• Clarifying Load Ratings for Timber Bridges Helps Local Road Agencies
  Posted: Nov 12
  Researchers at the University of Colorado Denver studied timber bridges as well as computer models to determine how two common load rating methods are related.
• Research on Rebar Connections Will Lead to Better Bridges
  Posted: Nov 5
  Researchers at Utah State University studied the connections between steel reinforcement bars embedded in concrete bridges to help bridge designers improve designs for accelerated bridge construction. The construction technique cuts construction time and costs, reduces risk for workers and the traveling public, improves quality assurance, and is more environmentally friendly.
• New Coating Protects Bridge Decks From Vehicle Fires
  Posted: Nov 4
  Utah State University researchers developed a protective coating to safeguard bridge decks overlaid with polymer concrete, a material that is seeing an increased use because of its high bond strength, short curing times, good resistance to water and chlorine penetration, and excellent skid and abrasion resistance.
• Employing Technology to Establish No-Passing Zones
  Posted: Oct 8
  Researchers at the University of Wyoming developed a system for establishing passing zones on rural two-lane highways that is more accurate and more efficient that an existing outdated system. The two-vehicle system uses vehicle-to-vehicle communication, video technology, GPS, speed data and machine vision systems to establish passing and no-passing zones.
