摘要: This research forms part of a larger collaborative programme conducted under the auspices OECD/ECMT (European Conference Ministers Transport) Joint Transport Research Centre, which is focused on economic evaluation long-life pavements. The aim was to investigate potential epoxy-modified asphalt as low-maintenance surfacing material. NZ Agency's (NZTA) contribution benefits open-graded porous (EMOGPA). EMOGPA appears offer for significant improvement in life surfacings. uses same mix designs conventional (OGPA), but bitumen component replaced with bituminous binder incorporating reactive epoxy resin and curing agent. Over time, this cures hard, slightly rubbery consistency. (a)
