Construction Requirements

208.02 New Roadbed. After the roadbed has been substantially completed, the full width shall be conditioned by removing any soft or other unstable material that will not compact properly or serve the intended purpose. The resulting areas and all other low sections, holes, or depressions shall be brought to grade with suitable selected material, provided under Section 203 or Section 305. The entire roadbed shall then be shaped and compacted as provided under Section 203. Scarifying, blading, dragging, rolling, or other methods of work shall be performed or used as necessary to provide a thoroughly compacted roadbed shaped to the grades and cross sections shown on the plans or as staked by the Engineer.

The finished roadbed shall be continuously maintained in a condition suitable for traffic until the next course, if any, of material is placed or until final completion of the work, as the case may be.

208.03 Shoulders. When the plans provide for the construction of a base and/or surface course and the construction of shoulders using materials from roadway and borrow excavation, the shoulders shall be constructed to line, grade, and cross section as provided in subsection 208.02 above. Where the plans provide that the shoulders shall be constructed of other materials, the shoulders shall be constructed as provided for in the plans and specifications for the other materials.

Completed shoulders shall be true to alinement and grade and shaped in reasonably close conformity with the section shown on the plans. They shall be cleaned of any accumulations, reconditioned as necessary, and maintained until final acceptance.

Any high places in the roadbed shall be cut to grade and the resulting material hauled and deposited on low areas or on fill slopes as directed by the Engineer. Should there remain any depressions or narrow embankments, sufficient approved material shall be obtained and placed to bring the width and/or surface of the roadway in reasonably close conformity with the lines, grades, and cross sections shown on the plans or established by the Engineer. The roadbed shall then be rebladed and reshaped. At intersections, the roadbeds of side roads shall be treated similarly, for the distances ordered by the Engineer or as governed by the grading performed, to provide for proper joining of the proposed and existing riding surfaces. The roadbed shall be compacted as provided in subsection 203 and all work that may be necessary to produce a completed and acceptable foundation shall be performed and the roadbed shall be in this specified condition at the time of placement of any base course, surface course, or pavement.

208.05 Protection of Roadbed. 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 New Roadbed. Finishing new roadbed and shoulders will not be measured for direct payment.

208.07 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 subsecti 208.09.

Basis of Payment

208.08 New Roadbed.

(1) Excavation more than 0.3 feet (91 mm) 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 unde 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.
