Скачать или смотреть Use of Recycled Aggregates in Concrete Pavement: Pavement Design and Life Cycle Assessment

Presented By: Xijun Shi, Texas State University

Description: Pavement recycling has become a widespread practice in numerous states across the USA. Despite extensive laboratory studies on the material properties of concrete containing recycled concrete aggregate, there has been minimal focus on addressing concrete pavement design considerations and evaluating the potential sustainability advantages of this application. This study aims to fill this gap by developing pavement design recommendations that account for the changes in concrete properties resulting from the inclusion of recycled concrete aggregate. Additionally, a life cycle assessment case study has been conducted to comprehensively analyze the environmental impact of such practices. The findings of this study unequivocally support the conclusion that integrating recycled concrete aggregate into concrete pavement is not only a technically sound strategy but also holds the potential for substantial sustainability benefits.
