• Abstract:
  The ODOT Research News includes: 1) The 2006 Northwest Transportation Conference will be held February 7-9, at the Oregon State University. 2) The annual project solicitation for ODOT’s research program is underway. 3) Living with Cracked Bridges. Oregon has several hundred reinforced concrete deck girder (RCDG) bridges, built in the late 40s to the early 60s, that now exhibit diagonal cracks in the girders. Diagonal cracking in beams has been associated with inadequate shear capacity, a situation engineers design to avoid because it may lead to a sudden failure. Research funded by ODOT and conducted by Oregon State University (OSU) showed that repeated traffic loading was not causing the steel reinforcement to gradually deteriorate; a critical consideration in deciding whether to replace or repair a bridge. The research also defined an accurate method to estimate the load capacity of the cracked girders, which was incorporated into a reliability-based procedure to load rate the cracked bridges. Subsequent efforts have focused on implementing the load rating method for cracked girders, repairing cracked girders, developing an analysis method for cracked bent caps, and deploying bridge monitoring technology. 4) Linking Land Use to Traffic Impacts at Interchanges. 5) ODOT and ODFW Collaborate to Collar Collisions on a Highway Corridor. The Oregon Department of Transportation and the Oregon Department of Fish and Wildlife are partnering on research regarding what is literally an everyday occurrence. Thousands of times a year, deer attempt to cross an Oregon Highway at the same time a vehicle is traveling down the highway. The results are almost always frightening for both the deer and the driver. Frequently these encounters also result in the death of the deer and damage to the vehicle. Less commonly, injury or death of an occupant of the vehicle can also result.
