Rheological properties of eco-friendly high-modulus asphalt considering aging characteristics

This study investigates the development and characterization of Eco-friendly High-modulus Asphalt (EHA) designed to optimize technical performance, environmental sustainability, and economic viability. By incorporating PR high-modulus modifiers alongside crumb rubber (CR) and des...

An ESG-Based Assessment Framework for Project Governance in Expressway Construction Projects

Against the backdrop of the global pursuit of sustainable development, the traditional governance model for expressway projects, which prioritizes economic returns, can no longer meet contemporary sustainability requirements. Drawing on stakeholder theory and sustainable developm...

The Influence Path of Project Manager Competency on the Performance of Area Development Projects

The competence of a project manager is pivotal in influencing the success of construction projects and significantly affecting project performance. To explore the influence mechanism of project manager competency on the performance of area development projects, this study adopted...

Recognizing Mechanical Behaviors of Silt-Based Foamed Concretes from Image of Pores Using Deep-Learning Strategy

Abstract The pore structure of foamed concrete exhibits an inherent interaction with mechanical behavior. This study developed a novel deep-learning (DL) strategy to predict mechanical behavior of foamed concrete based on the image of pore distribution. This framework includes tw...
