At all times, ditches and drains along the roadbed shall be cleaned and maintained so as to drain it effectively. In no case shall any base course, surface course, or pavement be placed on a frozen, muddy, or unstable roadbed nor until the roadbed has been checked and approved. Method of Measurement 208.06 Previously Constructed Roadbed. The length of finishing previously constructed roadbed to be paid for will be the number of miles of roadbed measured along the centerline thereof, finished to the required width and accepted, subject to the provisions of subsection 208.07. Basis of Payment 208.07 Previously Constructed Roadbed. When the bid schedule contains an estimated quantity for "Finishing previously constructed roadbed," the quantity, determined as provided above, will be paid for at the contract price per unit of measurement for the pay item listed below, which price and payment will be full compensation for the work prescribed in this section except as provided in (1), (2), and (3) below. (1) Excavation more than 0.3 feet below the existing roadbed surface will be paid for as provided under Section 203. (2) Removal of slide material will be paid for as provided under Section 203. (3) Additional material ordered by the Engineer to bring the roadbed to the finished section will be measured for payment under the applicable sections. When the bid schedule does not contain an estimated quantity for "Finishing previously constructed roadbed," the work will not be paid for directly but will be considered as a subsidiary obligation of the Contractor covered under other contract items. 209.01 General. This work shall consist of gravel, slag, crushed stone, or sand furnished and placed in layers against the inside faces of retaining walls, wing walls, back faces of abutments, and over the extrados of arches, in accordance with these specifications and in reasonably close conformity with the requirements shown on the plans or as directed by the Engineer. Materials 209.02 Sheathing material may be either gravel, slag, crushed stone or sand meeting the requirements of subsection 703.17. Construction Requirements 209.03 When used against a mortar protection course of membrane waterproofing, sheathing shall not be placed until the mortar has aged for at least 3 days. The inlet ends of all weep holes and drains shall be covered first with large selected stones over which there shall be placed finer material in such manner as to provide free access for the drainage but prevent the leaching out of the filling material. The sheathing shall form a continuous covering over the entire designated surface, extending from the elevation of the bottom of weep holes and drains to the top of the wall. It shall be so placed that mingling with the fill will be prevented. Planks or other suitable separators that can be withdrawn as the work progresses shall be kept between the sheathing and the fill when working against vertical faces or slopes steeper than the angle of repose of the material. When waterproofing is protected by roofing felt, a 4-inch layer of sand shall be placed between the coarse graded sheathing and the felt. Unless specific thicknesses are shown or ordered, the layer of sheathing shall have a nominal total thickness of 1 foot. Method of Measurement 209.04 The quantity to be paid for will be the number of cubic yards of sheathing material together with sand when included, measured in final position, between the limits shown on the plans or directed by the Engineer, complete in place and accepted. Basis of Payment 209.05 Payment will be made for the quantity measured as provided above, for the pay item below, which price and payment will be full compensation for the work of this section. Payment will be made under: Pay item 209(1) Sheathing material Pay unit cubic yard. Section 210.-OBLITERATION OF OLD ROADWAYS Description 210.01 This work shall consist of the obliteration, in reasonably close conformity with these specifications, of such old roadways as are shown on the plans or designated by the Engineer for obliteration. Construction Requirements 210.02 After designated sections of the old roadway are no longer needed for traffic, the ditches shall be filled and the roadway rough graded, to restore approximately the original contour of the ground or to produce a pleasing appearance by forming natural, rounded slopes. After the rough grading is completed, the area of the old roadbed shall be scarified or plowed to mix the remaining road surfacing material thoroughly with earth and then the area shall be harrowed and smoothed. Old structures shall be broken down and buried or removed. Where shown on the plans or directed by the Engineer, all material with salvage value shall be carefully removed to avoid damage. Any materials salvaged from the old roadway and meeting specifications for any items of the new roadway may be used in the construction thereof as provided in subsection 106.11. Where shown on the plans or directed by the Engineer, materials required for the new roadway shall be taken from the old roadway, and suitable material taken from the new roadway shall be used in obliterating the old roadway. There will be no separate payments for excavating, backfilling or compacting any remaining cavities. Method of Measurement 210.03 The area to be paid for will be the number of 1000 square foot units of old roadway acceptably obliterated or the square yards of old roadbed acceptably scarified, whichever is called for in the bid schedule. Only those units and fractions thereof which are outside the limits of the new roadway will be measured. Areas of less than 200 square feet will not be measured. Basis of Payment 210.04 The quantity determined as provided above will be paid for at the contract price per unit of measurement for the particular pay item listed below that is shown in the bid schedule, which price and payment will be full compensation for the work prescribed in this section, except that materials obtained from the old roadway and used in construction of the new roadway and materials obtained from the new roadway and used in obliteration of the old roadway will be paid for under Sections 203, 624, or other applicable sections. 211.01 This work shall consist of cleaning up roadside areas in reasonably close conformity with these specifications. The areas to be cleaned up shall be those areas so denoted on the plans or designated by the Engineer which are located beyond the clearing and grubbing limits designated in Section 201. Cleanup shall consist of clearing the designated ground of down timber, dead brush, logs, and debris, the felling and destroying of snags and dangerous trees as ordered by the Engineer within the designated area being cleaned up, and the burning or otherwise disposing of the spoil as ordered by the Engineer. Cleanup shall also include the removal from cultivated or cropped areas of all dead plants and plant refuse and shall include living crop plants when so ordered by the Engineer. Construction Requirements 211.02 The neatness of cleaning up shall be relative, so as to be in character with the surroundings. Hand raking or any similar exaggerated degree of treatment will not be required. Intensity of cleanup shall be gradually diminished from the road prism construction outward to the cleanup limits or boundary designated by the Engineer, so as to effect a natural transition in treatment, and so as to avoid sharp demarcation between the artificial and the natural. As a general guide, the first 20-foot width nearest the roadway shall have practically all small sticks and other loose particles removed, except those of approximately 1 inch or less in thickness or diameter. The second 20-foot width shall be cleaned of substantially all sticks and loose particles exceeding approximately 2 inches in thickness or diameter, and the third 20-foot width shall be cleared of substantially all sticks and loose particles exceeding approximately 3 inches in thickness or diameter. Trees and snags designated for removal shall be cut flush with the ground. Stumps within the areas designated for cleanup shall also be cut flush with the ground. Refuse from cleanup operations shall be disposed of as provided under Section 201. Method of Measurement 211.03 The area to be paid for will be the number of acres and fractions thereof or thousand square feet units and fractions thereof, of land acceptably cleaned up as staked or designated by the Engineer and in accordance with these specifications. Acreage will be computed from dimensions measured horizontally. Basis of Payment 211.04 The quantity determined as provided above will be paid for at the contract unit price per unit of measurement for the pay items listed below that are shown in the bid |
