Ballast is a granular material which is placed and packed below and around the railway sleepers. Different types of ballast materials used are broken stone, sand, gravel, moorum, brickbats etc. ... It is obtained by crushing hard stones like granite, hard trap, quartzite etc. In lieu of broken stones, limestone and sandstone can also be used.

I have to use decomposed granite for ballast because that is what is available around here. It works fine if you screen out the large pieces. I have tried titebond II and concrete. Over time nothing really is permanent. But my railroad is on the ground through the garden. So what I do now is just replace the ballast when we get some heavy rains.

Wet fouling was found to exacerbate this trend. However, coal dust had more detrimental impact on granite ballast strength when compared to limestone ballast. This could be caused by limestone's higher crushing tendency and/or possibly any differences in void structures since gradation properties of the granite and limestone samples varied.",

Degradation and fouling: High contact forces and ballast layer vibration can increase the ballast wear rate, which results in an increased volume of fines within the ballast matrix. These result in more rapid ballast settlement rate particularly in wet conditions. For high-speed railways, ballast abrasion is a common degradation type, while ballast breakage is more common for …
