For roads for positive change
The new technologies displayed at the festival highlighted the need and demand for a more efficient use of resources, from low emissions transport technology to new fuels. The tunnel by Shell Bitumen used the concept of a light-coloured asphalt that can be designed to lighten road surfaces without the need for sharp artificial lighting. In tunnels where this product has been used, it has been proved that a light-coloured asphalt can increase contrast to the human eye making cars and obstacles more visible, whilst also using up to 40% less energy in the form of artificial lighting.
The story of coloured asphalt, or Shell Mexphalte C as we know it now, began in 1967 with the development of the world’s first synthetic binder, Shell Colouradd, that enabled users to pave roads and other surfaces with durable colour. Over fifty years later, Shell Mexphalte C has been used in a multitude of projects and applications all over the world; from bus lanes in Australia and the UK, to cycle lanes in the Netherlands and tunnels in Switzerland.
With over 3.6 billion of the world’s population living in cities, the durability of road infrastructure has never been more important. Every week we build a new city of over 1.4 million people — this number is only set to grow as the Shell and Centre of Liveable Cities’ joint study ‘New Lenses on Future Cities’ found that at our current growth rate, the world’s population will increase to nine billion by 2050, with 6.3 billion living in cities.
