Evaluation of the excavatability with a pick of granular materials treated with hydraulic binder with the help of a punching test

, 2016
Les matériaux granulaires traités avec un liant hydraulique présentent un intérêt certain en comblement de tranchées, et notamment pour éviter les problèmes de post-compactage. Dans un grand nombre de cas, ces matériaux doivent toutefois rester faciles à excaver à la pioche, pour que les gestionnaires puissent intervenir sur leurs réseaux, rapidement ...
