  2. Straightedging (spec. ref.)
    1. Inspect bridge deck and approach slab surface. It should not vary by more than 4 mm (1/8 inch) measured from bottom of straightedge.
    2. Vertical steps at ends of decks and approach slabs shall not exceed 5 mm (3/16 inch).
    3. Expansion joints shall be placed from 2 to 5 mm (1/16 inch to 3/16 inch) below grade.
    4. Inspect entire deck for excess roughness, plastic shrinkage cracking, or surface tearing.

    6. Removal of slurry shall be continuous and immediate.
  4. Penetrating Water Repellent
