5.7 Eco-road building for emerging economies

The construction and maintenance of road surfaces and pavements requires sealers and binders which are currently based on highenergy, environmentally damaging fossil fuels (bitumen and asphalt) or cement. Furthermore, developing countries find that importing and transporting these products is costly and that the heavy loads damage domestic road infrastructure.

A 'technology scouting' methodology identified promising alternative technologies that could develop sustainable, low-carbon footprint solutions using local resources and initiate local employment in developing countries. These could arise from local agricultural and manufacturing operations, and waste streams from industrial activities and power generation.

Six potential technology areas recommended for further examination are:

These technologies could contribute to achieving provision of affordable and sustainable universal access across the developing world.
