RUCONBAR – innovative noise protection solution made of recycled waste tyres 2

Motivation - legislation

EU Directive 2002/49/EC - assessment and management of

environmental noise

EU Transportatio Strategy White paper - European transport

policy for 2010: time to decide

The Green Paper on Noise Pollution (COM(96)540)

Landfill Directive (1999/31/EC)

Community Strategy for Waste Management (COM (96)399)

Framework Directive on Waste (91/156/EEC)

Directive 2008/98/EC legislative framework for the

handling of waste in the Community

End of Life Vehicle Directive (COM (97)358)

Waste incineration directive (2000/78/EC)

1995 White Paper on Making Waste Work

NOISE

WASTE

Large investments in road construction are planned

Noise assessed as one of the main environmental problems

All roads and railways planned for construction or

rehabilitation have to include noise protection system

From 2006 EU Directive clearly prohibits any kind of

disposal of waste tyres in environment

Obligatory to follow waste management hierarchy:

prevention,

reuse,

recycling into other forms of rubber,

recovery (converting the scrap tyres into fuel)

Quantity of waste tyres available for recycling significantly

increased

st stage (no mixtures): Preparatory research on possible application of

waste tyres in concrete included review of all available literature. Conducted

investigation showed that rubber particles have potential in fields of noise

protection barriers, creating both ecologic but also economic benefit.

nd stage (Mixtures: M0-M6): This stage was focused on

accomplishing good bond between cement matrix and

rubber as important factor for achieving higher

compressive strengths an suitable noise protection.

rd stage (Mixtures: M7-M10): After required level of

compressive strenght was achieved futher research

was directed in order to produce material with similar

properties but econmically more acceptable.

th stage (Mixtures: M11-M16): At this stage the

goal was to prepare mixtures which could

contain as much as possible waste products.

The obtained results were good, but not enough

to justify higher price of final product.

th stage (Mixtures: M17-M18): After all

conducted research it was decided to select

two optimum mixtures and use them for

production of protype in order to achieve

results which could then be consideredas

representative for the product.

Comparison with other noise barriers


Transferability and replication

RUCONBAR is widely applicable in all EU

countries that have need for:

waste tyres management,

demand for noise protection barriers

producer of both recycled rubber

granules and pre-cast concrete

elements.

Croatia has been considered as nucleus

market for RUCONBAR

Transferability and replication to the

neighbouring countries assured by

licensing of know-how and innovative

production process
