Mitigation of Corrosion in CRC Pavement

The CRC pavements constructed as part of the original Interstate system in South Dakota have performed extremely well and exhibited virtually no problems with steel reinforcement corrosion. These pavements had typically tight surface cracks and no spalling and were subjected to a minimum of deicing chemicals over their lives. Comparable pavements in Minnesota, where the use of deicers was several orders of magnitude greater than in South Dakota, provides a cautionary tale of what can happen when corrosion occurs in CRC. Most of these Minnesota CRC pavements had to be replaced within a decade of construction as maintenance became impracticable. The demand for more aggressive winter maintenance, coupled with an increase in usage of solid sodium chloride and concentrated magnesium chloride deicers, means that the newer CRC pavements will be exposed to a much greater level of corrosion-inducing chloride than their predecessors. This research project is necessary to determine the extent of the problem at present and develop strategies to mitigate any corrosion issues before they can result in a significant reduction in service life.
