• Abstract:
  The use of delineators has become popular across
  
  Texas. They are being used in several different
  
  applications with unique impact conditions and/or
  
  impact frequency. There is not a federally mandated
  
  national standard for testing and evaluation of
  
  delineators. For this reason, each state must either
  
  develop personalized evaluation criteria or adopt the
  
  American Association of State Highway and
  
  Transportation Officials (AASHTO) National
  
  Transportation Product Evaluation Program (NTPEP)
  
  evaluation standard.
  
  By developing a categorical testing specification, the
  
  state can better evaluate delineator products for each
  
  application use. This enhanced evaluation would lead
  
  to the proper selection of the best delineator for a
  
  certain application. By pairing delineators with their
  
  proper application, one would expect a reduction of
  
  delineator failures and therefore reduction in long-term maintenance costs.
