Concrete Barrier Distress in La Grande, Oregon

Several precast concrete barriers in eastern Oregon were noted to be deteriorating at an advanced rate. The Oregon Department of Transportation Research Unit took several core samples from the barriers and conducted analyses. Petrographic evaluations determined that the strongest link between barrier deterioration and any one factor was the amount of entrained air. In general, older, poor-quality concrete, which was continually exposed to freeze-thaw events, exhibited advanced signs of distress.
