• Abstract:
  Concrete and aggregates sampled on 20 field visits to Kansas Department of Transportation concrete paving projects constructed between 2010 and 2012 were tested to compare the KTMR-22 freeze-thaw durability of field-cast specimens with standard lab-cast specimens made with the same aggregates. No consistent differences were found between the field and lab specimen results, indicating that the results of the KTMR-22 (2012) Resistance of Concrete to Rapid Freezing and Thawing test are determined primarily by the durability of the aggregate used. Sampling concrete as delivered to the job site for freezing and thawing evaluation would provide assurance that the KTMR-22 test results reflect the performance of the aggregate used in the pavement.
