...J. Fan; R. K. Rowe Experiments are conducted to investigate leakage through circular GMB holes overlain and underlain by both tailings with various hole diameters and GMB thicknesses. Finite element analyses are performed to explore the effect of hydraulic conductivities (k) of subgrade...

...S. Chawla; J. T. Shahu; R. K. Gupta The success of a design methodology for railway track depends on its ability to keep the maximum deviator stress induced on the subgrade due to rail traffic below the threshold stress of the subgrade soil. Considering this, the present study proposes a new design...

...G. Y. Ding; J. L. Wu; J. Wang; H. T. Fu; F. Y. Liu The dynamic behaviour of a subgrade with soilbags (filled with different materials) under traffic loads was investigated through a series of laboratory experiments. Three spaced hydraulic jacks with phase-shifted excitations were used to simulate...

...Y. Zou; C.J. Leo; J.C. Small The behavior of expanded polystyrene (EPS) geofoam used as subgrade and fill material under flexible pavement was investigated by carrying out a series of tests in a model pavement testing facility. In the experimental setup, pavement test sections that consisted...
