Laboratory evaluation of cold recycled mixture with foamed waste oil-activated rubberized asphalt
To realize the resourceful utilization of roadway waste for recycling and low-carbon construction, two environmental-friendly pavement technologies pertaining to cold recycled foamed asphalt mixture and crumb rubber asphalt (CRA) were combined to prepare foamed rubberized asphalt cold recycled mixture (FRA-CRM). The results indicate that pre-swelled activated crumb rubber (CR) by waste oil with foaming agent can enhance the foaming effect of CRA and reduce the manufacturing temperature by 15 °C, and it presents better fatigue resistance and low-temperature performance. Moreover, the moisture susceptibility, high-temperature rutting resistance, and low-temperature cracking resistance of FRA-CRM have been substantially ameliorated in comparison with traditional foamed matrix asphalt cold recycled mixture. Life cycle assessment analysis shows that compared with conventional hot mix CRA mixture, the production demand of FRA-CRM per 1 t contributes to approximate 45.13 % reduction in greenhouse gas emissions and 51.38 % of energy saving.
期刊介绍：
Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution.
We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
