- Abstract:
- When designing the gradation of asphalt mixture, the practice of first preparing the grading and then conducting performance tests to determine the optimal gradation lacks scientific theoretical basis. Therefore, the basic theory of particle flow is used to simulate the motion law of mixed material particles, the linear contact model of particle flow program is applied, the particle microscopic characteristic parameters and model size are given, the CA0.2, CA0.4, CA0.6 and CA0.8 grads are simulated for contact, and the particle contact force network diagram is drawn, and the simulation results show that the particle contact force of CA0.4 and CA0.6 is relatively uniform, the mixture has good contact force, has good stability during construction, and is not easy to roll. The situation of graded CA0.2 and CA0.8 is the opposite, which provides a certain indoor simulation basis for the grading design of asphalt mixture.
