1 AASHTO/NTPEP Polymer Concrete Overlays for Bridges and Pavements (PCO)

2 Alphabet Soup  AASHTO – American Association of State Highway Transportation Officials  NTPEP – National Transportation Product Evaluation Program  e-PEF – Electronic Product Evaluation Form  PCO – Polymer Concrete Overlays

3 Purpose  Develop and Implement a Nationally Standardized Performance Based Evaluation Process for Polymer Concrete Overlay Systems  Reduce Redundancy of Testing  Produce Valuable Unbiased Data
