Abstract (en)
[origin: EP1533421A2] To process and test used concrete sleepers (1), from a railway permanent way, the quality of the concrete is tested by an acoustic ultrasonic analysis, and its elasticity is tested by bending stresses. The depression is measured where the rails lay, and the strength of the screw bolts (2) and dowels (3) anchored in the concrete is assessed by pulling (6) at a clamp (4) on them while the surrounding zones (5) are secured. The concrete sleeper is also inspected visually for any cracks, or other faults.
