Laboratory data were gathered by using a stripping test that is being developed and evaluated under NCHRP Project 4-8(3)/1 and is expected to be adopted for use in the state of Virginia. The testing program included a determination of the significant influences of different brands of asphalt cement and antistripping additives on the susceptibility to stripping of asphaltic concrete. Aggregates from eight sources, three asphalt cements, and two antistripping additives were used in various combinations. The results indicate that the new test method measured no significant differences in the stripping susceptibility of mixes with different asphalts. In one of the three mixes in which the effect of the type of additive was determined, a significant difference was found. Results of supplementary tests with a modified version of the test method indicate a good correlation with those obtained by use of the original method. It is concluded that the new method can probably be simplified to allow the use of equipment now available in district materials laboratories in Virginia. /Author/
