RISPostflooding Asphalt Pavement Condition Assessment for Roadway Operation Strategy
Publisher: ASCE
Abstract: Flooding can cause severe damage to roadway infrastructure due to inundated foundation. It is important to evaluate the postflooding pavement performance and make decisions for roadway opening and operation. Many studies ...
Improved Prediction of Peak Resistance for Spudcan Penetration in Sand Layer Overlying Clay
Publisher: ASCE
Abstract: A reliable assessment of peak resistance is the key aspect of geotechnical design for spudcan installation in sand-over-clay soil profiles. The most recent failure stress–dependent method has been validated against a large ...
Surface Modification of Basalt Aggregate by Coupling Agent to Improve the Interfacial Adhesion with Asphalt Binder
Publisher: ASCE
Abstract: The surface performance of basalt aggregate shows a great influence on the interfacial adhesion between basalt aggregate and asphalt binder and further affects the moisture stability of the asphalt mixture. To improve the ...
Establishment and Updating of Nonstationary Resistance Deterioration Model of Existing Concrete Bridge Component
Publisher: ASCE
Abstract: The focus of this research is the resistance deterioration behavior of existing concrete bridge components under the influences of environmental, material, and loading factors. To derive a more accurate resistance mathematical ...
Investigation of Field Rut Depth of Asphalt Pavements Using Hamburg Wheel Tracking Test
Publisher: ASCE
Abstract: This paper characterized field rutting performance of asphalt pavement based on Hamburg wheel tracking (HWT) rut depth. The rut depths were collected from 50 field pavement sections, and cores from the same test areas were ...
Development of a Multifunction Isolator System for the Care of Medium-Sized Laboratory Animals Harboring Infectious Diseases
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The close phylogenetic relationship between humans and nonhuman primates makes nonhuman primates an irreplaceable model for the study of human infectious diseases. In this study, we describe the ...
Wear Evaluation on Slide Bearings in Expansion Joints Based on Cumulative Displacement for Long-Span Suspension Bridge under Monitored Traffic Flow
Publisher: ASCE
Abstract: Expansion joints of bridge superstructures generally suffer deterioration more severely than their main structures, and their actual service life is generally shorter than their design service life. This paper aims at ...
Field Monitoring of an Existing Cut-and-Cover Tunnel between Two Large-Scale Deep Excavations
Publisher: American Society of Civil Engineers
Abstract: The safety of operational tunnels impacted by nearby deep excavations has led to growing interest in the field of practical civil engineering. Many researchers have studied the performance of shield tunnels during adjacent ...
Mechanical Properties and Mechanisms of Polyacrylamide-Modified Granulated Blast Furnace Slag–Based Geopolymer
Publisher: American Society of Civil Engineers
Abstract: Geopolymers are an environmentally friendly cementitious materials, which have the advantages of high strength, good durability, and stability; however, geopolymers also have some limitations, such as strong brittleness ...
Load Effect, Safety Assessment, and Traffic Strategy of Multigirder Bridges under Lateral Eccentric Customized Transport Vehicle
Publisher: American Society of Civil Engineers
Abstract: Customized transport vehicles (CTVs) are usually required to travel along the bridge centerline at low speed. However, emergency situations might occur on the bridge during the passing of a CTV and result in partial closure ...
