Abstract
In railway systems, tracks are installed to allow safer operation and distribute passed load on rail. Concrete slab tracks are being more utilized as railroad cars are developed to have higher speed performances when compared to Ballasted tracks. However, there are some disadvantages when it comes to noise reduction when compared to Ballasted tracks. In order to reduce those disadvantages, Concrete slab tracks have been continuously conducted in order to reduce noise and vibration but are still currently insufficient for commercialization. In this paper, Pervious concrete applying at the vehicle road field for reducing noise will be introduced and evaluated that can be applied into concrete slab track in railway field. Furthermore, the application of polypropylene polymer(PP) reinforced Pervious concrete slab track, its intensity of the absorption, and its feasibility of application has been researched.
