...Hernán Patiño; Eliana Martínez; Rubén Galindo This research is based on the results of 120 determinations of the shear modulus ( G ) of a saturated granular medium (20-40 Ottawa sand) for different conditions of relative density ( D r ), effective consolidation pressure ( σ’ c ), and level...

... and cyclic testing under constant load or constant volume conditions. Validation testing using Ottawa sand C109 confirmed that the monotonic and cyclic constant volume response of the sand using the large-diameter device was similar to the results presented using conventional-sized DSS test devices...

... are used to prepare very loose saturated Ottawa sand specimens. Special equipment and techniques used for each method are described. The advantages and disadvantages of both methods and the effectiveness of the efforts to minimize disturbance due to volume changes during freezing are discussed. Properties...

... percentages of granulated tire rubber and Ottawa sand at several different percentages. The maximum shear modulus and minimum damping ratio are presented with the percentage of granulated rubber. It is shown that reference strain can be used to normalize the shear modulus into a less scattered band...

... embankments over weak or compressible soils. This paper presents the engineering properties of shredded tires, Ottawa sand, and a mixture of 50% Ottawa sand and 50% shredded tires by volume (70% Ottawa sand and 30% shredded tires by weight). The maximum size of the tire chips used was 4.75 mm. Gradation...

...VK Khosla; RD Singh A simple change in the conventional cyclic triaxial cell was made to carry out constant mean stress tests on dry Ottawa sand. Test results show that stress-strain characteristics under cyclic loading conditions are significantly affected by the imposed stress path. References...
