• Abstract:
  Alkali-silica reaction (ASR) remains a significant durability concern in concrete pavements, leading to internal cracking, surface deterioration, and loss of ride quality. Although preventive measures have reduced ASR in new construction, pavements built in Minnesota in the 1980s and 1990s continue to exhibit distress. This study evaluates maintenance and rehabilitation strategies using historical Ride Quality Index (RQI) and Surface Rating (SR) data, field inspections, and ultrasonic tomography imaging.
