Unballasted track construction

The invention discloses a non-ballast track structure, which aims to effectively strengthen the integrity and the anti-vibration performance of a non-ballast track and reduce the maintenance and repair workload of a track structure. The non-ballast track structure comprises a track plate (10) adopting a prestressed reinforced concrete structure, a base (30) adopting a reinforced concrete structure, and a mortar adjustment layer positioned between the track plate (10) and the base (30), wherein the mortar adjustment layer is a resin mortar layer (20), and the resin mortar layer (20) is adhered to the track plate (10) and the base (30) to form an integral structure. The non-ballast track structure has the advantages that the resin mortar layer has good elasticity and adhesive property and can firmly connect the track plate and the base into a whole, thereby improving the integrity and the anti-vibration performance of the non-ballast track structure; and the non-ballast track structure can effectively accelerate the pouring rate of the mortar adjustment layer and ensure the construction quality, so the non-ballast track structure has the characteristic of convenient site construction and can realize rapid maintenance.
