TL;DR: In this article, the authors present the results from laboratory-model tests on a strip footing supported by a sand bed reinforced with a geocell mattress and show that failure was not observed even at a settlement equal to 50% of the footing width and a load as high as 8 times the ultimate bearing capacity of the unreinforced sand.

TL;DR: In this article, the effectiveness of geocell reinforcement placed in the granular fill overlying soft clay beds has been studied by small-scale model tests in the laboratory, where the influence of width and height of the geocell mattress as well as that of a planar geogrid layer at the base of the mattress on the overall performance of the system has been systematically studied through a series of tests.

TL;DR: In this paper, the influence of lime stabilization on these soils was evaluated through determination of geotechnical properties such as liquid limit, plastic limit, swell, compressive strength, mineralogy, and microstructure.

TL;DR: In this article, the potential benefits of providing geocell reinforced sand mattress over clay subgrade with void have been investigated through a series of laboratory scale model tests, and the results indicate that substantial improvement in performance can be obtained with the provision of geocell mattress, of adequate size, over the clay sub grade with void.

TL;DR: In this paper, experimental and numerical investigations have been carried out to develop an understanding of the performance of shock mats in the attenuation of dynamic impact loads and subsequent mitigation of ballast degradation.
