Remote Air Compressor
Onboard air powers pneumatic tooling at the jobsite, making tooth changes faster and reducing the need to bring a separate compressor into the work zone.

Roadtec SX-6 Soil Stabilizer / Reclaimer
The Roadtec SX-6 is the mid-size Roadtec stabilizer/reclaimer for contractors who need a rare combination of horsepower, mobility, and application flexibility for soil stabilization and asphalt reclamation.
Power
675 hp Cummins QSX-15
Cut width
100 in
Max cut depth
20 in
Shipping weight
83,000-83,480 lb
Where it fits
675 hp, 100 in cut width, and 20 in max depth in the more mobile SX platform.
The SX-6 sits in the sweet spot for contractors who need serious production without stepping into the largest stabilizer in the lineup. Astec lists a clean-running 675 hp Tier 4 Final Cummins QSX-15 package, a 100 in standard cut width, and up to 20 in maximum cutting depth.
For Texas contractors, that means one machine can handle full-depth reclamation, base stabilization, cement or lime treatment, and project work where mobility and job-to-job transport matter.
Closner supports the SX-6 conversation with Roadtec application help, parts, service coordination, tooling guidance, and practical sizing advice before you quote a stabilization or reclamation package.
Mid-size Roadtec stabilizer/reclaimer platform
Direct drum drive with a four-speed manual transmission

Feature details
Built for stabilization and reclamation work
Bi-Directional Travel
A rear control box lets the operator run the machine in reverse when the application calls for controlled backward operation or repositioning.
Sealed, Pressurized Cab
The enclosed cab is temperature-controlled and pressurized to help keep the operator protected from dust, weather, and jobsite noise.
Application-Specific Drums
Soil stabilization and asphalt reclamation drums let crews match cutter tooling and gradation to the material, depth, and production target.
Water & Emulsion System
The additive system gives operators control of water, emulsion, or foamed asphalt delivery with flow control and nozzle activation.
Guardian Telematics
Guardian telematics gives owners and service teams machine visibility, diagnostics, and support information from the field.
