204.05 Preparing Foundation for Embankment: Prepare foundation for embankment construction as follows:

1. Embankment over natural ground. Remove topsoil and break up the ground surface to a minimum depth of 6 inches by plowing or scarifying. Compact the ground surface according to Subsection 204.07.

2. Embankment on an existing slope steeper than 1V:3H. Cut horizontal steps in the existing slope to a sufficient width to accommodate placement and compaction operations and equipment. Step the slope as the embankment is placed and compacted in lifts. Start each step at the intersection of the original ground and the vertical cut of the previous step.

204.06 Embankment Construction: Incorporate only suitable roadway excavation material into the embankment.

1. General: At the end of each day’s operations, shape to drain away from the embankment and compact the embankment surface to a uniform cross-section. Eliminate ruts and low spots that could hold water.

During all stages of construction, route and distribute hauling and leveling equipment over the width and length of each lift of material.

Compact embankment side slopes with a tamping foot roller, by walking with a dozer, or by over building the fill and then removing excess material to the final slope line. For slopes 1V:1¾H or steeper, compact the slopes as embankment construction progresses.

2. Embankment within the roadway prism: Place embankment material in horizontal lifts no more than 8 inches in compacted thickness. Construct the top 12 inches of the embankment using 4-inch minus material. Incorporate oversize boulders or rock fragments into the lower lifts by reducing them in size or placing them individually as required below. Compact each lift according to Subsection 204.07 before placing the next lift.

3. Embankment outside of roadway prism: If placing embankment outside the staked roadway prism, place material in horizontal lifts less than 10 inches in compacted thickness. Compact each lift according to Subsection 204.07.

204.07 Compaction: Compact each layer of material to the in-place density requirements of Table

204-1 for the method of moisture and density control used. Incorporate water to achieve optimum moisture range. Density testing may be performed by BLM personnel at the Contracting Officer’s discretion using a Nuclear Densometer.

Less than 12% air-filled voids

204.08 Sloping, Shaping, and Finishing: Complete slopes, ditches, culverts, riprap, and other underground minor structures before placing aggregate courses. Slope, shape, and finish as follows:

1. Sloping: Leave earth slopes with uniform roughened surfaces with no noticeable break as viewed from the road. Except in solid rock, round tops and bottoms of slopes including the slopes of drainage ditches. Round material overlaying solid rock to the extent practical.

Remove loose or unstable rocks and dress all rock slopes as the excavation process progresses and slopes are still accessible to the equipment.

Do not place topsoil or mulch on slopes until approved. If a shallow landslide occurs on a cut or embankment slope, remove or replace the material and repair or restore damage to the work. Bench or key the slope to stabilize the slide. Reshape the cut or embankment slope to an acceptable condition.

2. Shaping: Shape the subgrade to a smooth surface and to the typicals required. Shape slopes to gradually transition into slope adjustments without noticeable breaks. At culverts, the ends of cuts, and at intersections of cuts and embankments, adjust slopes in the horizontal and vertical planes to blend into each other or into the natural ground.

3. Finishing: Remove material larger than 6 inches from the top 6 inches of the roadbed.

Remove unsuitable material from the roadbed and replace it with suitable material.

Finish roadbeds and ditch cross-sections to maintain proper ditch drainage.

209.05 Compaction: Determine optimum moisture content and maximum dry density according to

AASHTO T 99, Method C. Adjust the moisture content of the backfill to a moisture content suitable for compaction.

Compact material placed in each lift to at least 95 percent of the maximum density. Determine the in place density and moisture content according to AASHTO T 310 or other approved test procedures.

Do not apply density requirements as measured by AASHTO T 310 to material that cannot be tested or compacted to maximum values determined by AASHTO T 99. For this material, fill the voids around the rocky material in each lift with structural backfill or foundation fill as appropriate. Compact each lift until there is no visible evidence of further consolidation.
