Abstract

The chapter delves into the challenges posed by ballast deterioration in railway tracks and the potential of artificial inclusions such as rubber mats and geogrid to mitigate these issues. It describes the methodology of large-scale direct shear tests conducted on ballast with various configurations of artificial inclusions under different normal loads. The results reveal that these inclusions significantly influence the shear and dilation behavior of ballast, with combinations of rubber mats and geogrid demonstrating enhanced performance. The study also highlights the impact on ballast breakage, showing that the inclusion of rubber mats reduces breakage, particularly when combined with geogrid. The findings offer valuable insights into the practical applications of artificial inclusions in improving the durability and performance of railway ballast.
