[Display omitted] •Core-shell rubbers (CSRs) with two core polymers have been used to toughen epoxy asphalt (EA).•2 wt% CSR with polybutadiene (PB) core alters the phase separation mechanism of EA.•Both swollen polymer and asphalt particles form in the continuous epoxy phase of EA.•The area fraction...
