Towards Sustainable Utilization of Rejuvenated Bitumen: A Review with Emphasis on Secondary Aging, Aging Resistance, and Multiple Rejuvenation

Hongbin Zhu, Naisheng Guo, Yuanyuan Li, Shisong Ren et autres

To further advance the recycling of pavement waste, the secondary-aging and multiple-rejuvenation processes of bitumen are first systematically reviewed. Beginning with primary-aging mechanisms, rejuvenator classification and physicochemical properties are summarized to aid elucidation of primary rejuvenation. Secondary-aging evolution of technical and physicochemical …

Modification Mechanism of Multipolymer Granulated Modifiers and Their Effect on the Physical, Rheological, and Viscoelastic Properties of Bitumen

Yao Li, Chao Ke, Qikai Li, Ke Bi et autres

Polymer-modified bitumen is difficult to produce and often separates during storage and transport. In contrast, granular bitumen modifiers offer wide applicability, construction flexibility, and ease of transport and storage. This study involved preparing a multipolymer granulated bitumen modifier with a styrene–butadiene–styrene block …
