Challenges and Strategies in Maintaining Transport Infrastructure Assets in France
The white paper by Institute for Roads, Streets and Infrastructures for Mobility (IDRRIM) emphasizes the importance of regular maintenance and investment in the durability and performance of transport infrastructure assets in France. It discusses the impact of weather, traffic, and time scale on infrastructure quality, highlighting the need for sustained maintenance to avoid a significant increase in costs in the future. The paper also addresses the concept of "gray debt" and the consequences of delaying maintenance investment. Strategies such as the launch of studies and publications aim to raise awareness among policymakers about the critical role transport infrastructure plays in the economy.

> Roads : robustness and durability linked to the materials they are made of (stones, cement and bitumen) But But our > Functional qualities which decrease under the effects of weather and traffic > Time scale of the infrastructure vs political and economic calendar our infrastructures infrastructures and and the the services servicesthey they offer offer are are not not eternal eternal : : How How guarantee their durable quality guarantee their durable quality and performance by regular maintenance expenses, long life investment and regular maintenance expenses, long life investment and reconstruction at end of cycle ? reconstruction at end of cycle ? and performance by PPRS Paris 2015 IDRRIM, Marc TASSONE 3
Transport infrastructures : a particularly conducive field to the "gray debt" or "invisible debt" Saving on maintenance and delaying maintenance investment may look like keeping a good balanced budget But the decline in the real value of the stock decline in the real value of the stock and the effects on the of service of service will appear a few years later, requiring an investment 2 to 4 times times higher higher to bring back its utility to the infrastructure and the effects on the level level 2 to 4 To To meet these needs: meet these needs: 2012 : 2012 : launch of the study "Management and Maintenance of Urban and Road Heritage: Methods, Tools and Techniques" (GEPUR) 2014 : 2014 : Publication of the IDRRIM s White Paper to sensitize policy makers (state and local elected officials) on the need to maintain and preserve the public heritage PPRS Paris 2015 IDRRIM, Marc TASSONE 4

Value of the stock of infrastructure to GDP of different countries (depreciated value) France, with a value of 75% of GDP, ranks in the middle of countries ranging from 57% for the UK to 87% for South Africa PPRS Paris 2015 IDRRIM, Marc TASSONE 7
GDP growth and growth in the value of the stock of infrastructure: a direct link Underinvestment or lack of maintenance means: risk of impairment progressive inadequate services for which the infrastructure was designed disruption of the local or national economy risk to users Let deteriorate the intrinsic quality of the heritage returns to : depreciate gradually heritage value, since can no longer provide the expected services take the risk of not being able to repair it if its use was impossible PPRS Paris 2015 IDRRIM, Marc TASSONE 8
