A cable anchorage is described for anchoring a cable, for example a stay cable comprising multiple strands (50), against a longitudinal tension force. The anchor block (11) of the anchorage comprises multiple channels, through which the strands (50) are individually threaded. Once in position and tensioned, the space around the strands (50) in the anchor block (11) is injected with a liquid, such as a polyurethane, which subsequently sets to form a tough elastic bedding material (51) within the anchor block (11). According to the invention, said elastic bedding material (51) has a durometer at 23° C. in the range 10 to 70 Shore, so as to form a bedding cushion extending substantially around the strand (50) in the strand-channel (6) along a bedding region (54) of strand-channel (6), said bedding cushion reducing the bending stresses in the strand (50) by absorbing bending stresses along said bedding region (54). |
