200-28 Section 205 — Embankment Construction
205.1 Description 1 Prepare embankment foundations , and place and compact approved material in embankments. Dispose of unsuitable material. 205.2 Materials 1 Construct embankments with materials meeting the requirements of Sections 203 and 204. 205.3 Construction 205.3.1 General 1 Comply with the provisions of project permits that limit the surface area of the exposed erodible material. 2 Perform work under this Section that ensures compliance with Subsection 107.24 . Conduct operations consistent with good erosion control practices that minimize soil erosion and, as practical, that prevents sediment from leaving the site. Take all measures necessary to control erosion and to minimize the transportation of sediment into adjacent watercourses, wetlands, and impoundments throughout the life of the project. 3 To limit the surface area of erodible material exposed, the RCE may require that partially completed slopes be graded to the specified slope and that seeding be performed at that time according to Section 810. 4 Do not place rocks, broken concrete, or other solid materials in embankment areas where piling will be driven. Do not construct the top 6 in. of embankments with any material larger than can pass a 3- in. sieve. 5 Use all suitable site- excavated material for the formation of embankments, subgrade, shoulders, approaches, intersections, and drives and for backfilling around structures. Perform the work in a manner and sequence with selective grading and necessary cross hauling so that the most suitable soil is reserved for topping the embankments. 6 Maintain the embankment as provided in Subsections 104.7 and 205.3.7 . 7 Complete all clearing and grubbing according to Section 201. Fill and compact stump holes and depressions before proceeding with the embankment construction. 8 Construct embankment by placing, spreading, and compacting the material in successive, uniform, horizontal layers of not more than 8 in. in depth (loose measurement) for the full width of the cross section, except as specified in Subsection 205.3.3 where the depth may exceed 8 in. Perform compaction
