By means of milling off, the evenness of the surface was improved and the safety of traffic increased. Aquaplaning, particularly on the nearside lane, led to accidents; a 2 to 4 cm depth of milling obviated the aquaplaning. The concrete withstood the effects of milling off without deterioration. Joint damage was tolerable.

Cm (capability machine) The Cm index describes machine capability; it is the number of times the spread of the machine fits into the tolerance width. The higher the value of Cm, the better the machine. Example: if Cm = 2.5, the spread fits 2½ times into the tolerance width, while Cm = 1 means that the spread is equal to the tolerance width.
