Abstract: A method of filling a sleeve 4 of cable stay anchorage with a filling material comprising aggregate particles and a curable liquid mixture of an epoxy resin and a powder, comprising the steps of first filling the sleeve 4 with the curable liquid mixture (via pipe 10), secondly adding the aggregate particles (via pipe 11) and then allowing the liquid mixture to cure to form a solid mass containing the aggregate particles. The method of filling the anchorage is considerably easier than prior art methods, does not require the use of injection pumps and provides a filling material with low shrinkage and good corrosion and friction preventing properties. The anchorage also has plastics locating members 7, 8 to hold the wires 1 out of contact with the sleeve wall, to prevent friction under cyclic loads.
