What is it about?
We suggest a new test method to determine dynamic lateral resistance of sleeper. A pendulum loading test device (PLTD) is developed and assembled at laboratory. We subject a concrete sleeper to several impact loads utilising this apparatus in lab. The results are mainly functions of impact load, and compared with static outputs.

Why is it important?
This research opens a new window to the world of soil dynamics and track lateral resistance. Since the advent of high-speed trains, quasi-static analyses have been unable to predict the interaction between trains and tracks correctly. We have shown in this research that, contrary to their unique static lateral resistance, the dynamic lateral resistance of sleepers varies by load characteristics, and significantly diminishes in high-magnitude lateral impact loads. Therefore, we suggest others to use our methodologies instead of static ones.
Perspectives
This paper is my bachelors thesis. It literally took a toll on me - there were tons of hard-work, frustrations and all-nighters! It took us forever to publish it as a new idea, but finally we did it. I cannot express enough gratitude to those who helped me conclude my work. This research is the base of all other works I (will) have done in the field of dynamic lateral performance of ballasted tracks, and I do hope that it will be useful for others as well.
