Demonstrating a Single-Drum Vibratory Roller on Your Own Soil or Aggregate
A buyer's guide to planning a single-drum vibratory roller demonstration using the buyer's actual material, with practical checks for the RFQ, trial, and acceptance test.
Before accepting a demonstration, decide whether the roller will be trialled on the buyer's own soil or aggregate rather than on a supplier-prepared pad. For a single-drum vibratory roller used in compaction, that choice shapes every later comparison: a machine that looks capable on uniform material may behave differently on the gradation, moisture, and layer depth the buyer actually places.
Build the trial around the buyer's material. Ask the supplier to confirm the layer thickness and area to be compacted, how many passes will be run, and whether both vibration frequencies, 35 / 40 Hz, will be demonstrated. Reference values for the model include an operating mass of 12,800 kg, rated power of 93 kW at 2,200 rpm, and a drum diameter of 1,555 mm; treat these as catalog figures, not guarantees for a supplied unit. Agree in advance how compaction will be assessed, and record the settings used for each pass so results can be compared.
Before requesting a quote, confirm with the supplier what material and volume the buyer must prepare, who supplies and levels it, which machine configuration will be demonstrated, and how the trial results will be documented and tied to the acceptance criteria.
