• Abstract:
  Microsurfacing is a unique pavement preservation tool in the arsenal of maintenance agencies. It is known to
  
  perform well when applied to the right pavement at the right time for the right distress. In order to ensure
  
  microsurfacing performs well, an agency must know what constitutes the right road, right time and right
  
  distress. Texas uses microsurfacing and wishes to answer these questions as well as uncover other factors
  
  leading to successful use of this treatment.
  
  This report describes the current state of practice of microsurfacing in Texas and compares it to best
  
  practices extracted from existing literature. A survey of DOT personnel, contractors and emulsion suppliers
  
  in Texas provides insight into the most crucial factors contributing to the success or failure of a
  
  microsurfacing. From the results of the survey, literature reviews, case studies and site visits, the research
  
  team analyzed material selection and mix design methods, construction practices, equipment practices and
  
  performance measures for microsurfacings. It was concluded that project selection is the most important
  
  contributor to a successful microsurfacing followed by construction practices. Reliance on contractors for
  
  input into proper project selection places the agency in a vulnerable position. A certification course to
  
  educate personnel is recommended.
