【 摘 要 】

In order to evaluate the shear performance of asphalt mixtures with different gradation types, two kinds of substances, glycerol and asphalt, were used as the media of mixture for triaxle test. The test results show that the shear performance of the mixture is greatly influenced by the gradation of the mixture. It also shows that the more the gradation structure is embedded and squeezed, the greater the internal friction angle, the stronger the shear resistance, and by improving the performance of the cementing material can also improve the shear resistance of the mixture.
