摘要：

Wilhelmy plate method and sessile drop method were chosen from current existing test methods to evaluate asphalt surface energy with considering operation possibility. The theory, procedure, condition, and the data of the two methods were comparatively analyzed. The influence of test condition on the results of surface energy parameter was discussed based on experimental results of Wilhelmy plate method. The results show that both Wilhelmy plate method and sessile drop method are feasible. However, Wilhelmy plate method performs better in the aspects of sample preparation, temperature controlling, droplet quantity controlling, and the validity of experimental data, so it is recommended to be used for testing the surface energy of asphalt. The surface energy of asphalt mainly depends on Van der Waals force for the sake of low acid-base force. The test procedure and conditions will significantly affect the results of surface energy parameter. It is recommended that the temperature of preservation is 120℃ for about 2 h, the testing time is 2060 s, and the conditioned time is no longer than 3 d when using Wilhelmy plate method. © 2017, Editorial Department of Journal of Building Materials.
