Minimising traffic disruption during road works on existing heavy-traffic infrastructures …

1. European Construction Technology Platform Minimising traffic disruption during road works on existing heavy-traffic infrastructures … and other impacts on users, neighbours and environment “PROPICE”, an on going passionating experience open to other transport modes

2. European Construction Technology Platform The objective • Rethink • the maintenance and rehabilitation strategies • the design and the organisation of road works to comply with the requirements of a sustainable development •  Optimise the whole • Maintenance • Operation • Users • Environmental • costs of the roads over their life cycle

3. European Construction Technology Platform The progress axis • Increase the efficiency of M&R strategies • think about sustainability at the very early stage • give priority to durable treatments • Reduce the delays supported by the users at road works sites • minimise the occupied area • shorten the interventions • optimise the traffic management • Optimise the energy consumption during works • “Greening” the sites • Reduce the noise / vibrations generated by road works by appropriate site organisation

4. European Construction Technology Platform The background • The project takes benefit from various on going or completed researches : • At European level • PAV-ECO (4th FWP) • FORMAT (5th FWP) • COST 343 action It is more concentrating on : • project level analysis • sites organisation and optimisation methods • reduction of energy consumption on sites • At national level • PROPICE (ANR – RGCU)

5. European Construction Technology Platform A all-stakeholders partnership • The present French national research project PROPICE involves : • ASF (VINCI Group), a toll motorway company • BOUYGUES construction • COLAS • LCPC, public civil engineering research centre • CSTB • EGIS Group • Scetauroute, design engineering • ISIS, operation engineering • Infraplan, consultant specialised in up stream studies

6. European Construction Technology Platform The three ECTP pillars Transformation of the construction sector A new knowledge-based construction process from concept to operation • Meeting client / user • requirement • Mobility through efficient network Stealth sites Chantiers furtifs • Becoming sustainable • Reduce energy consumption • Environmental impact • Sustainable management

7. European Construction Technology Platform Deliverables • 1) Guidelines and best practices for public and private : • Road owners • Engineering • Contractors • Road operators • 2) Key technical innovations and tools for new stealth sites • 3) High performance methods to optimise sites, from the very initial concept to construction and transfer to full operations phases • 4) Experiments and demonstrations on pilot sites
