Abstract
This work presents the results of experiments carried out to investigate the potential application of the technology of railway track alignment: “stoneblowing”. In this technology, ballast stones are injected into gaps of the ballast bed beneath sleepers. Despite potential benefits, this technology has a limited application. In order to understand the performance of the ballast aligned by stoneblowing and to develop maintenance procedures, we conducted series of experiments at the Experimental Railway Ring in Shcherbinka, Russia. It was found out that the railway track, aligned by stoneblowing and flat reinforcement geogrid, showed better track stability in vertical plane in comparison to the track aligned only by stoneblowing. Finally, railway tracks aligned by stoneblowing techniques proved to show good results under high loads.
