This invention discloses a method for improving the interfacial bonding performance between the filler layer and the track slab, comprising: preparing a release cloth of the same size as the bottom plate of the track slab and capable of permeating and absorbing cement slurry on both sides; after vibrating and leveling the track slab concrete, laying the release cloth flat on the bottom of the track slab, allowing the slurry-rich layer on the surface of the track slab concrete to permeate into the release cloth, forming a dense cement slurry layer with strong adhesion; laying, fine-tuning, and sealing the bottom of the track slab with the release cloth bonded to it, and then pouring self-compacting concrete. During the pouring of the self-compacting concrete, the internal floating slurry permeates to the release cloth bonded to the bottom surface of the track slab, some of the water in the slurry is absorbed and evaporated by the release cloth, and the floating air bubbles are absorbed and broken at the release cloth, thereby increasing the density of the upper surface of the self-compacting concrete and forming a strongly bonded air bubble and water seepage slurry absorption layer with the release cloth. This invention can effectively improve the interfacial bonding performance between the filler layer and the track slab, and extend the service life of the track structure.
