Multiclass Network Toll Design Problem with Social and Spatial Equity Constraints
Publisher: American Society of Civil Engineers
Abstract: In congestion pricing, apart from the conventional social equity issue between poor and rich drivers who pay the same toll charge, there exists a spatial equity issue in the sense that the changes of the generalized travel ...
Viscoelastic Model of Asphalt Mixtures under Repeated Load
Publisher: American Society of Civil Engineers
Abstract: Repeated loading test has been widely used to simulate the true stress state of pavement materials under traffic loading with more accuracy. In this paper, a half-sinusoidal load with 0.1-s loading duration and 0.9-s rest ...
Morphology of Asphalt Mixture Rheological Master Curves
Publisher: American Society of Civil Engineers
Abstract: Most asphalt mixture rheology studies were limited to condition tests and condition-evaluation indices, which cannot describe the changes in mechanical properties along with changing external conditions. The full-tempera ...
Joint Optimization of Road Classification and Road Capacity for Urban Freight Transportation Networks
Publisher: ASCE
Abstract: In previous studies, almost all urban network design models/methods made attempts to optimize transportation system performance, such as minimizing road traffic congestion, by determining optimal road capacity expansion ...
Analysis of SBS Modified Asphalt for Shearing and Developing Process
Publisher: American Society of Civil Engineers
Abstract: Microscopic observation through fluorescent optical microscope and dynamic mechanical tests and normal tests were performed in the mechanical mixing process of different types of SBS and different asphalt of different ...
Numerical Analysis of the Three-Dimensional Dynamic Response of Railway Subgrade Induced by Heavy-Haul Trains Based on FEM Model
Publisher: American Society of Civil Engineers
Abstract: Research on the dynamic response of subgrades is essential for designing heavy-haul railway subgrades. Therefore, a dynamic stress field test was carried out on the Daqin Railway using a three-dimensional dynamic soil ...
