“…For examples, carbon black could block the UV rays and alleviate UV aging of bitumen, but the addition of carbon black has negative effect on low-temperature performance of bitumen [16,17]. Some UV absorbers can improve the UV aging performance of bitumen, but the effects largely depend on the type of UV absorber and the nature of bitumen [18,19]. Recently, layered double hydroxides (LDHs), also known as hydrotalcite-like compounds with host-guest supramolecular structures, were also used as UV screening agent of bitumen, and the results showed that enhanced UV aging resistance of bitumen could be obtained by adding LDHs, the main reason is that the multi-layered structure of LDHs can physically reflect the UV light by the interface of metal hydroxide sheets, which can protect bitumen from destruction of high-energy UV [20][21][22].…”

“…To evaluate the aging behavior of nanosilica modified binders, FT-IR spectral bands signal centered around 1600 cm -1 to 1700 cm -1 that show carbonyl functional groups C=O formation as a result of binders exposure to oxygen under high temperatures are used (Feng et al, 2013;Mouillet et al, 2008). From Fig.…”

“…+48668870246, e-mail: pawel.mieczkowski@zut.edu.pl Największą rolę w procesie starzenia przypisuje się reakcjom chemicznym pomiędzy tlenem a składnikami asfaltu oraz promieniowaniu UV [2,4,5,7,9]. Obszar aktywności reakcji utleniania dotyczy w głównej mierze etapu wytwarzania mieszanki mineralno-asfaltowej, a dokładnie mieszania lepiszcza z kruszywem.…”
