Best-fit models to estimate modified proctor properties of compacted soil / Lucio Di Matteo in Journal of geotechnical and geoenvironmental engineering, Vol. 135 N° 7 (Juillet 2009) 

Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 135 N° 7 (Juillet 2009) . - pp. 992–996 Titre : Best-fit models to estimate modified proctor properties of compacted soil Type de document : texte imprimé Auteurs : Lucio Di Matteo, Auteur ; Federica Bigotti, Auteur ; Remo Ricco, Auteur Année de publication : 2009 Article en page(s) : pp. 992–996 Note générale : Geotechnical and geoenvironmental engineering Langues : Anglais (eng) Mots-clés : Soil  properties  Mechanic  properties  Soil  compaction  Geostatistics Résumé : Regression models were developed to estimate the optimum moisture content and maximum dry density of clayey and fine-grained soils using physical and index properties from 30 soil samples collected in Central Italy and 41 soils described in the literature. The liquid limit of the soils analyzed ranged between 18 and 82%, the plasticity index between 1 and 51%, and specific gravity between 2.47 and 3.09. The most significant regression variables were the specific gravity and the Atterberg limits. The developed models are accurate and can be used as a simple tool to approximate the maximum dry density and optimum water content of clayey and fine-grained soils.

Compressibility of kaolinitic clay contaminated by ethanol-gasoline blends / Lucio Di Matteo in Journal of geotechnical and geoenvironmental engineering, Vol. 137 N° 9 (Septembre 2011) 

Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 137 N° 9 (Septembre 2011) . - pp. 846-849 Titre : Compressibility of kaolinitic clay contaminated by ethanol-gasoline blends Type de document : texte imprimé Auteurs : Lucio Di Matteo, Auteur ; Federica Bigotti, Auteur ; Remo Ricco, Auteur Année de publication : 2012 Article en page(s) : pp. 846-849 Note générale : Géotechnique Langues : Anglais (eng) Mots-clés : Ethanol-gasoline  blends  Soil  contamination  Compression  index  Kaolinitic  clay Index. décimale : 624.1 Infrastructures.Ouvrages en terre. Fondations. Tunnels Résumé : In this work, oedometer tests were used to examine the effects of ethanol-gasoline blends on the consolidation characteristics of a kaolinitic soil from northwestern Spain. As the fraction of ethanol in blends increases, the equivalent liquid limit of soil decreases, showing a dividing point for blends containing about 85% of ethanol. By means of a database of compression indexes of remolded clayey soils mixed with differing kinds of alcohol and petroleum hydrocarbon contaminants, a multivariable model for estimating the compression index of the contaminated soil is presented, on the basis of the virgin compression index, normalized liquid limit, and normalized pore fluid viscosity. The model is valid only for percentages of active clays up to 10–15% in weight in kaolinitic soil. The authors would like to encourage others to further validate and refine the approach, which may be useful for preliminary estimation of the compression index of contaminated soils, reducing operators’ risk of inhaling vapors released by the ethanol-gasoline blends while performing the test and also reducing damage to conventional oedometer equipment.
