CASE Construction Equipment has announced the all-new Tier 4 Final PT240D pneumatic tire roller. With an operating weight of 21,380 pounds (52,910 pounds at full ballast), a turbocharged 100-horsepower Deutz engine and a compaction width of 78.2 inches, the PT240D is built for sub-base and asphalt compaction on large-scale road and highway projects, airport runways and other large commercial developments. This pneumatic tire roller is designed to achieve compaction in fewer passes and provide improved penetration and compaction density ideal for today’s asphalt paving applications requiring tight density tolerances.
The tire configuration (four in front, four in back) with two-inch tire overlap “kneads” hot mix asphalt gently at the surface as it rolls across it. The result is greater asphalt density and fewer possibilities for voids that can lead to flaws/deterioration. The PT240D is designed to handle up to 31,530 pounds of ballast — including steel, sand and water — to meet the compaction requirements of any job. A large polyethylene water tank supplies a pressurized water feed system to prevent asphalt from sticking to the tires — and, at 103 gallons, allows operators to run for longer periods of time without refilling.
