TEXAS FREEZE-THAW PEDESTAL TEST FOR EVALUATING MOISTURE SUSCEPTIBILITY FOR ASPHALT MIXTURES

This report describes the Texas Freeze-Thaw Pedestal Test and a preliminary test procedure to distinguish between aggregate-asphalt combinations which are susceptible to moisture damage, such as stripping, and those which are not. The test is basically a modification of the Water Susceptibility Test proposed by the Laramie Energy Technology Center. A guide to the use of this procedure to evaluate both existing and proposed mixtures is included along with the results of a small study to demonstrate the ability of the test to differentiate between known stripping and nonstripping asphalt mixtures.
