Abstract : The research documented in this report represents an effort to evaluate the test procedures for coal tar mixtures. The various coal tar test methods have been evaluated under several levels of test variables. The freeze- thaw and scuff resistance tests were evaluated under three types of shingles and an aluminum substrate. The fuel resistance test was evaluated under three levels of sand loading and three levels of film thickness. In addition, all of the tests were evaluated under two levels of humidity. The analysis of the data indicates that the effect of the substrate is insignificant in all of the tests. The effect of humidity is significant on some tests, while the effects of sand loading and film thickness are highly significant on the results of the fuel resistance tests....
