Hydrophobic modification of an expansive soil using polymers and organic compounds: a comparative study with lime Available to Purchase

Expansive soils represent an important scientific, technical and social problem, mainly because of the cost of damage to houses, buildings, pavements and infrastructure (Bowles, 1978; Rico-Rodríguez & del Castillo, 1982; Zepeda et al., 1985; Hernández-Espino, 1988; Rodríguez, 1989; Juárez-Badillo & Rico-Rodríguez, 2000). Several additives have been used for many years to stabilise soils against expansion or contraction, lime being the most commonly used, essentially because of its low cost (Rico-Rodríguez & del Castillo, 1982; Rodríguez, 1989). However, in the last few years the use of organic compounds has come to...
