BOMAG at bauma 2013:
Light tandem rollers with BOMAG ECONOMIZER

At bauma 2013 in Munich, BOMAG will revolutionise 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 that ensues can be significantly reduced by the ECONOMIZER – expensive reworking is a thing of the past. The 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 compaction
The 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, the 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, the 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. By responding quickly to this signal, the operator can preserve both the material being compacted and the machine. Another advantage of the BOMAG ECONOMIZER is its easy operation and clear display, which even inexperienced operators will find easy to navigate. Additional instruction or training courses are unnecessary. The ECONOMIZER always functions automatically when the drum vibration is activated. These constant checks mean the roller operator will reduce the number of unnecessary passes, to save the contractor time and money.

Long-term investment: ECONOMIZER and the latest engine technology
BOMAG ECONOMIZER is now optionally available for tandem rollers in the new 5th generation BW 80 to BW 138. All new tandem rollers follow the series design and use future-proof engines complying with the latest exhaust classifications. At bauma 2013 in Munich, BOMAG will be displaying the BW 80, BW 100 AD-5, BW 120 AC-5 and BW 138 with ECONOMIZER. Furthermore, several machines will be in use at the "City Action" demonstration grounds, where visitors will be able to examine them in detail.
Quality at a glance: the BOMAG ECONOMIZER display is directly integrated in the tandem roller dashboard.

The BOMAG ECONOMIZER also detects hidden soft spots.
