New grip for old roads.

In many road rehabilitation projects, fine milling offers an economically efficient alternative to expensive, time-consuming full rehabilitation measures. What damage patterns are suitable for rehabilitation by fine milling? What are the special characteristics of fine milling drums?

Many countries are investing less money in maintaining their road network despite increasing traffic loads. The result is a growing demand for fast and economically efficient solutions that are capable of taking the edge off hazardous stretches of road. Fine milling is such a method, and is predominantly used where bumps and wheel ruts, or slippery surfaces pose an acute danger to traffic safety.

Large numbers of tools improve the surface texture

Fine milling is a modification of the standard cold milling method, the difference being that the cutting tools on the drum are arranged at much narrower intervals. One speaks of fine milling when the so-called tool spacing is 8 mm or less. These special milling drums are fitted with a much larger number of cutting tools than standard milling drums.

New grip for the road

The goal of fine milling is to produce a new, precisely defined surface texture. Even though fine milling drums are not capable of eliminating damages that are located deep within the pavement structure, they can produce an even pavement surface with excellent grip.

Rehabilitation in one single pass

After installing a fine milling drum in the milling drum housing, the cold milling machine cuts grooves into the pavement at intervals of between 8 mm and 3 mm and at a maximum depth of 50 mm, producing a fine surface texture in just one machine pass. Additional work steps, such as paving a new surface layer, are usually not required.
