3.4 Excavation—Excavate in accordance with Section 208 of the Federal Highway Administration’s (FHWA) FP-14 standards.

• Bed for Granular Borrow: Excavate per plans. Place Granular Borrow as specified above (3.3).

• Concrete toe wall: Excavate as required to achieve the finished height indicated in plans. Form outside face in straight line. Place rebar as shown.

Finish any exposed surface that could be walked on with rough non-slip texture to match ramp. Finish exposed corners with ¾” chamfer.

3.5 Concrete Surfacing — Concrete must be properly worked, placed, consolidated, screeded and bull floated so the aggregate is about a half-inch below the surface.

Concrete surface shall be finished with a surface rough enough to provide good traction, even when covered with algae. Contractor shall create traction grooves in the fresh concrete for traction as follows:

• Latitudinal (i.e. “short direction”) or diagonal orientation
