b. Deeper embedment may be required where a toe slope is present or where a leveling pad is specified.

c. Excavate the foundation to a minimum width equal to the specified base rock width, 18 inch minimum, plus 12 inch to include the Free Draining Granular Backfill drain behind the rock wall.

d. Conform to the following:

1) Excavate the foundation in sections such that the rock wall can be constructed in one shift or one day�s work, unless shoring is provided for the purpose to support the excavation.

02378S - Page 5 of 6

2) Exercise care during excavation of the back cut

(temporary cut slope).

2. Compact the foundation using at least three passes of a lightweight, steel, smooth-drum vibratory roller, or as otherwise determined by the Engineer before the wall construction.

3. Remove unsuitable foundation soils and replace with Granular

Borrow, or with other suitable material determined by the Engineer, placed and compacted according to Section 02056.

B. Rock Wall Erection:

1. Place the first course of rock (base rock) on prepared foundation.

As the rock wall is constructed, place the rocks so that there are no continuous joints in either the vertical or lateral direction.

2. Avoid placing rocks which have shapes that create voids with a linear dimension greater than 12 inch.

3. Except in isolated cases, place each rock so that it bears on at least two rocks below it. Locate at least one bearing point a distance no greater than 6 inch from the average face of the rock wall.

4. The allowable tolerance for base rock widths is 6 inch; however, do not place two or more consecutive base rocks with a width less than specified on the plans.

5. Slope the top surface of each rock towards the back of the rock wall at an inclination of at least 5 percent.

6. Construct the exposed face of the rock wall with a face batter of

6V:1H.

7. Securely place rocks so that they are unable to be moved with a pry bar after the rock wall is complete.

C. Voids:

1. Where voids with a linear measurement of 6 inch or greater, in any dimension, exist in the face of the rock wall, chink the voids with smaller rock.

2. If there is no rock contact within the rock wall thickness, chink the void with a smaller piece of rock.

3. Chinking rocks do not provide primary structural support for the overlying rock.

02378S - Page 6 of 6

4. Grout chinking rocks that are able to be moved or removed by hand. Do not allow grout to be readily visible from the face of rock wall.

D. Rock wall Drainage:

1. Install the free draining granular backfill drain between the rock wall and the back cut face being supported. The Free Draining

Granular Backfill drain layer is at least 12 inch thick, measured horizontally from the back of the base rock to the face of the back cut. Place free draining granular backfill drain concurrent with rock wall so that at no time is either more than 24 inch higher than the other.

2. Separate the free draining granular backfill drain from the back of rock wall by separation geotextile. Overlap the separation geotextile at least 12 inch at all seams.

3. Cap the free draining granular backfill drain with at least 12 inch of native, relatively impermeable soil. Place separation geotextile between the native, relatively impermeable soil and the free draining granular backfill drain.
