D OUGHENING of cobbled roads by JA a German machine was demonstrated at Pateley Bridge, Yorkshire, last week. By use of an oxy-acetylene surface burner working at 3,200° C., cobbles were re-surfaced with tiny ridges. The treatment is stated to give non-skid properties lasting for five years. Further tests of the Koegel system are to be carried out by local authorities in Yorkshire.
