摘要：
The invention describes a novel material intended for use in public works, constituted by a mixture of granular, alluvial or clay soils, of hydrophilic polymers and cationic hydrophobating additives, wherein this material presents a high insensitivity to variations of ambient humidity and is intended in particular for use with building roads.
