Roadtec Cold Planer
Roadtec RX-700 Cold Planer
The Roadtec RX-700 is the heavy-duty highway-class cold planer for contractors who need more horsepower, deeper cut capability, and wider cutter housing options than a mid-size city mill. With 800 hp, balanced weight distribution, and standard widths up to the 10 ft 6 in class, it is built for serious production without jumping all the way to the RX-900.
Power
800 hp Cat C18
Cut depth
Up to 14 in
Cut widths
6 ft 7 in to 10 ft 6 in
Conveyor
36 in belts
Overview
Built for highway milling, deeper cuts, heavier production, and 8 ft to 10 ft-class work.
The RX-700 is the bridge between urban production and high-output full-lane milling. It carries an 800 hp Caterpillar C18, cuts up to 14 in deep, and is available with three-track or four-track assemblies.
Astec describes the RX-700 as a heavy-duty machine designed around balanced weight distribution and user-friendly operation and maintenance. That matters when crews are cutting deeper, loading trucks all day, and still need accurate grade control.
For Closner customers, the RX-700 is often the machine to compare for state highway work, airport shoulders, industrial paving removal, mill-and-overlay packages, and other jobs where RX-600 size is not enough but RX-900 capacity is more than the job needs.
Features
What makes the RX-700 work
Rear Object Detection
Rear detection helps stop the cold planer when a person or object is behind the machine while it is backing up.
Operator Platform
The platform is designed for access from either side, with dual stations so crews can keep sight lines on trucks, edges, and ground personnel.

How to compare it
Choose RX-700 over RX-600 for 800 hp, 14 in cut depth, and larger cutter width options.
Choose RX-900 when the project requires full-lane production or the widest standard housings.
Choose RX-405 or RX-600 when access, transport, and urban maneuverability are more important than production.
