RISThree-Dimensional Finite-Element Modeling for Asphalt Concrete Using Visual Cross-Sectional Imaging and Indirect Element Meshing Based on Discrete-Element Models
Publisher: American Society of Civil Engineers
Abstract: Numerical simulation for asphalt concrete using the finite-element (FE) method has been widely explored during the last few decades. However, the FE model reconstructions for asphalt concrete samples are mainly limited to ...
Investigation on Temperature Effect of Bridge Bearing System during Steel Bridge Deck Pavement Paving
Publisher: ASCE
Abstract: Observed damages of bridge bearings in some engineering projects during high-temperature asphalt pavement paving has attracted more attention to the dramatic temperature effect during the paving process. In this research, ...
Characterization of Roadway Epoxy Asphalt Binder with Different Epoxy Contents
Publisher: American Society of Civil Engineers
Abstract: The increasing durability demand on pavements has led to the formulation of requirements for broader applications of epoxy asphalt in roadway pavements to achieve supreme performance. However, for decades, epoxy asphalt ...
Investigation on Fracture Performance of Lightweight Epoxy Asphalt Concrete Based on Microstructure Characteristics
Publisher: American Society of Civil Engineers
Abstract: In order to investigate the fracture performance of lightweight epoxy asphalt concrete (LEAC) used in steel bridge deck pavement, experiments and numerical simulations were used to analyze the effect of lightweight aggregate ...
Selective Removal of Heavy Metals from Industrial Wastewater Using Maghemite Nanoparticle: Performance and Mechanisms
Publisher: American Society of Civil Engineers
Abstract: This study investigated the applicability of maghemite
Temperature Behavior and Stability Analysis of Orthotropic Steel Bridge Deck during Gussasphalt Pavement Paving
Publisher: American Society of Civil Engineers
Abstract: Gussasphalt concrete (GAC) is increasingly used in long-span steel bridge deck pavements because of its impermeability and compliance. However, the paving temperature of GAC is very high, inducing a significant nonuniform ...
Centrifuge Shaking Table Tests on Precast Underground Structure–Superstructure System in Liquefiable Ground
Publisher: ASCE
Abstract: Underground structures in liquefiable ground are prone to severe earthquake damage, and the seismic responses of such underground structures can be affected by nearby superstructures. Two centrifuge shaking table tests on ...
Linking and Comparison of the Damping of Fluid Transients and Frequency Response Diagram Methods for Pipe Leak and Burst Detection and Localization
Publisher: American Society of Civil Engineers
Abstract: The purpose of this study was to illustrate the relationship between methods that utilize the damping of fluid transients and approaches based on frequency response diagrams and to discuss the two methods for both leak and ...
Adsorption of Methylene Blue and Phenol by Wood Waste Derived Activated Carbon
Publisher: American Society of Civil Engineers
Abstract: The phosphoric acid activated carbon (PAC) was derived from waste wooden pallets by a two-step chemical activation technique, carbonization and phosphoric acid activation in sequence. A widely used commercial activated ...
Pipe Burst Detection, Localization, and Quantification Using the Transient Pressure Damping Method
Publisher: ASCE
Abstract: The purpose of this paper is to present a technique for burst detection, localization, and cross-sectional area quantification based on the damping of fluid transients. The Fourier components of the transient signal are ...
