FFY 2005 Research Projects
NETC 05-2 (Phase 1)
PROJECT TITLE: Enhancing the Reflectivity of Concrete Barriers
PRINCIPAL INVESTIGATOR(S): Scott Civjan, University of Massachusetts, Amherst
PI E-Mail: civjan@ecs.umass.edu
STATUS: This project will be compared against the 2012 Research Need Statements to determine if the research is still a priority for the NETC
ANTICIPATED COMPLETION: To be determined
PROJECT OBJECTIVES: The overall objective of this research is to identify multiple methods for increasing the long-term visibility of concrete barrier systems. These methods must be effective under poor weather and/or nighttime driving conditions. The resulting concrete barriers must be cost effective and their effectiveness must be long lasting with minimal deterioration in effectiveness (safety and visibility) through time and weathering.
NETC 05-5 (FHWA)
PROJECT TITLE: New England Transportation Consortium (NETC) Research Study 05-5: Measurement of Adhesion Properties Between Topcoat Paint and Metalized/Galvanized Steel with Surface Energy Measurement Equipment
PRINCIPAL INVESTIGATOR(S): Sze Yang, PI, and K. Wayne Lee, Co PI, University of Rhode Island
PI E-Mail: syang@chm.uri.edu
STATUS: Active-FHWA
ANTICIPATED COMPLETION: 12/31/2012
PROJECT OBJECTIVES:
- Compare the adhesion properties of NEPCOAT-approved topcoat paint over metallizing to topcoat paint over galvanizing using specialized "surface-energy" measuring lab methods. As a control the adhesion properties of topcoat paint over zinc primer painted steel substrates will also be measured.
- Investigate various factors affecting the adhesion of topcoat paint over galvanizing.
- Report and recommend practices which produce the best adhesion of NEPCOAT-approved topcoat paints over metallized and particularly galvanized steel surfaces. Examine surface cleaning, phosphating vs. wash primer.
