Criteria relating LPR readings to deterioration rates similar to the ASTM C876 criteria for reference electrode potentials have been published (Broomfield et al., 1993). These show some comparability between different devices and will be discussed later under interpretation (Section 4.12.4). A set of conversion equations is provided in the final report of the Strategic Highway Research Program (SHRP) contract on corrosion rate measurement (Fliz et al., 1992).

Pneumatic hammers are labour intensive but have low capital cost and are very versatile. They will cut behind the bars and get between them. Research by the Strategic Highway Research Program (SHRP) has shown that the contract terms for a repair job are a major influence upon the contractor s decision as to how concrete removal is done (Vorster, 1992). If concrete removal is in small areas, pneumatic hammers are more practical than the larger plant such as hydrojetting or milling equipment discussed later. If the area of concrete to be broken out undefined at the tender stage and the contractor is paid by the square metre (or cubic metre) there is less risk with a low capital cost approach like pneumatic hammers.

The very first trials of this system were based on a rapid treatment period of 12-24 hours. Trials were done in Ohio, United States, and lab tests in Kansas Department of Transportation in 1976 (Morrison et ah, 1976, Slater et al., 1976). However, a more fundamental study carried out by the Strategic Highway Research Program (SHRP) in 1987-1992 (Bennett et al., 1993a,b) showed dangers in applying more than 4 A-m of steel or concrete surface area. Current treatment times are now measured in weeks rather than days.

The extensive Strategic Highways Research Program, completed in the United States in 1993, concluded in performance graded (PG) specifications for bitumens (asphalt binders) known as Superpave (superior performing pavements) specification. These specifications were first introduced by Asphalt Institute (Asphalt Institute SP-1) and soon became an AASHTO standard (AASHTO M 320) and ASTM standard (ASTM D 6373 2007). 

The test is usually conducted at 20°C. However, the test may be conducted at the effective test temperature for equivalent pavement fatigue damage using the equation developed during the Strategic Highway Research Program ...
