| Abstract: | In view of the fact that the aggregate inter-particle friction could directly affect the shear strength of asphalt mixture, the feasibility utilizing direct shear test to evaluate the friction properties of aggregate was analyzed using analogue principle. Aggregates and steel balls with gradations conforming to AC-13 and SMA- 13 asphalt mixtures were evaluated with direct shear tests. Results of the study solved problems in aggregate shear testing. |
