Roadtec RX-900 Cold Planer
The Roadtec RX-900 is the big-production cold planer in the Roadtec family. Built for high-productivity half-lane and full-lane milling, it combines a Caterpillar C27 power package, heavy-duty construction, 14 in cut depth, wide cutter housing options, and a 42 in load-out conveyor.

Overview
Built for full-lane milling, half-lane highway removal, airport work, and maximum daily production.
The RX-900 is the machine contractors look at when production dominates the job. Astec calls it the most productive cold planer in the lineup, intended for high-productivity half-lane and full-lane milling.
The RX-900 carries the horsepower, weight, conveyor size, and cutter width options needed for long highway pulls, airport milling, interstate rehabilitation, and fast-paced DOT schedules.
Closner's role is helping Texas contractors pair that production with support: cutter tooling, parts planning, service response, truck-flow conversations, and practical advice on when the RX-900 is the right fit versus RX-700.

Dust Extraction
Dust extraction helps keep fine material moving into the haul truck and improves visibility around the milling operation.
Safe Functional Platform
Dual-side access and control stations help operators maintain line of sight during high-production truck loading and edge work.

How to compare it
Choose RX-900 when production and width matter more than compact transport or tight-space maneuverability.
Choose RX-700 when you need heavy-duty capability but not full-lane RX-900 output.
Choose RX-600 or RX-405 when most work is urban, utility, or parking-lot milling.

Frequently Asked Questions
RX-900 answers buyers search for
What is the Roadtec RX-900 used for?
The RX-900 is used for high-production asphalt milling, including half-lane and full-lane removal, interstate work, airport milling, and major DOT rehabilitation projects.
How much horsepower does the RX-900 have?
The current RX-900 spec sheet lists a Tier 4 Final Caterpillar C27 rated at 1050 hp.
How deep can the RX-900 cut?
Astec lists the Roadtec RX-900 maximum cut depth at up to 14 in.
Should I choose the RX-700 or RX-900?
The RX-700 is a heavy-duty 800 hp highway mill. The RX-900 is the larger production machine for full-lane or maximum-output milling where wider cutter options and a 42 in conveyor are worth the added size.
