Forensic investigation of pavement premature failure due to soil sulfate-induced heave / Zhiming Si in Journal of geotechnical and geoenvironmental engineering, Vol. 134 n°8 (Août 2008) 

Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 134 n°8 (Août 2008) . - pp. 1201–1204 Titre : Forensic investigation of pavement premature failure due to soil sulfate-induced heave Type de document : texte imprimé Auteurs : Zhiming Si, Auteur Année de publication : 2008 Article en page(s) : pp. 1201–1204 Note générale : Geotechnical and geoenvironmental engineering Langues : Anglais (eng) Mots-clés : Heaving  Moisture  Compressive  strength  Soil  stabilization  Forensic  engineering  Failures Résumé : Current practice does not recommend stabilizing high sulfate-bearing soils using calcium-based stabilizers due to high potential swell and low retained unconfined compressive strength. In this technical note, a series of tests has demonstrated that a combination of lime and fly ash (Class F) proved to be the most suitable stabilizer for a high sulfate-bearing soil, and a combination of lime and slag seemed to be the most effective stabilizer for a moderate sulfate-bearing soil in terms of retained unconfined compressive strength and three-dimensional free swell potential.
