In the process of manual tamping, the insertion tamping stage is the key operation to achieve the success of tamping. Under the action of inserting and tamping, the average speed of ballast fluctuates from static state to 11.8 mm/s. The ballast in the crib squeezes and fills the instantaneous gap at the sleeper underneath.

Repetitive or cyclic rail loading deteriorates the engineering properties of the railway ballast by particle crushing and rearrangement. Most of the classical elasto-plastic models are unable to predict such ballast degradation despite successfully predicting the overall load–deformation behavior during cyclic densification. In this context, the present …

It appears that a large oedometer test on 37.5mm-50mm ballast, or specification ballast, together with single particle crushing data, is the best way of …

* Vibrating screens: separate the crushed ballast into different size fractions according to the desired specifications. * Belt conveyors: transport the crushed ballast between the crushers and the screens. 5. Optional Equipment: * Sand washing machine: cleaner and finer particles from the crushing process, improving the quality of the ballast.
