Study type: Project report
One or several simultaneous changes in climate conditions, such as hotter seasons, extreme precipitation events, increasing severe storms and/or sea level rise, could severely affect roads in low-income countries (LICs). Failing to account for such impacts in future road design, maintenance and operating planning and protocols could result in accelerated road deterioration and increased risk of damage, traffic disruption and accidents, with knock-on effects on economies.
The aim of the Climate Resilient Sustainable Road Pavement Surfacing (CRISPS) project was to assess the engineering and economic suitability of three global best practice types of road surfacing technologies for use in LICs to counter the impacts of climate change. These technologies are modified epoxy chip seals (MECS), modified epoxy asphalt surfaces (MEAS) and Fibre mastic asphalt (FMA).
