Roadtec Inc. introduces the new powerful, heavy-duty rubber tire RP-190e asphalt paver. The new design offers operator comfort and safety with 360-degree visibility, fingertip controls, fully adjustable seats, low noise levels and fume extraction systems. The exclusive Roadtec anti-segregation design gives consistent pavement quality with this tough and dependable paver.

Redesigned operator stations provide greater efficiency and comfort, including hydraulic-pivot consoles and selectable seat positions. Among the numerous design refinements are a new adjustable delta plate design, redesigned hydraulic tunnel panels for improved accessibility and lower deck height.

Oversized variable displacement pumps are used for propel and feed systems on all Roadtec pavers. The high-capacity pumps can run at optimum speed to keep components cool, leading to longer component life. Access to hydraulic filters and test ports has been greatly improved by clustering these components in one easily accessed location. Release agent spray-down systems are standard and include a dual system, one for diesel the other for release agent.

A heavy-duty, anti-segregation feed system is standard on the RP-190e. The feed system is designed with durable, abrasion resistant components to combat segregation while lowering operating costs. Full offset link conveyor chains and chromium carbide clad floor plates increase the life of the wear parts and decrease the time spent on machine maintenance.

The full offset link chains have a higher tensile strength increasing the chains’ wear life. The chromium carbide clad floor plates are dropped in, requiring no bolts and an exceptionally low amount of maintenance time. A new dual hinge apron plate design allows easy access and clean out of the conveyors.

Electric flow gates and 18 in. (457 mm) hydraulic tunnel extensions provide control of material flow from the hopper to the screed. Cast 16 in. (406 mm) diameter Ni-Hard augers can be hydraulically lowered, raised and tilted for increased control over material segregation. The augers can be operated independently of the conveyors giving the operator complete control over the material.

The RP-190e comes standard with the guardian remote telematics system. With guardian, the machine’s electrical system, hydraulic system, engine, pressure transducers, auger speed sensors, flow gate height and fuel consumption can be closely monitored in real-time via cellular signal. The guardian system allows owners and service technicians to obtain production data for the paver. The guardian system will automatically email all fault codes and maintenance reminders.

A Cummins Tier IV interim, 230 hp. (169 kw) engine powers the new paver. The standard cooling package includes a variable speed, hydraulically driven fan providing lower noise levels and better fuel efficiency.

The RP-190e will be on display in the Central Hall of CONEXPO-CON/AGG 2014 in booth #50327.

In addition the SX-8e reclaimer-stabilizer will be on display.
