Evaluation of the Frost Resistance of Roller-Compacted Concrete Pavements
An investigation was conducted to evaluate the frost resistance of samples taken from roller-compacted concrete (RCC) pavements using laboratory testing procedures. Nine existing pavements were sampled and tested for microscopical determination of air-void content and parameters of the air-void system, resistance to rapid freezing and thawing, critical dilation, and compressive and flexural strength. The pavements ranged in age from 1 month to 8 years at the time of sampling. Preliminary results of the dilation tests indicate that those samples judged to be frost susceptible when tested by rapid freezing and thawing, may, in fact, offer some degree of frost resistance. The dilation test may be appropriate, therefore, to determine whether a RC sample is frost resistant at the time of test or to measure the period of frost immunity.
