f. Undercutting

Roadway backslope shall not be undercut.

g. Intersections

1. Intersections with side roads which are not closed or restricted to vehicular use shall be bladed to assure smooth transitions.

2. Field evidence of closure or restrictions shall be considered to be signing, cross ditching in the road surface (traveled way), earth berms or other devices placed to discourage or eliminate use by passenger cars. Also, roads listed for work under Sections 835 or 838 shall be considered restricted.

3. Side roads listed for work under this Section shall be considered as not restricted.

2. Scarification shall be accomplished by rippers spaced not more than

12 inches apart.

3. Scarification shall not penetrate the aggregate base to the subgrade.
