Continuous Compaction Control (CCC) is designed to increase the productivity and quality assurance of material compaction. BOMAG CCC avoids unnecessary passes and can reduce the number of compaction tests by up to 66%. Quality assurance is dramatically simplified and improved with the continuous recording of positioning (GPS) and compaction data, which can be analyzed and stored for future reference.
The 3-stage BOMAG CCC process is:
Information is displayed in the cab using ECONOMIZER or TERRAMETER which allows the machine’s operator to optimize compaction.
In automatic mode, the machine continually adjusts the compaction force delivering ‘intelligent compaction’.
The entire compaction process is recorded and documented using one of the 3 BOMAG Compaction Management (BCM) systems which allow analysis using BCM Office and data storage for quality assurance purposes.
A machine’s operator can achieve the desired level of compaction, quickly, easily and with repeatability on earthworks and asphalt with these displays. The visual displays help the operator minimize the number of passes and avoid under and over compaction.
Available on BOMAG trench compactors, reversible plates, light and heavy tandem rollers, ECONOMIZER measures and displays real-time compaction progress through an array of LED lights. ECONOMIZER saves time and money by reducing the number of passes required and under and over compaction is avoided.
Available on BOMAG single drum rollers the TERRAMETER measures dynamic soil stiffness in real-time and displays it on a screen in the cab. BOMAG’s unique system uses two accelerometers in the drum to determine the soil stiffness under the machine as it rolls. The displayed value is directly related to the deformation modulus EV2, of the static plate load test to DIN 18196. The clear display shows the DIN standard values which help the operator to achieve the target value. The display also shows the machine’s vibration frequency and travel speed at any time. A red warning light shows if compaction has not increased on two consecutive passes. An optional in-cab printer is available. This invaluable aid prints a report that shows the average, maximum, and minimum compaction over a 150-metre long pass.
VARIOCONTROL – Earthworks
The fully integrated VARIOCONTROL system allows both manual and fully automatic control of directed vibration, generated by the unique VARIO exciter system optimizing the compaction process. The system is effective in pre-load compaction, high-energy deep-impact compaction up to 5m in depth, and low-energy surface compaction. In automatic mode, the machine’s operator sets a target EVIB value related to the EV2 plate load test, and the machine does the rest, automatically adjusting the compaction energy as it rolls until the target value is met. In manual mode, the operator can set a fixed amplitude of vibration from 6 options.
ASPHALT MANAGER 2 – Asphalt
Available on large tandem rollers AM2 is an intelligent compaction system with manual and automatic modes. In the automatic setting, the system continually adjusts the vibration’s amplitude and direction giving a high-quality finish and consistent compaction across large areas. AM2 uniquely matches the direction of vibration to the direction of travel, which prevents a ‘bow-wave’ effect. When stationary the machine selects horizontal vibration, which prevents the machine sinking into the asphalt. The system is particularly effective on thin layers or when used to roll hot and cold joints. The visual display shows the current effective amplitude, the EVIB value and the surface temperature of the asphalt.
These BOMAG developed systems provide complete CCC for managing a project. BOMAG CCC delivers productivity and quality assurance on any size of a job including the largest and most complex projects for road, rail and major infrastructure.
BOMAG Compaction Management (BCM) uses a robust tablet computer, mounted in the cab, to measure, display and record compaction data. GPS information can be integrated using BCM StarFire. The BCM system is modular and can be upgraded at any time.
This ‘entry-level’ plug-and-play system shows the operator the number of passes using different colours. The system is very easy to use. The operator presses start, rolls, and stops when the required number of passes have been made, which is shown on the display. BCM records the compaction data in the tablet computer which can produce reports for transfer to a PC for analysis and storage.
This ‘top-of-the-range’ system provides full CCC and turns a roller into a powerful quality assurance tool. The tablet computer records and displays EVIB and ECONOMIZER values and the number of completed passes, creating a map of the complete compaction process. BCM 05 can import points and lines from another geographic information system (GIS) applications. Data is easily transferred to a PC which allows detailed analysis and long-term record keeping, for the ultimate in quality assurance.
On large projects, several rollers often work together. BCM net turns them into a coordinated team by monitoring and displaying all movements to all drivers, who then have a view of the complete picture showing the number of passes made on each section of the job. BCM net establishes a direct WLAN link to all the rollers allowing them to communicate with one another optimizing compaction avoiding unnecessary passes which save time, money, and fuel.
This integrated system gives any large BOMAG roller a continuous GPS and GLONASS signal accurate to +/- 200mm. The system, which integrates with BCM 05, allows accurate mapping giving full CCC on large and complex jobs. The system, which includes a tablet computer, software, and a roof mounted GPS receiver, can be factory fitted or retrofitted at any time. On very large-scale jobs local transmitters can be integrated into the mix to increase accuracy to +/- 50mm.
