215.1 Description. This work shall consist of grading and shaping existing slopes to eliminate shoulder drop off
conditions as shown on the plans or as directed by the engineer.
215.1.1 Shaping Slopes, Class I, shall consist of shaping slopes where, in general, the material required to bring
the roadway to the designated cross section can be obtained or disposed of within 1000 feet on the right of way as directed by the engineer.
215.1.2 Shaping Slopes, Class II, shall consist of shaping slopes where it may be necessary to haul in excess of
1000 feet or go outside the limits of the right of way for additional material to construct the slopes to the designated cross section or where it may be necessary to dispose of waste material outside the limits of the right of way. The contractor shall provide the engineer with an acceptable written agreement with any property owner from whose property additional material is to be obtained or on which excess excavation is to be disposed.
215.1.3 Shaping Slopes, Class III, shall consist of providing fill material and shaping slopes to construct
additional shoulder width for the installation of guardrail and Type A crashworthy end terminals in accordance with Missouri Standard Plans for Highway Construction. Material used shall be Type 1, 5, or 7 Aggregate Base, or other granular material approved by the engineer. Any excess material shall be disposed of outside the limits of the right of way.
215.1.3 1 In lieu of aggregate base, earth material may be used for Shaping Slopes, Class III. When earth
material is used, an approved seed mixture shall be applied in accordance with Sec 805, mulch shall be applied in accordance with Sec 802 and erosion and sediment control shall be utilized in accordance with Sec 806. All cost for seeding, mulching, and erosion control shall be incidental to the cost of Shaping Slopes, Class III.
215.2 Construction Requirements. Slope areas to be shaped by the addition of material shall be scarified to
allow bonding with the added material. Density shall be obtained from reasonable compactive efforts consisting of no less than three passes with a roller or other methods approved by the engineer. The contractor will not be required to excavate any classified rock excavation under this item.
215.2.1 Benching of the existing slope may be necessary to provide stability to the additional shoulder width
constructed by Shaping Slopes, Class III. All costs for benching shall be included in the cost of Shaping Slopes, Class III.
215.3 Method of Measurement. Final measurement will not be made except where appreciable errors are
found in the contract quantity.
215.3.1 Where required, measurement will be made to the nearest 1/10 station separately for each length of
slope measured along the centerline of the traveled way and totaled to the nearest 100 feet for the sum of all segments.
215.3.2 Shaping Slopes, Class I, Class II, or Class III will apply only to those sections that have been
specifically designated as such on the plans.
215.4 Basis of Payment. The accepted quantity of shaping slopes will be paid for at the contract unit price for
each of the pay items included in the contract. If Shaping Slopes, Class I, Class II, or Class III is not provided but is required, payment will be in accordance with Sec 104.3. No direct payment will be made for any additional material required for shaping slopes.
