| 摘要： | Using epoxy bitumen in chip seals could significantly increase the life of high-volume roads in low-income countries and make them more resilient to climate change impacts. The technology, which has been developed and used in New Zealand, will be trialled in Ethiopia this year. Modified epoxy chip seal is one of three technologies under investigation in the 18-month Climate Resilient Sustainable Road Pavement Surfacing (CRISPS) programme; the others are modified epoxy asphalt surfaces and fibre mastic asphalt. The programme is being led by the University of Birmingham in the UK, in collaboration with the University of Auckland, the Universiti Putra Malaysia (UPM) and the International Road Federation (IRF). New Zealand and the Netherlands have been interested in using epoxy bitumen since the early 2000s, when they worked on a research programme together, explained David Alabaster, principal pavement engineer at New Zealand transport agency Waka Kotahi, at a seminar in December 2021, hosted by the IRF. Engineers observed that the material had been installed on bridge decks and was still intact 40 years later. |
