• Abstract:
  Current AASHTO provisions for load rating flat-slab concrete bridges use the equivalent strip
  
  width method, which is regarded as overly conservative compared to more advanced analysis
  
  methods and field live load testing. It has been shown that live load testing of bridges can
  
  provide more accurate responses and can be used to calculate less conservative load rating
  
  factors. Amer et al (1999), Jáuregui et al. (2010), Poulin (2012) and Saraf (1998) have all
  
  demonstrated the benefits of non-destructive testing for the load rating of flat-slab concrete
  
  bridges.
  
  This document is a guide that provides additional recommendations on accepted AASHTO
  
  procedures and for live load testing of flat-slab concrete bridges. Sections 2 – 6 give specific
  
  recommendations in addition to those in the AASHTOs Manual for Bridge Evaluation
  
  (AASHTO 2008). Section 7 provides an example of a report for a live load test that was
  
  conducted on Bradford Bridge #3430 (Poulin 2012).
