Dans le cadre des investissements sur 2017-2019 mobilis\u00e9s par le Sch\u00e9ma Directeur Cyclable du Sicoval, des travaux avaient \u00e9t\u00e9 engag\u00e9s afin de d\u00e9velopper la part du v\u00e9lo dans les d\u00e9placements quotidiens. Le rev\u00eatement de la piste cyclable situ\u00e9e au bord du lac de Lab\u00e8ge Innopole pr\u00e9sentait toutefois de larges fissures, atteignant localement plusieurs centim\u00e8tres. Ces fortes d\u00e9formations sont caus\u00e9es par la sensibilit\u00e9 hydrique des sols de fondation, entrainant des tassements diff\u00e9rentiels et de larges fissures de retrait. Malgr\u00e9 une r\u00e9habilitation en augmentant l’\u00e9paisseur de la structure, le ph\u00e9nom\u00e8ne r\u00e9apparaissait de fa\u00e7on r\u00e9currente et localis\u00e9e. Il fallait donc trouver une solution pour garantir la perennit\u00e9 de la piste cyclable et la s\u00e9curit\u00e9 des cyclistes.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

La g\u00e9ogrille comporte des mailles carr\u00e9es rigides et pr\u00e9sente une forte raideur permettent un interblocage de la GNT et augmentent l’angle de diffusion de la charge \u00e0 travers les couches de forme ; il en r\u00e9sulte une meilleure portance. Le g\u00e9otextile pr\u00e9vient de la remont\u00e9e de fines dans les mat\u00e9riaux nobles.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
