Vegetable oil could replace bitumen based
roads in future lowering the road building industries carbon
- 22nd July 2009
Chip fat could be used in the road building process of the
future, and help cut carbon emissions at the same time.
Helen Bailey, studying for a PhD in civil engineering materials
at The University of East London,
who is being supported by
Aggregate Industries, has devised a process which replaces
the bitumen, which is used bind the asphalt together, with used
Express Asphalt testing centre in Newark is currently
running trials on the new road surface which is awaiting patent.
Providing the vegetable oil based roads still provide adequate
grip for vehicles and will not increase the risk of
car accidents for
motorists or increase the risk of
with vehicles losing control more easily on the new type of road
surface, then it should be encouraged and invested in as the
future for road building in the UK.
Once the patent has come through it will have further tests on
road surfacing projects in Lincolnshire.
If the trials do prove 100% successful and the new road surface
is used across the UK, the road building industries carbon
footprint would be massively reduced, and the reduction or
seizure of the expensive import of crude oil based bitumen would
save the UK economy millions.
