• Abstract:
  ODOT uses a number of pavement marking
  
  materials including waterborne and alkyd traffic paint,
  
  polyester, thermoplastic, preformed tapes, epoxy, and
  
  heat-fused preformed thermoplastic; which are
  
  addressed in ODOT Construction and Material
  
  Specifications (C&MS) Items 640 and 740. Material
  
  selection is presented in Table 397-1 of the 2002 Traffic
  
  Engineering Manual (TEM), whereby the material type
  
  is chosen according to the remaining life of the
  
  pavement surface, type of line (longitudinal line or
  
  auxiliary), type of pavement surface (asphalt or
  
  concrete), and average daily traffic (ADT). According to
  
  this table, durable markings such as thermoplastic and
  
  epoxy are more likely to be applied on highways with
  
  high traffic volumes and pavements with a remaining
  
  surface life in excess of four years, while non-durable
  
  markings such as traffic paint and polyester are
  
  recommended for restriping. Furthermore, thermoplastic
  
  markings are specified for new asphalt pavements and
  
  epoxy markings are specified for new concrete
  
  pavements. This constraint, however, has significant
  
  financial impacts on projects that include concrete
  
  bridge decks connected to mainline asphalt pavements.
  
  The additional cost in such projects is resulted from
  
  paying the contractor an extra cost to use thermoplastic
  
  for the asphalt portion and epoxy for the concrete
  
  portion, or from dividing the project into two separate
  
  projects; one for the asphalt and another for the concrete.
  
  Due to these financial concerns, thermoplastic,
  
  which has poor durability on concrete surfaces, is
  
  currently being applied onto the concrete bridge decks as
  
  well as the mainline asphalt pavements. This often
  
  results in premature debonding in the bridge stripes
  
  compared to those on the adjoining asphalt pavement.
  
  This deficiency raises major safety concerns
  
  regarding these bridges, and leads to low
  
  performance ratings as measured using various
  
  performance indicators in force by ODOT.
  
  As a result, ODOT invited the pavement
  
  marking industry to provide alternative marking
  
  materials and/or installation techniques to be
  
  tested on Portland cement concrete bridge decks
  
  along interstate I-71 in District 3; and initiated
  
  this project to evaluate the performance of the
  
  proposed materials.
