assessment, Continuously reinforced concrete, corrosion, mitigation, South Dakota
Between 1995 and 2009, the SDDOT replaced over 250 miles of two-lane interstate with continuously reinforced concrete pavement (CRCP). After being in service for less that 15 years, several of these pavement sections showed signs of distress. Research was necessary to assess the extent of reinforcement corrosion in SD CRCP interstates. The purpose of this research was to determine the character, extent, and severity of corrosion in CRCP constructed since 1995. Also, identify factors that contribute to observed levels of corrosion; and investigate cost-effective maintenance and rehabilitation mitigation stretegies so that the service life of the pavements may be acheived.
