DANTAS, G. H. S. (2012). Study of the feasibility for using the Superpave Giratory Compactor in a clayey soil compaction. Master Thesis (Mastering) – Engineering School of Sao Carlos, University of Sao Paulo. This research presents the feasibility for using the Superpave Giratory Compactor (SGC) in soils compaction and a comparative evaluation between Proctor’s and SGC’s compaction processes. In order to evaluate the SGC compactor, a clayey soil was submitted SGC compaction tests at three normal stress (200, 400 and 600 kPa) and two different weight specimens (1000 and 1800 g). Mechanical tests to determinate the compression and tensile strength and resilient modulus were done on specimens compacted statically and by kneading. Additionally, it is suggested a compaction protocol test on SGC. About SGC’s result tests indicated that dry densities values (a) at 200kPa were lower than those obtained at 400 and 600 kPa; (b) at 400 and 600 kPa did not exhibit important variations (c) of 1000g specimens were higher than the 1800g ones and (d) did not increases after 75 number of gyrations. Regarding to mechanical properties, it can be detected that, in general, compression and tensile strength of SGC’s specimens were better than the specimens compacted statically ones, and, as resilient modulus, specimens compacted statically had better perform than SGC’s specimens.
