Progress in asphalt mixture micromechanics research based on discrete element

This thesis describes the latest progress of discrete element in asphalt mixture micromechanics research,specifically describes the modeling method of asphalt mixture discrete element.According to the inadequacies of the current study,it predicts the development direction of asphalt mixture micromechanics based on discrete element,with a view to promote mixture micromechanical study based on discrete element.
