1. 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 European Construction Technology Platform

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

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

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

5. 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 European Construction Technology Platform A all-stakeholders partnership

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

7. Deliverables 1) Guidelines and best practices for public and private : Road owners Road owners Engineering Engineering Contractors Contractors Road operators 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 European Construction Technology Platform
