Did I make all of my passes? Did the compactor ahead of me miss any areas? Is the mat too cold to continue compacting? With Machine-to-Machine technology, compactors can share this information with each other, keeping the operators informed during the project and help increase efficiency and productivity.
Mapping Pass-Counts and Rolling Patterns
Options are available for asphalt compactors to help operators maintain uniform rolling patterns. Screens in the operator’s compartment can be programmed to show the operator where the roller is located on the mat and how much of the pattern has been completed.
Global positioning systems provide very accurate maps of rolling patterns. The control can be programmed with the required number of passes. Then, the screen will display different colors as the passes are completed. The operator no longer has to guess at the end of the pattern for reversing. And, there is less chance that the operator will miss any of the areas in the pattern because the screen provides immediate feedback for quick corrective action.
Temperature is Key
Dual infra-red temperature sensors mounted on the front and rear of the machine deliver real-time temperature readings. The sensors are continually cleaned by compressed air that keeps dust, fumes and moisture away from the sensor lenses. The temperature system is accurate and provides constant, visual reference at the operator’s station display. Not only does the operator know where the machine is located in relation to the defined rolling pattern, the operator knows where the machine is located relative to the desired temperature zone. Temperature Mapping provides a visual readout of mat temperature in order to keep the machine in the proper temperature range, informing the operator when to begin rolling and when to stop.
Sharing Data Between Compactors
The Machine-to-Machine Communication system assists in keeping rolling patterns coordinated by sharing coverage and pass-count maps via the operating displays of multiple machines. By viewing the color display, operators can monitor areas of coverage and the number of passes made. If a trailing operator identifies an area of missed coverage, the deficiency can be immediately corrected to ensure consistent coverage. The system facilitates echelon compaction when multiple machines are executing rolling patterns.
This technology is especially helpful during nighttime operation when it’s difficult to see where the compactor has been. Real-time visual references for passes made and mat temperatures reduces inconsistencies in the rolling pattern. Without the system, operators might question the stopping point on a previous pass or return pass, whether pass overlap was sufficient, or whether mat temperature was in the proper range.
Now you can know if you’ve completed all your passes, if the compactor ahead of you missed any areas and when the mat is too cold to continue compacting. Compaction is essential to the durability of a road and Cat® COMPACT technology is now making it easier to ensure you’ve covered every inch.
