From the aspects of survey control，roughly laying and fine readjustment of track slabs, and grouting with CA
mortar，etc.，the paper expounds the technical points of precision laying of CRTS II track slabs for ballastless track structure.
With the implementation of the techniques，the good structural continuity, smoothness，stability and durability of CRTS II high
speed track slabs were achieved，which can provide references for track construction for high speed railways.
