• Abstract:
  Currently, no standard mix design procedure is available for CIR-emulsion in Iowa. The CIR-foam mix
  
  design process developed during the previous phase is applied for CIR-emulsion mixtures with varying
  
  emulsified asphalt contents. Dynamic modulus test, dynamic creep test, static creep test and raveling test
  
  were conducted to evaluate the short- and long-term performance of CIR-emulsion mixtures at various
  
  testing temperatures and loading conditions. A potential benefit of this research is a better understanding
  
  of CIR-emulsion material properties in comparison with those of CIR-foam material that would allow for
  
  the selection of the most appropriate CIR technology and the type and amount of the optimum
  
  stabilization material. Dynamic modulus, flow number and flow time of CIR-emulsion mixtures using CSS-
  
  1h were generally higher than those of HFMS-2p. Flow number and flow time of CIR-emulsion using RAP
  
  materials from Story County was higher than those from Clayton County. Flow number and flow time of
  
  CIR-emulsion with 0.5% emulsified asphalt was higher than CIR-emulsion with 1.0% or 1.5%. Raveling
  
  loss of CIR-emulsion with 1.5% emulsified was significantly less than those with 0.5% and 1.0%. Test
  
  results in terms of dynamic modulus, flow number, flow time and raveling loss of CIR-foam mixtures are
  
  generally better than those of CIR-emulsion mixtures. Given the limited RAP sources used for this study,
  
  it is recommended that the CIR-emulsion mix design procedure should be validated against several RAP
  
  sources and emulsion types.
