SLIPFORM PAVER PLACES HIGH-SPEED RAILBED

A specially designed paving train developed by the British Rail Research Dept substitutes a method for laying continuously reinforced concrete as a stable foundation for tracks carrying high-speed trains. A specially adapted CPP-60 slipform paver has five sensors to operate microswitches that control the complex cross-sectional shape of the track. A feeler arm graveling along the guide wire controls line and grade to within+/- 1/8 in. Paver can handle extra-stiff mix.
