Toughness modification of hyperbranched polyester on epoxy asphalt
Graphical abstract
AbstractThermosetting epoxy asphalt, which has great mechanical properties and excellent thermal stability, is one of the preferred paving materials on steel bridge deck. However, because epoxy asphalt has high modulus and brittleness in cold environments, it still has a risk of propagating non-repaired brittle crack in winter. Hyperbranched polymer (HBP) can be used as an active modifier for epoxy asphalt to improve its toughness. It can be found that viscosities of HBP modified epoxy asphalts are slightly increased during curing process, but the percent elongation of epoxy asphalt could be effectively improved by HBP with enough tensile strength.
