At bauma 2013 in Munich, BOMAG revolutionises the monitoring of compaction and launching its light tandem rollers with BOMAG ECONOMIZER. With this feature BOMAG becomes the first manufacturer to offer the roller operator a reliable instrument to indicate compaction progress. At last the industry has an instrument which shows the operator what is happening under the roller – it’s no longer just a feeling which determines quality during the compaction process. Thanks to the ECONOMIZER, the compaction status is continually displayed and soft spots identified.
Assessing the compaction, status has previously more or less been down to experience or instinct when it comes to light tandem rollers. As this approach can be unreliable, most operators stay on the safe side preferring to carry out a few passes too many, rather than too few. The time, effort, and expense can be significantly reduced by ECONOMIZER; expensive reworking is a thing of the past. ECONOMIZER produces reliable work results and excellent road paving quality particularly in inner-city areas on cycle lanes, footpaths, car parks, and service roads, where the roller operator has previously had no support in making decisions.
Simplifying compactionThe ECONOMIZER display is situated on the machine dashboard. It displays compaction progress in real time with the aid of an LED indicator. Regardless of whether it is used on earthworks or on the most diverse asphalt layers, ECONOMIZER reliably analyses the load bearing capacity of the subsoil and reflects this in the increasing number of yellow LEDs illuminated on the display. When the number of LEDs stops increasing, compaction is complete. By means of proven sample compaction measuring equipment, such as Troxler or PQI probes, ECONOMIZER can be calibrated to the density values. Furthermore, the ECONOMIZER also detects weak spots in road sub bases. The operator locates these with any sudden decrease in “compaction” LEDs. Roller jump operation and the risk of aggregate crushing are also indicated to the operator by the last red LED lamp in the ECONOMIZER display.
