Evaluating the effects of polyphosphoric acid (ppa) on the anti-ultraviolet aging properties of sbr-modified asphalt

HIGHLIGHTS

  • who: Yanling Xu et al. from the School of Civil Engineering, Chongqing Jiaotong University, Chongqing, China have published the research: Evaluating the Effects of Polyphosphoric Acid (PPA) on the Anti-Ultraviolet Aging Properties of SBR-Modified Asphalt, in the Journal: Materials 2023, 2784 of /2023/
  • what: This studies have reported that styrene butadiene rubber-modified asphalt (SBRMA) has a good cracking resistance at low temperatures. The main reason for this is that the high-intensity UV radiation accelerates the photoaging process of asphalt materials in road applications. In this study, the molecular structure changes in . . .
