NOTE:

1. Replace unsuitable material according to Subsection 204.07 unless otherwise specified.

2. Minimum subexcavation dimensions are 6 ft wide x 6 ft long.

3. Do not place backfill material within the structural section.

4. Widen top of subexcavation area to allow for bench width in bottom layers. Provide a 1 ft min. bench width for every 2 ft of subexcavation depth.

5. Daylight to drain when the excavation is within 4 ft of the subgrade hinge point. Slope the excavation bottom 2% toward the daylight for drainage, or match the existing roadway cross slope when steeper than

2%.

6. At daylight locations, match the existing fill slope or make slope adjustments to match the subgrade hinge point. Do not construct slopes steeper than 1V:2H unless approved by the CO.

7. Furnish geotextile filter type conforming to subsection 714.01(a). See
