| Abstract: | The shape of coarse aggregate has great influence on the mechanical strength of asphalt mixture. Based on three indexes of aggregate shape, the triaxial shear test and the wheel tracking test can be used to determine the optimum shape of coarse aggregate which makes the strength of asphalt mixture to the greatest value. It can provide theory for production of detritus mine material. |
| Keywords: | road engineering shape of coarse aggregate shear stress dynamical stability |
