Asphalt recycling and soil stabilization/substructure solidification
Significantly greater loads, due to the ever larger and faster machines and tractors, cause considerable damage to asphalted farm roads. Asphalt recycling with mounted milling machines is a sensible way of repairing dilapidated asphalt roads. The asphalt roads are recycled (milled) with the aid of cultivation milling machines and the resulting milled material is reused and installed on the spot. Binding agents e.g. (lime – cement mixtures) are worked in and compacted with the RBM milling machine to a depth of up to 40 cm, thereby creating a load-bearing substructure for a new asphalt surface course or a gravel layer as a road surface and wearing course.
For which tractors are the HEN stone milling machines and stone crushers suitable?
The stone milling machines are used for asphalt recycling, as stone crushers, stabilization milling machines and recultivation. Larger stones are crushed to a grading curve of 0-50 mm, thus creating a homogeneous and stabilizing soil structure. The milling machines for soil treatment are flexible and can be used for recycling, crushing and mixing. The treatment of asphalt pavements is possible with HEN RBM milling machines without prior ripping or pre-digging, the milling machines can penetrate directly into the asphalt surface. Water is injected directly into the soil by the HEN soil injector to produce the optimum moisture level, which plays a very important role in subsequent compaction. A new wearing course of asphalt or mineral gravel is then applied, profiled and compacted. The recycling process saves raw materials and resources, and logistics, e.g. truck transports, and thus also Co2 emissions are considerably reduced. No new mineral mixture is necessary for the construction of the road, so there are significantly fewer logistics and transport trips. The HEN mounted milling machines are available in different sizes, carrier vehicles mostly tractors from 140 to 500 HP can be used depending on the milling depth and size of the mounted milling machine.
What is asphalt recycling?
Reclaimed asphalt is no longer considered waste these days, but is given a second life and reused thanks to asphalt recycling. This relieves the capacity of landfills and also conserves oil reserves. Thus, there are many economic and environmental benefits.
