RISOxidation Macrokinetics of Sulfite in the Zinc-Based Wet Flue Gas Desulfurization Process
Publisher: ASCE
Abstract: The zinc oxide method is one of the most popular flue gas desulfurization processes, especially for the control of low-content sulfur dioxide. In this process, zinc sulfite can be oxidized to form a soluble zinc sulfate, ...
Numerical Simulation of Viscoelastic Behavior of Asphalt Mixture Using Fractional Constitutive Model
Publisher: ASCE
Abstract: An innovative procedure was proposed to simulate the viscoelastic mechanical behavior of asphalt mixture. The existing fractional viscoelastic models were quantitatively analyzed, and the fractional Zener model was adopted. ...
Evaluation of Dilatancy Behavior of Asphalt Mixtures Using Partial Triaxial Compression Tests
Publisher: American Society of Civil Engineers
Abstract: Dilatancy behavior plays a key role in the rutting of asphalt mixtures; therefore, it is important to study its behavior to better predict and mitigate rutting of asphalt pavements. In this study, a partial triaxial ...

Mechanical Property Evaluation for Steel Slag in Asphalt Mixture with Different Skeleton Structures Using Modified Marshall Mix Design Methodology
Publisher: ASCE
Abstract: Steel slag is increasingly applied during road construction and maintenance processes due to its superior surface and mechanical properties such as hardness, rough surface, and wear resistance. In this paper, the effects ...
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 ...
Permittivity Heterogeneity Influence of Multiphase Pavement Materials on Ground-Penetrating Radar Detection Results: A Study Based on Probability Distribution
Publisher: American Society of Civil Engineers
Abstract: For ground-penetrating radar (GPR) detection, multiphase heterogeneous pavement models were built and on-site detections were conducted. The statistic distribution rules of relative permittivity in pavement materials ...
Viscoelastoplastic Constitutive Model for the AC Lower Surface Layer Considering Time-Varying Characteristics during the Intelligent Compaction Process
Publisher: American Society of Civil Engineers
Abstract: Intelligent compaction (IC) technology based on the continuous compaction control (CCC) technology enables real-time monitoring, evaluation, and feedback of compaction quality. However, the lack of a viscoelastoplastic ...
