Modification of Epoxy Asphalt by Hyperbranched Polyester
Epoxy asphalt is a thermoset material used in paving industry with good properties in hot environments. However, it is still a brittle pavement in cold environments. Hyperbranched polyester (HBP), which has the characteristics of highly branched structures, massive functional end groups and low viscosity, was used as an active modifier for epoxy asphalt to improve its toughness and processability. It can be found that lower viscosity, higher tensile strength and elongation at break of HBP modified epoxy asphalt than those of epoxy asphalt can be obtained. Modulus of HBP modified epoxy asphalt higher than that of neat epoxy asphalt also indicate the improved stiffness of epoxy asphalt with the introduction of HBP.
