156 Allen Engineering has developed the new RS844 roller screed model with improved performance. The unit can be used for highway panel replacements, white-topping or airfield upgrades and is said to be a cost effective tool. The RS844 is the first of the new series of Allen spinning tube pavers and is a ride-on steerable roller screed powered by a 33kW 1265 Kubota diesel making it the most powerful roller screed on the market. The 203mm diameter paving tube is said to provide 25% more surface contact to the concrete than other roller screeds, which helps deliver a smoother concrete pavement. The RS844 is available in widths of 4.3-10.3m with working widths of 305-813mm.

Standard features include four lights located on the front and back of the machine, manual crank removable dolly jacks with foam filled pneumatic tyres, emergency kill switches on both ends of the machine and operator panel and 203mm diameter polyurethane coated drive rollers. They also include a sectionalised truss-style overhead mainframe and drive tube and paving tube scrapers to eliminate concrete build-up on tubes. Optional features include a 203mm  split reversible auger for machines up to 7.9m wide, a powered spray system for retardant application and a tow bar to move around the jobsite with a pick-up truck.
