211.01 Description This work shall consist of removing winter sand build-up and
other earth material from existing inslopes and ditches. New d itch areas consist of removing all material encountered including backslopes as needed.
211.02 Inslope Excavation From the edge of shoulder to the su bgrade break, the
inslope will be graded to the original template, or as directed by the typicals or construction notes. From the subgrade break to a location on the slope that does not create a hinge point, 2-40 the inslope shall be machine graded and finished to a smooth co ndition so that the flow of water is unimpeded.
211.03 Inslope Excavation - Guardrail Winter sand and other ea rth materials shall be
removed from all paved areas. From the edge of shoulder to the subgrade break, the inslope will be graded to the original template, or as directed by the typicals or construction notes. From the subgrade break to a lo cation on the slope that does no t create a hinge point, the inslope shall be machine graded and finished to a smooth condit ion so that the flow of water is unimpeded.
211.04 Inslope Rehabilitation Material shall be excavated from or placed on
inslopes. All inslopes shall be built, from the edge of should er to the toe of slope, to provide a 3 horizontal to 1 vertical minimum slope (1¾ horizontal to 1 vertical in guardrail sections), or as directed by the typicals or construction notes. Added ma terial shall be capable of attaining a growth of grass and shall be approved by the Reside nt
211.05 Ditch Excavation Ditches and adjacent slopes will be g raded to the original
template from the edge of shoulder to the top of the backslope, or as directed by the typicals or construction notes.
211.06 New Ditch Excavation Ditches and adjacent slopes will be graded from the
edge of shoulder to the top of t he backslope as directed by the typicals or construction notes.
211.07 Method of Measurement The quantity of work done will b e measured by the
linear foot. Measurements will be made along the ground parall el to the roadway centerline. Payment for inslope rehabilitation will include excavation and fill areas.
211.08 Basis of Payment Payment will be full compensation for excavating,
removing brush, trees and stumps, placing waste material in des ignated areas, disposing excess materials, rehabilitating waste areas including seed and mulch, and for grading and finishing the work. In inslope rehabilitation areas, any borrow material needed to complete the rehabilitation of the inslopes will not be paid for separately, but will be considered incidental to this item. When rock is encountered in new ditch excavation areas and new ditch excavation rock is not included in the cont ract, the excavation of the roc k will be paid for at 6 times the contract unit price for new ditch excavation. The work will not be accepted for payment until inspected and approved by the Resident or authorized personnel. Conditions of approval will include, but are not limited to, grade and smoothness, flow of runoff, proper functioning of the drainage system, and cleanup of all disturbed areas including waste disposal areas. Seed, mulch, and erosion control blanket applied on the project will be paid for under a ppropriate contract items. 2-41 Payment will be made under: P a y I t e m P a y U n i t
