ABSTRACT
Two lots of feedback are presented here that are representative of two sites using fly ash in road and rail infrastructures; namely the construction of the new LGV line embankment, and that of a major detour road in LIOCOURT (Moselle region). This article deals with prior tests and studies, the follow up and control of works, notably in a geotechnical and environmental perspective. A concrete application for the design of pavement subbases is provided in the case of the detour road.
Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.
