• Description:
  Air-cooled blast furnace slag has been used as a coarse
  
  aggregate in portland cement-based pavement concretes
  
  since at least the early 1900’s. Many of these concretes
  
  have performed satisfactorily. In recent times a number
  
  of PCC slag aggregate pavements constructed in
  
  Michigan in the early 1990’s have shown extensive
  
  cracking and joint deterioration after only ten years or so
  
  of service. The nature of this pavement distress is
  
  described as being unique to the slag aggregate
  
  concretes. This situation prompted a number of field
  
  and laboratory studies, which are cited in the present
  
  report. Currently there is an on-going FHWA study of
  
  this distress issue.
  
  Four slag aggregate concrete pavements in District 12
  
  (Cleveland) of the ODOT system currently show
  
  evidence of the same type of unique distress. Cores
  
  taken from these pavements were petrographically
  
  examined in Phase 3 of the present Forensic
  
  Investigation. The findings are of direct value to ODOT
  
  and provide additional input and insights for the FHWA
  
  study.
