Current Offering from CaterpillarIntelligent Compaction on asphalt is currently used as a process control tool, and not necessarily a direct measure of compaction. Value is seen when utilized to:
1. Count and map number of passes in order to get proper coverage and compaction passes on the entire road surface as to improve rolling patterns
2. Measure and map the temperature of the mat while compacted in order to be certain compaction passes take place at a temperature where compaction is effective

What does it take to compact asphalt?
Mix Temperature – or nothing else matters…
Machine• vibratory systems• dynamic forces
Operator – performs the rolling pattern• Where did I stop on the previous pass?• Did I go back far enough on the return pass?• Did I provide enough overlap on the previous pass?• Is the mat temperature too hot, too cold?• Night paving?

Rolling Patterns
• Take density measurements to establish a rolling pattern
• Established patterns will vary as environmental changes occur throughout the day
• Changes in the mix can affect rolling pattern
![Page 28: Intelligent Compaction€¦ · PAVING PRODUCTS Current Offering from Caterpillar Intelligent Compaction on asphalt is currently used as a process control tool, and not necessarily](https://reader030.vdocuments.us/reader030/viewer/2022040605/5eaab2aa53eb72017c41ce42/html5/thumbnails/28.jpg)

Definition: Rolling Pattern (asphalt)
“A rolling pattern is the number, type, and sequence of rollers used in a specific, repetitive pattern that will meet or exceed the density and ride quality specifications for the project.”

Not a direct measure of compaction, rather, data for process control on asphalt
• Dual infra-red sensors mounted on the front and rear of machine deliver real-time readings
• Keep operator informed of when to begin rolling and when to stop
• Help avoid tender-zones that often occur in the 95º to 115º C (200º to 240º F) temperature range

Mapping PassesThis illustration provides the pass-count mapping that occurred in the Minneapolis Global Paving parking lot. The colors signify the number of times that the drums hit a specific area.
Green – Target pass-count was metBlue – Target pass-count not met;
1 more passes neededRed – Target pass-count not met;
2 more passes needed
* Note: The red slivers within the paved areas indicate that there wasn’t proper drum overlap

Why is Pass-Count mapping important?
• Following established rolling pattern• Efficiency – fuel, machine wear• Eliminate excessive overlap• Prevent incomplete passes, stopping
short or missed• Roller stops and bumps in the mat• Easier night-time operation

Why is temperature important?Understanding the asphalt temperature helps operators and supervisors determine when the asphalt can be compacted.
• Monitoring plant/trucking temperature maangement
• Upper temperature limit that permits compaction is normally around 149C (300F)
• Lower limit that permits compaction is normally around 80C (175F)
• Avoid “tender zones” if one is present

1. What accuracy of GPS is required?2. What happens if/when GPS signal is lost?3. What is the expectation for data transfer? Daily?
Wireless? USB? Printout?4. What data collection/processing software is required?5. Does it need to be VEDA-compatible?6. Is training required? By the Dealer? OEM?7. Is a “Work Plan” required by the Contractor?8. Are accelerometers specified, or only IC-MV (can MDP
be used?)
