SHRP The Strategic Highway Research Program. A 150 million research effort that spent about 10 million on corrosion of reinforced concrete bridges suffering from chloride induced corrosion. SHRP produced about 40 reports covering assessment, repair and rehabilitation methodology. All reports can be downloaded from the www.trb.org website... 

As for the rehabilitation design with concrete (PCC) overlays that can be analysed by MEPDG, again seven options are covered, which are shown in Table 15.21. 

A detailed rehabilitation (overlay) design process for concrete (PCC) of flexible and rigid pavements for each of the above cases is covered in the MEPDG (AASHTO 2008). 

The structures programme was entirely concerned with corrosion of reinforced concrete bridges suffering from salt induced corrosion. Its work on structures covered physical assessment, cathodic protection, electrochemical chloride removal, physical and chemical methods of rehabilitating bridge components and a methodology of bridge... 

Concrete Bridge Protection and Rehabilitation Chemical and Physical Techniques—field Validation. Covers the field application and short-term corrosion performance of six trial installations of two inhibitor-modified concrete systems. The installations were applied to both deck and substructure components in a range of environments. Both pre- and posttreatment corrosion assessments v/ere performed to estimate the corrosion performance of inhibitor mcdified concrete systems, including visual inspections, delamination surveys, cover depth sur eys, chloride contamination levels, corrosion potential measurements, and corrosion current measurements. 67 pages. SHRP-S-658... 

The rehabilitation or upgrading of concrete infrastructures by externally bonded FRP composites is a well-established technique developed in the 1990s. It is considered to be an efficient and inexpensive alternative to the replacement of damaged or structurally deficient RC elements. This method covers several specific applications ... 

Abstract This chapter continues the discussions of the development of advanced polymer composite material applications associated with bridge engineering. It focuses on the rehabilitation of metallic bridge structures, all-FRP composite bridges and bridges built with hybrid systems. Chapter 16 covered the materials used in FRP composites, in-service properties and applications of FRP composites in bridge enclosures, the rehabilitation of reinforced and prestressed concrete bridge beams and columns.
