Effect of styrene-butadiene-styrene copolymer on the aging resistance of asphalt: An atomistic understanding from reactive molecular dynamics simulations

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 5,   Pages 1261-1276 doi: 10.1007/s11709-021-0761-5

Abstract: To reveal the potential influence of styrene-butadiene-styrene (SBS) polymer modification on the anti-agingThe results illustrate that the SBS asphalt is more susceptible to oxidative aging than the base asphaltunder oxygen-deficient conditions due to the presence of unsaturated C=C bonds in the SBS polymer.In the case of sufficient oxygen, the SBS polymer inhibits the oxidation of asphalt by restraining theIn addition, SBS polymer degrades into small blocks during aging, thus counteracting the hardening of
