ABSTRACT:
A railroad track has a roadbed made of concrete and a pair of track beams of precast concrete mounted to the roadbed. Main bodies of the track beams have at the tops thereof a plurality of protrusions serving as ties and a plurality of recesses for receiving adjusting ties. The protrusions and the recesses are alternately disposed in the longitudinal direction of the beams. The track beams extend continuously in parallel, and a pair of rails are laid on the track beams. A method of constructing the track includes the steps of supporting the track beams on the roadbed with screwjacks embedded in the main bodies of the track beams, and forcing concrete between the main bodies of the track beams and the roadbed to form concrete layers securing the track beams to the roadbed.
