Asphalt milling machine gives a fine finish

High micro-milling results are said to be achievable using the new cutter from Roadtec. This product has been developed to meet the growing demand for thinner friction courses, which require proper surface preparation. Delamination of thin courses can occur when surfaces are prepared with conventional milling equipment, according to Roadtec. The firm adds that water can get trapped in the recesses of a conventionally milled surface, leading to premature pavement failure.

Fine milling finish can be achieved using the new cutting system from Roadtec
High micro-milling results are said to be achievable using the new cutter from 1252 Roadtec.

This product has been developed to meet the growing demand for thinner friction courses, which require proper surface preparation. Delamination of thin courses can occur when surfaces are prepared with conventional milling equipment, according to Roadtec. The firm adds that water can get trapped in the recesses of a conventionally milled surface, leading to premature pavement failure.

In thin overlay applications micro-milling is required for good results, so Roadtec developed this cutter, which is able to produce a fine, straight-line pattern and does not deviate with changes in travel speed or machine stops for truck changes. Tests of the surface have shown good results, while the milled surface texture is said to be safe for cars and motorcycles when opened to traffic before paving begins. Roadtec says tooth consumption is also low with its new cutter, and, on a recent job consisting of 8km of roadway (16 lane km), 25.4mm removal with a micro finish, no teeth were changed during the five-day project.

  • Cutting better with Roadtec

    Roadtec is improving its line of cold planer cutter drums to provide a better milling pattern and a longer tool and base life. The firm has reworked the drum end ring configuration for better match-cutting and to extend tool life. The impact angle of the tools on the drum has been optimise and this will lengthen the life of the consumable bit. The lacing pattern has been adjusted and this allows for a better texture on the milled surface as well as a more balanced impact when the tools strike the cutting ar

    One of the first Wirtgen W 200 Hi cold milling machines off the assembly line is now being used for road recyling work in southern Europe. The versatility of the machine due to its novel 400mm offset drum capability has proven extremely useful for the contractor in Italy. Tuscany–based Endi Asfalti is now using the large and highly productive W 200 Hi for a wide range of milling jobs that would previously have been carried out using a combination of large and small milling machines. The proven W 200 milling

    Wirtgen brothers Jürgen and Stefan discussed growth opportunities. Jürgen Wirtgen and Stefan Wirtgen are joint presidents of the Wirtgen Group and see business levels continuing to improve. Stefan said, “Generally speaking we are surprised with the growth levels, especially in the BRIC countries. It is giving us quite a big boost and is allowing us to grow. We are more than happy with 2011 so far as the order books are full and we didn’t expect this.”
