According to the Michigan Test Method MTM 115, the results of freeze-thaw tests of aggregates are computed from expansion values recorded at the termination of testing. Intermediate expansion measurements obtained throughout the testing cycle are recorded but not used in the final computation of expansion. A graphical analysis procedure including these measurements revealed that the freezing and thawing produced expansions that follow exponential, power, and linear correlations. The expansions computed by the standard procedure were shown to closely match values predicted by the graphs.
Damage to concrete pavements caused by freeze-thaw deterioration of concrete aggregate remains a serious problem. Current tests for determining an agg...
