constitute full compensation for disposal of excess material in an approved disposal site and for all labor, tools, equipment, and incidentals necessary to complete the work in accordance with the contract. Aggregate Shoulder Borrow will be measured and paid at the contract unit price per ton incorporated into the completed work and accepted by the Engineer. The number of tons is determined by weighing the material in trucks in accordance with Article 106-7. No deductions will be made for any moisture contained in the aggregate at the time of weighing. Borrow Excavation will be measured and paid in accordance with Section 230 of the Standard Specifications for earth material furnished by the Contractor. The requirements of Article 104-5 of the Standard Specifications pertaining to revised contract prices for overrunning minor items will not apply to the item of Borrow Excavation. Incidental Stone Base will be measured and paid as provided in Article 545-6 of the Standard Specifications. Where Aggregate Shoulder Borrow is used, Incidental Stone Base will not be required.
