RISA Dynamic Model for Ice-Induced Vibration of Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A dynamic model for the ice-induced vibration (IIV) of structures is developed in the present study. Ice properties have been taken into account, such as the discrete failure, the dependence ...
Exploring Factors Contributing to Pedestrian Injury Severity in Pedestrian–Vehicle Crashes: An Integrated XGBoost–SHAP, Latent Cluster, and Mixed Logit Approach
Publisher: American Society of Civil Engineers
Abstract: Everyone faces the risk of road safety, making the precision in predicting factors influencing pedestrian injury severity crucial. To accurately explore factors affecting pedestrian injury severity within crashes data, a ...
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 ...
Evaluation of Factors Influencing the Compaction Characteristic of Recycled Aggregate Asphalt Mixture
Publisher: ASCE
Abstract: Aggregate and air void distribution determined by compaction commonly affects damage appearance and development inside asphalt mixture and is related to asphalt pavement durability and quality. The main objective of this ...
Quantitative Analysis of Vehicular Traffic Flow Order at Signalized Intersections
Publisher: ASCE
Abstract: A quantitative evaluation of the traffic flow order is necessary to improve the operational level at intersections. To date, how to assess the subjective perceptions of the traffic flow order at intersections is unclear. ...
Criteria for Clogging Potential in Coarse-Grained Strata during Shield Tunneling
Publisher: American Society of Civil Engineers
Abstract: Engineering practice has shown that shield machines may become clogged in coarse-grained strata. The criteria for determining the clogging potential in coarse-grained strata were proposed. With the surface area ratio of ...
Investigation of the Hydraulic Properties of Pervious Pavement Mixtures: Characterization of Darcy and Non-Darcy Flow Based on Pore Microstructures
Publisher: ASCE
Abstract: The significance of water flow behavior as one of the main properties of pervious pavements has long been recognized. However, the quantification of flow characteristics and the relationship to complex pore microstructures ...
Three-Dimensional Characterization and Evaluation of Aggregate Skeleton of Asphalt Mixture Based on Force-Chain Analysis
Publisher: ASCE
Abstract: Aggregates in contact constitute the skeleton of the asphalt mixture and affect load transmission in the mixture, which determines its deformation resistance. The objective of this study is to characterize the aggregate ...
Effects of Bitumen Origins and Filler Types on the Micromechanics Prediction of Complex Modulus of Asphalt Mastics Considering Interparticle Interactions
Publisher: ASCE
Abstract: Asphalt mastic is a binary composite in which the bitumen matrix is embedded with filler particles. By taking interparticle interactions and the effects of bitumen origins and filler types into account, this research seeks ...
Dynamic Response of Fully Permeable Pavements: Development of Pore Pressures under Different Modes of Loading
Publisher: ASCE
Abstract: Permeable pavements are widely recognized as an effective way to improve the environmental and ecological aspects of conventional dense pavements. Based on traditional pavement materials, permeable pavements are often ...
