Acoustical Classification and Conformity Checking
of Road Surfaces
The European Road Federation Point of View
Stakeholder workshop on 1 August 2006 Mr. Antonio
Hidalgo, Mr. Brendan Halleman Brussels
2

• The European Union Road Federation (ERF) is
• the Brussels Programme Centre of the
  International Road Federation. ERF acts as a
  European platform for dialogue, condenses the
  road sector's input on mobility issues and
  promotes research leading to a more sustainable
  road transport.

• Priority areas
• The socio-economic benefits of roads to society,
  
• Engineering Safer Roads ,
• The environmental challenge ,
• Building financing our road network.
• Intelligent roads

• Foundation in Transport and Energy Research
  Development (CIDAUT) is
• a non-profit corporation with the objective of
  actively contributing to the needs of companies
  in the Transport and Energy sector, thus
  enhancing both their competitiveness and
  industrial development.

• Priority areas
• Road Car Safety,
• Energy and Environment ,
• Materials Products process,
• Acoustic Vibration.

• ERF Environment Position Papers
• Road Traffic Noise - The ERF Perspective
• ERF Position Paper on Road Transport and Energy
  Saving
• ERF Position on Road-related Exhaust Emissions

The Europes road sector have a problem
NOISE

• Who? Lots actors involves the acoustic road
  scheme
• State administration, local administration,
  regional administration
• Noise consultants
• Road constructors
• Engineering offices

• The frame Environmental Noise Directive
  (2002/49/EC)
• Noise maps to assess environmental noise covering
  all major roads (by 2007)
• Information on noise exposure and its effects
  made available to the public
• Action plans to reduce noise where necessary (by
  2008)

At now Strategic Noise Maps

• In Spain
• 5.000 km State Roads
• 1.000 km Private highways
• 2.600 km Regional Roads

Strategic Noise Maps

• In Spain
• 20 consultant works
• 18.000 Noise Maps
• Huge Data
• Expectation
• Millions affected people

COMMISSION RECOMMENDATION. (August 2003)
concerning the guidelines on the revised interim
computation methods for industrial noise,
aircraft noise, road traffic noise and railway
noise, and related emission data. (C(2003) 2807))

• And them Action Plans
• Road Acoustic Solutions
• Traffic Management Strategies
• Acoustic barriers (NRD)
• Road Surfaces
• Acoustic isolation affected façades

10

• Action Plans
• Actors need talk in the same idiom about
• Quantify the acoustic benefit of the solutions
• Quantify the cost
• How many gain decibels?
• How much less people affected?
• Cost/benefit?

11

• Action Plans
• Needed guidelines standard in order to
• Choose the best solution in the action plan
  project
• Choose the appropriate product available in the
  market (CE marking)
• Apply and check the installed solutions
• Maintenance and long performance behaviour

12

• One example
• Noise Acoustic Devices (CEN TC 226 WG6)
• Recently approved EN 14388 Road traffic noise
  reducing devices. Specifications.
• Currently promoting a research project in order
  to
• establish guidelines to optimal NRD design and
  installation by improving the State of the Art
  through real life data consolidation, round robin
  tests and a collaborative research programme
  involving acousticians, test houses and
  manufacturers

ADRIENNE 2 Simplified project methodology
WP 2 Improvement of the methods for Absorption,
Insulation, Diffraction
WP 3 Relationship Lab test / in-situ test
WP 1 Coordination
WP 6 Dissemination
WP 4 Relationship near-field / far field
WP 5 Guidelines to NRD optimization
36 months
Guidelines to improve EN1793
Guidelines to NRD optimisation
Final workshop for stakeholders
14

• Asphalt Acoustic improvement efforts
• The Road Constructors and local administrations
  are doing many research projects in order to
  evaluate and improve the road noise in new
  applications. For instance, in Spain it has been
  made with the collaboration of Cidaut.
• Statistical Pass By method (SPB)
• Close Proximity method (CPX)
• Sound absorption properties in situ of road
  surfaces
• Combine effect NRD Road Surface

15

• Conclusions
• The problem of Road Noise involves a lots
  different actors
• The action plans could be a very difficult
  problem
• They need some Guidelines Standards to do the
  action plans
• This Standard is being made and improve about the
  Noise Reduction Devices by the CEN TC 226 WG 6
  (ADRIENNE 2)
• The same effort should be made in the road
  surfaces Standards
