Monitoring pavement condition during its service life is paramount in order to antici-pate and optimize the potential maintenance work. For this purpose, different non-destructive techniques (NDT) are used to evaluate the structure distresses condition and to provide necessary information for the maintenance tasks. On their own, they are limited to...
La cartographie de flux et de mouvements peut apparaître d'un point de vue sémiologique comme simple et peu variée dans la mesure où les modalités de représentation s'articulent essentiellement autour du tracé de figurés linéaires plus ou moins larges, éventuellement colorés et orientés. Toutefois, l'interprétation de ce type de carte qui peut repr...

The preservation of natural resources via the management of diffuse pollution is currently considered to be a significant challenge in France. Pollution reduction policies are notably based on the identification of vulnerable areas. In this context, our work aims to develop a method for characterizing the surface water vulnerability to phytosanitar...
In this study, we present an operational methodology for mapping irrigated areas at plot scale, which overcomes the limitation of terrain data availability, using Sentinel-1 (S1) C-band SAR (synthetic-aperture radar) and Sentinel-2 (S2) optical time series. The method was performed over a study site located near Orléans city of north-central France...

La pyrolyse-GC-MS est de plus en plus utilisée pour quantifier les microplastiques (MP) dans les matrices environnementales, même si des développements méthodologiques sont encore requis. Cette méthode donne accès à une concentration de MP en masse de polymères et peut ainsi être utilisée en complément des méthodes en spectroscopie micro-IRTF et Ra...
The paper presents some results concerning the development of a multi-sensor hybrid approach for measuring rail roughness using acoustic and vibration signals measured on-board. The main objective of the system is to provide better input data for noise mapping and maintenance strategies. Several improvements to existing systems are proposed, based ...
The determination of the thermal resistance of a building envelope is fundamental for the evaluation of the thermal performance of buildings. This could help to evaluate and verify the energy efficiency performance of constructions before renovation, during construction, upon delivery and during use. Some methods exist in the scientific literature ...
