With an operating weight of 82,000 lbs. (37,195 kg), the SX-8 is capable of cutting up to 20 in. (50. 8 cm) deep and 100 in. (254 cm) wide and is designed for road rehabilitation, cold recycling or soil stabilization.

The SX-8e/ex is the largest in the Roadtec line of soil stabillizer-reclaimer machines. With an operating weight of 82,000 lbs. (37,195 kg), the SX-8 is capable of cutting up to 20 in. (50. 8 cm) deep and 100 in. (254 cm) wide and is designed for road rehabilitation, cold recycling or soil stabilization.

The machine's weight is evenly distributed between the two axles, which results in power being applied more efficiently. With weight balanced over the cutter, the machine is designed to handle the most challenging surface and ground conditions.

The SX-8e features a clean-running Tier IVi Caterpillar C18 755 hp (563 kW) @ 1,900 rpm engine, while the SX-8ex is equipped with a Tier III Caterpillar C18 700 hp (515 kW) @ 1,900 rpm, which is intended for lesser regulated countries. The engine provides power to the rotor through a direct drum drive.

The SX-8 rotor is designed for milling and mixing the most resistant soils completely and homogeneously. A variable geometry cutter housing enables the SX-8 to achieve material gradation with each pass. The variable geometry design positions the cutter in a way that promotes material sizing as well as the flow of the material. Heavy-duty front and rear doors are hydraulically adjustable for additional control of gradation and flow.

An air-shift 4-speed transmission is designed to allow the change of cutter speeds without a loss in production. The operator can select the appropriate cutter speed for the current conditions without making modifications to the cutter drive, saving time and effort.

The SX-8 cooling system pulls air from the top of the machine before it is exhausted through the radiator package. This design is intended to reduce the amount of dust traveling though the cooling system. Clean-out panels provide access for radiator maintenance.

The SX-8 was designed with operator comfort and visibility in mind. The ergonomic design of the sealed cabin situates the operator in position to reach all controls and systems. Joystick controls and four different steering modes supports the machine's maneuverability and operation. The operator seat slides laterally and swings 90 degrees to help provide the operator's preferred vantage point from which to work. The operator platform also slides 18 in. past the right of the machine for additional visibility.

The stabilizer-reclaimer's hydraulically-controlled suspension allows the depth of cut to be selected via push button. The machine is built on a rigid, sealed box frame designed to allow a controlled airflow while maintaining its durability. The SX-8 frame is built at Roadtec from strong A656 grade 80 steel, which is said to offer twice the yield strength of mild steel.

The custom-made machine frame is designed to perform in all terrains by providing substantial ground clearance. The wheels are suspended by four independently-controlled hydraulically adjustable leg assemblies that are bolted to the mainframe. The cutter housing also is securely fastened to the mainframe, providing strength and precision while the machine is working.
