Bringing compaction measurement technology to its mid-size tandem vibratory rollers for the first time, Bomag has introduced the Economizer system as an optional feature on its BW138AD-5 roller.

Bomag says its system saves time and money by providing operators with real-time data, thereby allowing continuous control of the compaction process. The BW138AD-5 Economizer uses an acceleration sensor to measure the stiffness of the target material across the entire compacted area. Data from the sensor is instantly displayed via a series of ten yellow LED lights on the roller’s instrument panel. The number of illuminated lights on the LED display increases in conjunction with increased compaction levels, allowing the operator to quickly react to changing conditions.

The Economizer signifies that maximum compaction has been achieved when the number of illuminated lights does not increase with subsequent roller passes. Additionally, a red LED light on the display warns of potential over-compaction, thereby preventing fractured aggregate. A sudden drop in the number of lit LED lights indicates a weak spot in the material, allowing operators to immediately analyze and remedy that particular area of the project.
