This well-used urban towpath was upgraded some years ago. Unfortunately the attractive Bredon gravel (or similar) surface was rolled flat, so it has developed wear in the centre, showing after rain as a regularly spaced series of puddles (what's the maths behind that?). Self-setting gravel or fine hoggin should be rolled to a camber or to a cross-fall so that surface water is quickly shed.
