Abstract: The grain size of aggregate particles is crucial to the mixture gradation of discrete-element (DE) models when realistic aggregate shapes are simulated. The objective of this study was to answer the question of how to ...

Abstract: Based on the general Marshall design method for asphalt mixtures, the difference of asphalt mixture density was determined according to the mechanical design method and volume design method. To improve the control accuracy ...

Abstract: In the field, the workability and compactability of asphalt mixtures are essential to obtain the desired smoothness and sufficient density of a compacted pavement, especially for the asphalt mixtures prepared at low ...

Abstract: With the use of intelligent aggregate (IA) and discrete element method (DEM), a method was proposed to predict the influence of aggregate motion on the rutting depth in asphalt mixtures. The IAs were embedded in the center ...
