Description
This report represents data obtained through a comprehensive field study encompassing some 70 bridge decks with a variety of protection systems in place and subject to varying traffic volumes and conditions of exposure. Decks repaired also exhibited varying initial condition and extents of concrete removal prior to rehabilitation.
The basic categories of protection systems under study are as follows:
1. Membrane and bituminous overlay.
2. Special concrete overlays.
3. Coated rebar systems.
Primary testing of these systems consisted of:
1. Delamination/debonding surveys.
2. Clear cover measurement.
3. Half cell potential testing.
4. Chloride penetration testing.
5. Visual surveys.
The criteria followed for evaluation of system performance were separated into two elements:
1. System effectiveness (how well i.t does its job).
2. System durability (how., long it performs under service conditions
