Titre : Suction-controlled laboratory test on resilient modulus of unsaturated compacted subgrade soils Type de document : texte imprimé Auteurs : Shu-Rong Yang, Auteur ; Horn-Da Lin, Auteur ; Kung, Johnson H. S., Auteur Année de publication : 2008 Article en page(s) : pp. 1375–1384 Note générale : Geotechnical and geoenvironmental engineering Langues : Anglais (eng) Mots-clés : Subgrades Soil suction Resilient modulus Laboratory tests Unsaturated soils compaction Résumé : Conventionally, the resilient modulus test is conducted in the laboratory under different moisture content in which matric suction is unknown during the test. To investigate the influence of the matric suction on the resilient modulus, this study integrated the suction-controlled testing system and developed a modified testing procedure for the resilient modulus test of unsaturated subgrade soils. Based on the axis-translation technique, two cohesive soils were tested to investigate the effect of matric suction on resilient modulus. In the modified testing procedure, in order to fulfill the equilibrium in matric suction, the number of load cycles at each loading sequence of the resilient modulus test (AASHTO T 292-91) needs to be increased significantly. Experimental data indicate that matric suctions measured in the specimen after consolidation and resilient modulus tests are consistent with the matric suctions deduced from the soil-water characteristic curve corresponding to the same moisture content. In general, the resilient modulus obtained by the suction-controlled resilient modulus test appears to be reasonable. The trends of resilient modulus obtained by the suction-controlled resilient modulus test are consistent with those obtained by the conventional resilient modulus test. However, the suction-controlled resilient modulus test provides better insights that can help in interpreting the test results.
