The addition of fibers to asphalt mixtures has the potential to improve the resistance of asphalt mixtures. However, the impact of different fiber types and binder grades on the performance (rutting, cracking, and fatigue) of fiber-reinforced asphalt concrete (FRAC) is unknown. This study aims to predict the pavement performance of control and FRAC [carbon, fiberglass, basalt, and polyolefin/Aramid (PFA)] mixtures for warm (New Jersey) and cold (Minnesota) climates using AASHTOWare Pavement ME software (PMED). Laboratory-measured dynamic complex modulus |E*| and data for PG76-22 and PG58-28. Prediction analysis showed that the PFA mix is 8% and 13% more effective in rutting for NJ and MN regions, respectively. Based on the critical distresses (rutting and bottom-up fatigue cracking), the structural layer coefficients are in the range of 0.44 to 0.48 for the MN region;however, for the NJ region, the range is from 0.44 to 0.60. Although FRAC mixtures are expansive, lower thickness, and performance enhancement assure their economic benefits. © 2023 Airfield and Highway Pavements 2023: Design, Construction, Condition Evaluation, and Management of Pavements - Selected Papers from the International Airfield and Highway Pavements Conference 2023.

Open-graded friction course (OGFC) mixtures are widely known for rapid water drainage, enhanced surface texture, improved driver safety, and reduced splash and spray. The objective of this study was to verify the predictive capability of Pavement ME total rut depth predictions with that of the average rut depth measurements in the field for the same OGFC sections. Mixture volumetric inputs for Pavement ME software, such as air voids, binder content, and aggregate gradation, were gathered from previously conducted studies for six different OGFC sections of Interstate 75 (I-75) south of Atlanta, Georgia. The traffic data was collected from the weigh-in-motion (WIM) stations closest to the field sections, while the climatic data was collected from the MERRA-2 weather station along the I-75 south of Atlanta, Georgia. As these values were well below the failure criteria, an additional analysis was performed for the rut depth after 20 years. Even this result was well within the specified criteria. Within the limitations of this study, Pavement ME software gave a conservative prediction for rut depth when compared to field observed values. Overall, the study highlighted benefits and challenges of using Pavement ME software for OGFC rut depth predictions. © ASCE *** rights reserved.

This paper introduces an eco-friendly approach to developing cementitious materials using reclaimed cement obtained from demolished structures or disaster debris as a partial replacement for virgin cement, with a focus on the properties of the resulting cement paste. This innovative practice aims to reduce the demand for new cement in the building and construction industry, thereby contributing to a more sustainable and carbon-neutral built environment. Specimens with varying proportions of reclaimed cement, ranging from 0 to 20%, were prepared and analyzed for both fresh and hardened properties. The findings reveal that cement paste containing up to 20% reclaimed cement shows comparable performance to control specimens made solely with ordinary Portland cement (OPC), indicating their potential suitability for various built environment applications. © 2024 IABSE Symposium Manchester 2024: Construction's Role for a World in Emergency.

With the rapid development of autonomous driving technology, it is imperative to study the impact of this technology on the resilience of urban road transportation networks. This study focuses on virtual traffic signal control (VTS) as a representative of autonomous driving technology and proposes a multi-dimensional resilience evaluation system to compare the impacts of three different signal-timing strategies on the resilience of urban traffic networks under various scenarios. Simulation results demonstrate that the average vehicle speed under VTS control is 38.1% and 40.1% higher than the other two control modes, respectively. In addition, the VTS approach significantly reduces delays and minimizes fuel consumption compared to the other two approaches. Moreover, this paper delves into the intrinsic mechanisms by which VTS enhances traffic resilience. It highlights the importance of integrating autonomous driving technology into traffic strategies to achieve carbon emissions reduction and promote sustainable transportation. The network resilience enhanced by VTS enables cities to effectively respond to unexpected events, thereby ensuring smooth traffic flow and safety. This research provides valuable insights into existing knowledge and promotes further research in the field of traffic resilience. © ASCE.
