• Abstract:
  Pavement marking technology is a continually evolving subject. There are numerous types of
  
  materials used in the field today, including (but not limited to) paint, epoxy, tape, and
  
  thermoplastic. Each material has its own set of unique characteristics related to durability,
  
  retroreflectivity, installation cost, and life-cycle cost. The Iowa Highway Research Board was
  
  interested in investigating the possibility of developing an ongoing program to evaluate the
  
  various products used in pavement marking. This potential program would maintain a database
  
  of performance and cost information to assist state and local agencies in determining which
  
  materials and placement methods are most appropriate for their use.
  
  The Center for Transportation Research and Education at Iowa State University has completed
  
  Phase I of this research: to identify the current practice and experiences from around the United
  
  States to recommend a further course of action for the State of Iowa.
  
  There has been a significant amount of research completed in the last several years. Research
  
  from Michigan, Pennsylvania, South Dakota, Ohio, and Alaska all had some common findings:
  
  white markings are more retroreflective than yellow markings; paint is by-and-large the least
  
  expensive material; paint tends to degrade faster than other materials; thermoplastic and tapes
  
  had higher retroreflective characteristics.
  
  Perhaps the most significant program going on in the area of pavement markings is the National
  
  Transportation Product Evaluation Program (NTPEP). This is an ongoing research program
  
  jointly conducted by the American Association of State Highway and Transportation Officials
  
  and its member states. Field and lab tests on numerous types of pavement marking materials are
  
  being conducted at sites representing four climatological areas. These results are published
  
  periodically for use by any jurisdiction interested in pavement marking materials performance.
  
  At this time, it is recommended that the State of Iowa not embark on a test deck evaluation
  
  program. Instead, close attention should be paid to the ongoing evaluations of the NTPEP
  
  program. Materials that fare well on the NTPEP test de cks should be considered for further field
  
  studies in Iowa.
