RISMultiscale Numerical Modeling of Steel Bridge Deck Pavements Considering Vehicle–Pavement Interaction
Publisher: American Society of Civil Engineers
Abstract: Cracking is a major distress in steel bridge deck pavements. To determine the critical cracking zone, a numerical multiscale structural analysis was proposed and performed on the basis of a case study. First, a whole bridge ...
Investigation on Interlayer Behaviors of a Double-Layered Heterogeneous Asphalt Pavement Structure for Steel Bridge Deck
Publisher: ASCE
Abstract: The EAC+SMA composite structure, made from epoxy asphalt concrete (EAC) with stone matrix asphalt (SMA) concrete on top, is a double-layered heterogeneous structure applied to steel bridge deck pavement (SBDP) in recent ...
Rutting Prediction Model for Semirigid Base Asphalt Pavement Based on Hamburg Wheel Tracking Test
Publisher: ASCE
Abstract: Rutting is the main distress of the semirigid base asphalt pavement (SBAP). The rutting prediction model embedded in the Chinese specification was based on the rutting test results of laboratory specimens that show an ...
Effect of Curing Reaction Behaviors of Warm Mix Epoxy Asphalt Concrete on Its Field Compaction Characteristics Using Discrete-Element Method
Publisher: ASCE
Abstract: The irreversible curing reaction of thermosetting epoxy asphalt mixture (EAM) brings challenges to the construction of epoxy asphalt concrete (EAC) on the steel bridge deck, and the curing reaction degree (CRD) of EAM ...
Evaluation of Properties and Performance Improvement Mechanism of Novel Waterborne Epoxy Modified Asphalt Emulsion with Styrene–Butadiene–Chloroprene Rubber
Publisher: ASCE
Abstract: This study aims to investigate the properties of novel waterborne epoxy modified asphalt emulsion with styrene–butadiene–chloroprene rubber (SBR/CR) and evaluate its performance improvement mechanism. To achieve this ...
Vibration Reduction of Phononic-Like Crystal Metaconcrete Track Bed for Underground Railway
Publisher: ASCE
Abstract: Train vibrations can travel through the track, tunnel structure, and surrounding strata as well as into the structure of buildings near tunnels, where they can be radiated as low-frequency vibration waves and noises inside ...
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 ...
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 ...
Effect of Aggregate Gradation and Morphology on Porous Asphalt Mixture Performance
Publisher: ASCE
Abstract: Previous studies have reported the effects of aggregate gradation and angularity on the pavement performance of hot asphalt mixtures, while little work has been done on the role of aggregate gradation and morphology related ...
