Recycling

Improved infrared asphalt repair technology is speeding pothole repairs in applications in North America.

Road machinery specialist BOMAG has carried out a two day demonstration event at its headquarters in Boppard, Germany.

A pavement recycling contractor in eastern New York State in the US is using an innovative and versatile Wirtgen machine to carry out very different road rehabilitation tasks. This unit is being used to lay foamed bitumen-recycling pavements as well as carrying out cold-milling.

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

Roadtec is offering a new cold recycling machine, the RT-500, aimed at duties in projects using the recycling train concept. Electrically powered by a Cat C9 generator set, the RT-500 can handle up to 600 tonnes/hour of material and is designed to crush and screen the recycled asphalt pavement (RAP) produced by an RX-900 cold planer. It has a JCI double deck screen that sorts milled material provided by the RX-900's conveyor. Any oversized material is fed back into the RT-500's Telsmith 3048 impact crusher

Efficient crushing and screening processes help produce quality products, Mike Woof reports. Having an efficient crushing and screening operation is crucial to the cost-effectiveness of a quarry as well as providing the best quality product. The crushing circuit is a key component in any quarry with the right selection of equipment as well as effective maintenance important factors in optimising performance.

BOMAG has carried out a successful series of demonstrations of its new BM500/15 compact milling machines in Berlin. The machine was tested at the Representative Offices of Rheinland-Palatinate to the Federal Government and the European Union in Berlin and for the first time the planer carried out practical tests in the grounds of the company's Berlin Branch. A total of around 100 guests watched a highly convincing demonstration. After a reception at the Representative Offices of Rheinland-Palatinate delegat
