The Rubble Master RM 120X establishes itself as a mobile solution for asphalt recycling on construction sites. Presented by distributor Christophel, this compact impact crusher combines crushing and screening in a single machine. The concept targets companies that process medium volumes of road demolition materials.
The machine displays a theoretical throughput of 250 tons per hour on asphalt materials. The feed opening measures 1,200 × 700 mm, sufficient for blocks from milling. The rotor equipped with four percussion bars rotates at 650 revolutions per minute. The two-stage integrated screen allows separation of three particle size fractions directly at the outlet. This configuration reduces reworking operations and saves a separate mobile screening station.
The mobility aspect makes the difference compared to fixed installations. The RM 120X is transported on a standard semi-trailer without prior disassembly. The weight of 31 tons remains within normal road transport limits. Setup on site takes less than 30 minutes according to the manufacturer. For excavation companies working on multiple sites simultaneously, this flexibility represents a direct economic argument.
The asphalt material recycling system generates reusable aggregates for foundation or base layer. The 0-8 mm, 8-16 mm and 16-32 mm fractions are sorted directly at output. The quality of the grain obtained depends on the adjustment of the gap and rotation speed. On site, this means less transport to fixed installations and immediate valorization of excavated material. The carbon footprint improves, landfill disposal costs decrease.
The RM 120X fits into the circular economy trend on road construction sites. Companies investing in this type of mobile crusher are betting on the continuous increase in landfill taxes and stricter recycling obligations. The machine is positioned between small crushers under 20 tons and heavy installations over 50 tons. It targets the SME construction segment looking to internalize the treatment of their construction waste.
Christophel supports the launch with a service package including operator training and preventive maintenance. Supply of wear parts, particularly percussion bars and screens, determines medium-term profitability. On a road resurfacing site, the RM 120X can process the equivalent of 2 km of road per week depending on the coating thickness. This capacity allows considering amortization over three to four years for a company operating at full capacity. Pricing details and feedback after the first months of operation will determine actual market acceptance. For now, the technical concept convinces on paper. Real-world sites will provide the definitive figures.
