The invention relates to a method for fastening screws with a diameter between 20 and 30 mm with a coarse pitch and with an unthreaded screw shaft, especially tie screws, in a drill hole by means of an adhesive and bracing solid particles. Said bracing solid particles are synthetic particles with a particle size that is by at least 90 % twice the average distance between the screw shaft and the wall of the drill hole. The synthetic particles must fulfil a number of requirements, especially requirements for the track construction of high speed trains. |
