The new BOMAG joins 10 others in the Bell fleet. The new BOMAG was soon put to work on an earthworks job preparing a house-building site. The machine was specified with a BOMAG Terrameter, an integrated measuring system which turns BOMAG single drum rollers into rolling pressure plates over the compacted surface area covering, in real time. Terrameter measures the level of stiffness (EVIB)in MN/m². EVIB correlates directly to the EV1/EV2 values from the plate load test. This means the operator not only sees the trend, but also the specific, absolute measured value of soil stiffness under the machine’s drum. The operator can then continue to work towards the required stiffness level specified by the client. The standard DIN set values for EV2 of 45, 80, 100 and 120 MN/m² are shown on the display as a step change. This allows the target achieved to be quickly displayed. Additionally, the operator is notified by a red LED that compaction has not increased between two passes.
