Highlights: [•] UV radiation produces either atomic ionization or free radicals within asphalts. [•] Sara fractions change its composition due to aging process. [•] Rheological behavior depends on chemical changes in asphalts by asphaltenes growth. [•] MSCR test is a good tool to observe the behavior of deformation asphalt after aging. [•] A period after STA and before LTA produces recovery on penetration, ductility and G*. [ABSTRACT FROM AUTHOR]
