Climate change is making extreme conditions more frequent. Severe and frequent heat, floods and rainfall could have a detrimental effect on pavement performance, which should be considered during material selection and design.
The International Road Federation (IRF) writes, “Roads are the backbone of any countries’ economy and communities’ socio-wellbeing. Sparsely populated regions around the world rely heavily on their roads for the transportation of goods and people.” But resilient and durable roads are expensive and require regular maintenance, which may not be a sustainable solution for budget-constrained countries like Africa’s Low-Income Countries (LICs).
To find a more cost-effective road pavement solution for LICs Africa, the research programme ‘Climate-resilient, sustainable road pavement surfacing’ (CRISPS) investigated the feasibility of using Modified Epoxy bitumen in Porous Asphalt (MEAC) and Chip Seals (MECS) which addresses climate-related issues with conventional bitumen in asphalt and chip seal.
The research is funded by the UK AID’s High Volume Transport Applied Research Programme (HVT) in collaboration with various institutions – the University of Birmingham (UoB), the University of Auckland (UoA), the University of Putra Malaysia (UPM), and the International Road Federation (IRF).
Research findings will be presented at the CRISPS webinar, ‘Epoxy Modified Bitumen – Performance from Laboratory Test, Trials and Applications to Date‘ on 14th December 2021.
The webinar features the following speakers:
- Dr Theuns F.P Henning, Senior Lecturer, University of Auckland. Dr Henning also leads the team at Climate Adaptation Platform.
- David Alabaster, Principal Pavements Engineer, Waka Kotahi NZ Transport Agency
