Beltzung Françoise

Françoise Beltzung is a Professor and Head of the CCDR (Center for Construction and Road Research) at the School of Engineering and Management of the Canton of Vaud, affiliated with the Institute of Territorial Engineering. Her work focuses on civil engineering, road construction, and asphalt technology, with an emphasis on material durability and noise-reduction solutions in pavements.

Research Interests:

• Development of testing methods for asphalt durability (e.g., pull-off tests for raveling susceptibility).
• Photogrammetry and remote sensing applications for road surface analysis.
• Large-scale pavement rehabilitation techniques, such as surface grinding to restore acoustic performance.
• Material characterization of porous asphalt mixtures and their long-term behavior.

Key Contributions: Her studies demonstrate innovative approaches to evaluating asphalt quality and maintaining low-noise road surfaces. Notable works include:

• Validation of pull-off tests as practical, on-site methods for assessing aggregate loss in asphalt.
• Advocacy for high-precision photogrammetry (ARRPA) in road inspection, surpassing traditional laser systems.
• Development of grinding protocols to rehabilitate semi-dense asphalt (SDA) pavements, achieving noise reductions of up to -5 dBA.

Labs/Teams: Active in the CCDR, collaborating on projects involving material science, pavement engineering, and acoustic maintenance strategies.
