The choice for Sustainable Development “The choice for sustainable development has been part of the very make-up of the French government since May 2007, when road issues were delegated to the Ministry of Ecology, Sustainable Development and Spatial Planning … We must satisfy the legitimate aspirations of populations concerning mobility and quality of life, without further thwarting the planet’s potential and without reaching the stage of exhausting our resources, rendering every sort of development impossible for generations to come.” Jean-Louis Borloo, Ministre d’État

Some Facts – Gore-y details Over the last 10 years, climatic catastrophes have caused 0.9 million deaths, disrupted 2.6 billion people and financial losses exceeding $210 billion Highest ever recorded average temperature in France in 2006 By 2050, 40% reduction in ice barrier, causing sea level rise that will affect 1.2 billion people and create 200 million climatic refugees Required to reduce CO 2 emissions by 20%, compared to 2002 benchmark, within 10 years

Changing road user behaviour Raising of transport costs (taxation & tolls) –Encourage users to use road space more rationally –Promote a rebalance towards less polluting modes of transport –Significantly improve alternative choices and render them attractive to users –Urban tolls found to be an effective means to reduce congestion and pollution –Accepted that raising road charges may have undesired consequences on a country’s economic and social fabric

Actions by decision makers Appropriately respond to four key challenges: the environment & climate change, congestion, access & mobility, and safety Curb transport consumption: –Promote other modes of transport & implement efficient inter-modal facilities –Use electronic toll collection systems –Information systems (ITS) to optimise the usage of existing infrastructure Additional line item in tender to assess environmental damage caused by proposed construction methods/materials (e.g. $/t CO 2 )

Adaptation of technologies Shift in focus: resistance of structures  sustainability of engineering structures Reduce CO 2 emissions and energy consumption: –Warm, half-warm & cold processes Recycling –Use up to 60% of recycled asphalt (50% on A28) with new plant at a production rate of 300t/h –Re-use of existing pavement materials –Incorporation of building rubble & industrial by-products

Technical Innovation “Green” technologies –Making use of natural raw materials that are renewable: Bio-fluxes to reduce viscosity of bitumen (by-products of renewable natural fats that polymerises with bitumen) Bio-cleaners with superior solvent power to protect/clean equipment (replace fuel oil type products) Bio-emulsifiers Bio-road markers Bio-binders Bio-fuels –“De-polluting” roads: “Active Asphalt”: surfacings which induce a negative charge and thus able to attract suspended particulate matter Photocatalystic coatings (TiO 2 ) which neutralise NO x

Reduction in Future Costs Preservation of infrastructure: – Greater focus on maintenance – Proper management of assets Long-life pavements: –Concrete solutions –High-Modulus Asphalt (HiMA)

Concluding Remarks From an industry point of view, sustainable development should not be perceived as a new series of constraints hampering our activities but rather as a broadening of our field activities and development Sustainable development rapidly becoming a new multi-billion industry with innovation being a major catalyst : “the Oil Age” – next 100 years?
