MACHINE GRADING SHOULDERS
212.01 Description.
This Section shall cover the work of reconstructing the shoulder of a roadway where the grading is of such character that the material can be moved, mixed, and shaped with a motor patrol of adequate power and weight {mass}. In general this work shall consist of clipping the shoulder, where directed, prior to resurfacing a nd blading the shoulder after the resurfacing has been completed. Any additional material needed to bring the shoulder to the desired profile will be classified and paid for under the appropriate section for the type material furnished. If seeding or other items are needed for erosion control, such items will be shown on the plans and paid for under the appropriate specification section. Unless otherwise noted by plan details, the completed work shall conform to the shoulder requirements for lines, grades, and typical section indicated by the plans or established by the Engineer.
212.02 Material.
Material used under this Section shall be of the quality and character noted on the plans or ordered by the Engineer, suitable for the purpose intended and consistent with the requirements for such material noted in other parts of this specification.
212.03 Construction Requirements.
a.General . Clipping, or blading, of grass and soil from the shoulder, as provided by the plans or directed, shall be complete d in advance of resurfacing operations. The removed material shall be windrowed a sufficient distance and in such a manner as not to pose a safety hazard to the motoring public. Where directed, the entire width of the shoulder shall be plowed, scarified or otherwise loosened. The shoulder then shall be re -formed by blading the material from the windrows, or by the addition of extra material as specified or directed, with the machine grader and compacting it to the satisfaction of the Engineer. Watering shal l be used, as necessary, to aid compaction. The machine grading shall continue until the shoulder is completed to conform to the lines, grades, and typical section shown on the plans or directed.
b.Equipment . The Contractor shall provide appropriately si zed equipment in sufficient numbers to perform the work within the guidelines noted herein and the time frame for the contract.
c.Additional Material . It will be considered practicable to move material up to 100 feet {30 m} longitudinally by means of the machine grader and all material moved within that limit will be paid for in the contract price for machine grading shoulders. When it is necessary to waste surplus material, such material shall be wasted on the front slope of the roadway in the vicinity o f the removal site, to the satisfaction of the Engineer. Material secured from sources outside the right of way will be classified under the applicable classification.
214.02 Material.
212.04 Method of Measurement.
Accepted machine grading of shoulders will be measured in hundred -foot {100 m} stations and fractions thereof to the nearest foot {1 m} of shoulder along the centerline of roadway, complete in place. Each shoulder graded will be measured separately. Borrow Excavation, Topsoil, or other material ordered used will be measured and paid for as provided by their appropriate sections unless otherwise specified.
212.05 Basis of Payment.
a.Unit Price Coverage . Machine grading of shoulders, measured as noted above, will be paid for at the contract unit price per station for machine grading, complete in place, which price shall be full compensation for the preparation, construction, and maintenance of the work involved, including blading, spreading, compacting, and dressing and for furnishing all equipment, tools, labor, a nd incidentals necessary to complete the work.
b.Payment will be made under Item No .: 212-A Machine Grading Shoulders - per station SECTION 214 STRUCTURE EXCAVATION AND BACKFILL FOR DRAINAGE AND MINOR STRUCTURES
214.01 Description.
a.General . The work under this Section shall consist of the removal and disposal of all excavated materials of any nature required for the construction of all box type culverts (including bridge type), pipe culverts (including pipe arches), storm drains, and other minor structures in accordance with these Specifications and to reasonably close conformity with the lines and grades shown on the plans or designated by the Engineer. This Section shall further include backf illing of structure foundations with suitable material in accordance with plan details or as directed.
b.Classification of Materials .
1.Excavation . All excavation for structures below natural ground or the designated subgrade, whichever is lower, or the elevation designated by the Engineer will be classified as Structure Excavation and shall include all materials encountered regardless of their nature, exclusive of water or other liquids which will not be classified as excavated material, necessary for t he proper construction of the structure. Excavation for ditches at the inlet and outlet ends of drainage structures and any other ditches indicated on the plans shall be constructed under "Roadway and Drainage Excavation" items.
2.Backfill .
a.Foundation Backfill. Special selected material ordered placed under a structure to provide a suitable foundation for the structure shall be classified as Foundation Backfill.
b.General Backfill. Material used for ordinary backf ill shall include special material for areas immediately adjacent to weepholes and a drainage belt for large masonry structures.
214.02 Material.
a.Foundation Backfill . Foundation Backfill is a special selected material suitable (approved free -draining c ommercial or local material) for use as foundation for the structure.
