Bitumen is a major component used in the construction of roads in Australia and New Zealand. As it can only be manufactured from a small number of the crude oils in the world, the future supply and cost of bitumen will be directly linked to the availability of suitable crude oil sources. As crude oil is a finite, non-renewable resource there will be a point where bitumen supply will be limited, or its cost will be prohibitively expensive in terms of road construction. This report discusses several alternatives and extenders to bitumen.
