Since 2021, we have been assisting DIR EST in Besançon with the external control of their road network. This involves 17 construction sites in 2023. 
Between April and November, our Center-East agency intervened to carry out external control of these renewal works. 
Our teamâs mission begins from the preparation phase of the construction site to its completion and includes various actions:
 Study of the Quality Assurance Plan (PAQ) provided by the contractor with the provision of technical opinions
 Technical assistance to the project manager with participation in pre-start meetings and construction meetings
 Monitoring of road planing and definition of purge zones if necessary.
 Monitoring of cleaning and reception of the base before bonding layer.
 Monitoring and control of the implementation of bonding layers.
 Control of asphalt production.
 Monitoring of asphalt implementation (temperature, compactness, macrotexture, bonding, thickness).
 Technical evaluation of any detected non-conformities.
We thank DIR Est for their trust!
