Load deformation behavior of used tires foundation with varied Filler Gradation

Abstract

Abstract In this study, waste tire is used as foundation material. Load deformation behavior was examined with varied aggregate filler gradation. The types of gradation used are: (a) 1”<(15%)<1,5”,¾”<(25%)<1”,¾<(60%)<no.4;(b)¾”<(50%)<1”, no.4<(50%)<3/4”; (c) ¾”<(100%)<1”, and (d) natural gravel 1”<(34,66%)<1,5”, ¾”<(65,34%)<1”, gradation as found in BiliBili river. Tires waste used in this study was R.16 which had been modified. Before conducting field tests, abrasion and specific gravity values of each aggregate were obtained. With applying load of20 kN, the vertical center deformationof gradation(a) was 6 mm, gradation(b) was 6mm, gradation(c) was 9 mm, and gradation (d) was 3 mm. While horizontal side deformationgradation(a) was 19,3 mm, gradation(b) was 48 mm, gradation(c) was18,8 mm, and gradation (d) was 19,2 mm.
