RTS Ⅱ type plate without a frantic jumble ballast bed structure and main technical requirement, the structure of the subgrade section of roadbed by rail board, cement emulsified asphalt mortar filling layer, support layer and other parts. Curve is high on the surface layer of subgrade bed set. Second, the structure of the bridge section of roadbed by rail board, cement emulsified asphalt mortar filling layer, base plate, sliding, high-strength extruded board, lateral block and elastic limit board and other parts. After the abutment roadbed set anchorage structure ( Including friction plate, geotextile, side) And the transition board. Curve super-high board set on the base. Long bridge section of the base plate is equipped with steel plate connector latter pouring belt. Three section of roadbed, tunnel structure by the track plate, cement emulsified asphalt mortar filling layer, support layer and other parts. Curve super-high in inverted arch backfill layer ( There are inverted arch tunnel) Or floor ( No inverted arch tunnel) On the set. Four, cement emulsified asphalt mortar filling layer and the bottom of the track plate and supporting or base plate dense paste, thickness of 30 mm, should not be less than 20 mm, should not be greater than 40 mm. Five, the track plate except fracture in advance, other parts can not have crack. Six concrete cracks, rail between the joint shall not be greater than zero. 2 mm, cast-in-site concrete seam and seam track plate screen shall not be greater than zero. 3mm。 Seven, bridge area continuous base plate ( Afterward casting zone containing) Concrete cracks may not be greater than zero. 3 mm, lateral block and the base plate shall not adhesion. Eight, roadbed and tunnel section bearing layer can not have vertical through crack. Nine, should be kept unobstructed drainage channels.
