Overview

Simulation explores mechanical properties in asphalt mixtures, suggesting impacts on pavement design.

Key Points

  • This study aims to simulate dynamic modulus tests of asphalt mixtures to understand their mechanical behaviors.
  • Simulated dynamic modulus tests using three-dimensional discrete element method (DEM)
  • Constructed fine-grained AC-13 and medium-grained AC-20 asphalt mixture models
  • Predicted dynamic modulus and phase angle values
  • Validated model by comparing simulations to laboratory experiments
  • Investigated effects of temperature and loading frequency on dynamic modulus
  • 3D DEM model accurately predicts dynamic modulus and phase angle of asphalt mixtures
  • Temperature and frequency significantly influence dynamic modulus
  • Increasing gradation impacts loading-bearing ratio due to coarse aggregate proportion
