Compare Roadtec SX-6 and SX-8 soil stabilizers/reclaimers for full-depth reclamation, soil stabilization, asphalt reclamation, pulverizing, and cold recycling work across Texas.
Improve weak base material with cement, lime, fly ash, or other stabilizing agents before paving.
Pulverize existing pavement and base into a reusable, engineered road structure instead of hauling everything off.
Reclaim existing asphalt into a consistent gradation for road rehabilitation, base repair, and recycling work.
How to choose
Stabilizer sizing is not just horsepower. The correct Roadtec package depends on existing pavement thickness, base material, target gradation, cement or lime spread rates, water/emulsion delivery, working width, transport, and how much production the crew must hold every day.
Roadtec SX lineup
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.
The Roadtec SX-8 is the largest and most powerful stabilizer/reclaimer in the Astec Roadtec lineup, built for contractors who need high-production stabilization, pulverizing, and cold recycling capability.
Stabilization projects live or die by setup: drum selection, tooth pattern, gradation, additive delivery, water supply, support trucks, and downtime planning. Closner can help your team think through the full stabilization package before the machine hits the road.
