Innovative Concrete Barriers for Forgiving Road Infrastructure
Date Issued
2019
Abstract
One of the top ten goals set by the White Paper on
Transport is to reduce fatalities in road transport. The
European Union is aiming to halve road casualties by
2020, in line with the long term goal to move close to
zero fatalities by 2050.The most vulnerable road users
are motorcyclists, who are currently suffering from
frequent fatalities in crashes involving road barriers.
The European Road Assessment has indicated the
critical need to adopt improved barrier designs to
protect vulnerable road users. While rubberized
concrete has been recommended for road barriers,
challenges involving strength and durability of the
material have not been addressed. This research proposes to develop optimised steel
fibre-reinforced rubberised concrete mixtures as well
as road barrier designs, which will lead to the
development of SAFER road barriers with outstanding
deformability and structural integrity; thus paving the
way for forgiving road infrastructure.
The use of recycled rubber and steel wires (obtained
from End-of-life tyres) supports the Horizon 2020
Transport Research and Innovation Act priorities for
sustainability and resource efficiency (including the
Circular Economy package).
