    Abstract
  • California bearing ratio (CBR) test was simulated by using PFC2D, CBR changing laws of single coarse aggregate, synthetic coarse aggregate and coarse-fine combined aggregate were analyzed, a coarse aggregate skeleton gradation with high interlocked force was put forward, and its performances were verified through laboratory test. Test result shows that the main skeleton structure composed of the aggregate with diameter 19-31.5 mm has high interlocked force, and the optimal mass fraction is 50%-70%. The aggregates with diameter 9. 5-19 mm and 4.75-9.5 mm have the effects of filling the void of main skeleton structure and interfering its composing, and the optimal mass fraction of the aggregate with diameter 4.75-9.5 mm is 10%. When the optimum proportion of coarse aggregate to fine aggregate is 65∶35, the CBR value of coarse-fine combined aggregate reaches the highest point, and is more than 540%. The CBR value and compressive strength of the mixture composed of the coarse gradation are over 1.19 times and 1.10 times than that of standard gradation respectively, so the coarse gradation has better mechanical properties.
