RISImproved Modeling of Subaerial and Subaqueous Muddy Debris Flows
Publisher: ASCE
Abstract: In this note, a two-dimensional depth-averaged numerical model (MassFlow2D) previously developed to simulate subaerial and subaqueous muddy debris flows is further improved. The retarding effects of ambient fluid, including ...
Skeleton Filling System Evaluation Method of Asphalt Mixture Based on Compressible Packing Model
Publisher: ASCE
Abstract: Asphalt mixtures are composed of skeleton aggregate and filling mortar. Skeleton stability and mortar filling state are of great significance to asphalt mixture performance. First, the aggregate in asphalt mixture is ...
Atomic-Level Insights into the Mechanisms of Reinforcement and Fracture in a Graphene-Reinforced Bitumen Composite
Publisher: ASCE
Abstract: Graphene can significantly improve the mechanical performance and durability of a bitumen composite. However, the underlying reinforcement mechanism of this enhancement is not yet clear. Here, we use molecular dynamics ...
