Abstract

Crumb rubber modified asphalt (CRMA) has emerged as a resultful solution to mitigate the environmental pollution caused by discarded tires. Devulcanized rubberized asphalt (DRA) is a better choice for CRMAs, and composite DRA can improve the impaired high-temperature performance of DRA. However, the researches on composite DRA are limited, and its emission characteristics have yet been quantitatively evaluated. To fill this gap, the emission characteristics and performance of chemically activated rubberized asphalt (CARA) and styrene–butadiene–styrene (SBS)/CARA (SCARA) were evaluated. The results indicate that SCARA achieving the best overall performance. Additionally, CARA and SCARA produce fewer harmful emissions than traditional asphalt rubber (AR), and the chemical devulcanization is more effective in reducing polycyclic aromatic hydrocarbons and benzene series emissions. SBS hybridization outperforms chemical devulcanization in reducing rubber released emissions. Thus, SCARA emerges as a highly promising materials with exceptional comprehensive performance and eco-friendly characteristics.

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.
