Experimental Study on Structural Performance of Prefabricated Precast Floating Track

Abstract

To reduce railway vibration, prefabricated precast floating track along with an isolator for reducing vibration and noise was recently developed in Korea by removing existing gravel tracks within the required time without disturbing railway operations for station on the track, station below the track, and underground station sections. This study verifies the structural performance of the prefabricated precast floating track. To this end, three precast slab track panels with friction-type vibration isolators were fastened with rails for static and dynamic tests, and fatigue tests were conducted on one panel. The test results indicated that the rails and panels of the three-panel assembly test specimens satisfied the required performance. The floating track is considered to have sufficient structural safety.
