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.
