Two 3-lane feeder roads to Beltway Eight, one of Houston, Texas's busiest perimeter highways, needed restoration due to severe spalling. The Texas Department of Transportation (DOT) had to rehabilitate the worn roads, but time was a major concern. The Beltways and feeder roads, which are about 12 years old, have stood up fairly well under heavy use. Upon inspection, it was determined that the base of the existing pavement was in satisfactory condition and could remain in place. However, the top 2 inches of pavement was damaged due to spalling caused by alkali-silica reactivity (ASR). This article describes efforts by the Texas DOT to deal with this top layer ASR corrosion with a thin bonded concrete overlay. A previously used method of steel fiber reinforcement was added to the concrete overlay for added strength. The installation process and advantages of this type of pavement rehabilitation are also described.
