A Primary Mission of the Council is to promote effective means of surface preparation in the maintenance industry using water and water/abrasive blasting techniques. Abrasive blasting is one of the oldest and most popular surface preparation methods used in the bridge painting industry. Recyclable Steel Grit (RSG) blasting is very similar to expendable abrasive blasting …

Deploying Resourses in Rapid Bridge Repairs
On many highway overpasses, bridge painting is an inconvenience to the travelling public as well as a safety hazard. Therefore, a concept called “Rapid DeploymentSM” has been developed to reduce these inconveniences and hazards. The main objective of the concept is to mobilize all equipment to the site, blast and paint, and incrementally demobilize all …

Tape Coating and Testing Results
A Primary Mission of the Council is to promote effective means of surface preparation in the maintenance industry using water and water/abrasive blasting techniques. The tape coating was tested in a series of accelerated and outdoor exposure tests in comparison to a moisture cured polyurethane coating system. The testing included ASTM B117 salt fog, scratch …
Thermal Spray Coatings
A Primary Mission of the Council is to promote effective means of surface preparation in the maintenance industry using water and water/abrasive blasting techniques. Metallizing is a type of thermal spray coating (TSC) that produces a durable metal coating. The TSC metal typically applied to steel structures such as highway bridges is either pure zinc …
ElectroStrip(TM) Technology
A Primary Mission of the Council is to promote effective means of surface preparation in the maintenance industry using water and water/abrasive blasting techniques. An electrolyte is contained in a liquid-absorbent material to which a counter electrode is attached. This apparatus, often combined with a liner, is attached to the painted metal surface (typically steel) …
Blasting and Waste Disposal
A Primary Mission of the Council is to promote effective means of surface preparation in the maintenance industry using water and water/abrasive blasting techniques. Costs for hazardous waste disposal are more than double that of non-hazardous waste disposal costs.1 This, combined with the liability involved with hazardous waste disposal has brought other options to the …
Abrasive Injected Water Blasting
A Primary Mission of the Advisory Council is to promote effective means of surface preparation in the maintenance industry using water and water/abrasive blasting techniques. The Abrasive Injected Water Blasting (AIWB) process involves introducing an abrasive into a high pressure water stream where it is delivered to the surface to be blasted. AIWB will impart …
Water/Abrasive Systems in Cleaning and Profiling
Slurry blasting and surfaces. This slurry material is forced through the blast hose to the nozzle using compressed air, similar to the method used to move dry abrasive through hoses in conventional abrasive blasting operations. However, the Torbo® system allows the blast operator to control the following directly at the nozzle: abrasive mixture quantity, air …
