In many countries, less money is being invested in maintaining the road network, although the volume of traffic is increasing. This is why there is a growing need for cost-effective and rapid solutions to deal with dangerous sections of road. Fine milling is such a process, which is mainly used when ripples and ruts or slippery surfaces pose an acute risk to road safety.
The process is a modified form of cold milling, the only difference being that the cutting tools are spaced more closely on the milling drum. The technique is called fine milling when the line spacing decreases to 8 mm / 0.31'' or less.
The fine milling drum has a tool spacing of 6x2 mm and 672 point-attack cutting tools.
The aim is to produce a defined new surface texture. Although fine milling drums cannot repair any damage rooted deep in the road structure, they can create a level, non-skid surface
A single pass is all it takes - further steps, such as paving a new surface course, are normally not necessary.
