Fatigue cracking is a common form of flexible pavement distress, which generally starts and spreads through bitumen. To address this issue, self-healing elastomer (SHE) modified bitumens were elaborated to assess whether these novel materials can overcome the neat asphalt (NA) fatigue performance and whether the current failure definition, failure criterion, and fatigue-restoration criteria can fit their performance. All bitumens were subjected to short-term and long-term aging.

Article Synopsis
- SBS-modified asphalt is commonly used in road construction, but restoring aged versions is challenging; this study explores using SBR and bio-oil as a solution.
- The research involved creating recycled asphalt with varying amounts of bio-oil and SBR, with tests demonstrating that bio-oil effectively reduces viscosity and improves asphalt durability compared to SBR alone.
- Microscopic tests revealed that SBR and bio-oil lower the stiffness and enhance the anti-cracking properties of aged asphalt, with bio-oil contributing beneficial compounds that resist oxidation.
An increasing amount of waste seashells in China has caused serious environmental pollution and resource waste. This paper aims to solve these problems by using waste seashells as modified materials to prepare high-performance modified asphalt. In this study, seashell powder (SP) and stratum corneum-exfoliated seashell powder (SCESP) were adopted to prepare 10%, 20% and 30% of seashell powder-modified asphalt (SPMA) and stratum corneum-exfoliated seashell powder-modified asphalt (SCESPMA) by the high-speed shear apparatus, respectively.
