What is it?
Intelligent Compaction
Why do it?
How to do it?
Our Goals …
We want to build long lasting, low
life cycle cost asphalt pavements
Meet or exceed project specifications
Our Goals …
We want to build long lasting, low
life cycle cost asphalt pavements
Achieve targets to receive full payment
Our Goals …
We want to build long lasting, low
life cycle cost asphalt pavements
Optimize rolling pattern for efficiency
Our Goals …
We want to build long lasting, low
life cycle cost asphalt pavements
Receive bonuses for density and/or
smoothness
Our Goals …
We want to build long lasting, low
life cycle cost asphalt pavements
Avoid costly rework (remove and replace)

Challenges …
Quality control is guess-work for
the operator
Knowing when temperature is right
Challenges …
Quality control is guess-work for
the operator
Maintaining the rolling pattern
Challenges …
Quality control is guess-work for
the operator
Rolling at the correct speed with vibration
Challenges …
Quality control is guess-work for
the operator
Making the right number of passes
Challenges …
Quality control is guess-work for
the operator
Remembering where passes begin and
end
Quality control is guess-work for
the operator
Limited real-time feedback can
lead to bad results
Shortcomings …
Rolling too Fast Under Compacted
Weak Sub-grade Over Compacted
Conventional tests are limited and
after the fact
Shortcomings …

Back to the What …
Instrumenting machines with this
technology creates an “IC Roller”
• Global Positioning System (GPS)
• Onboard computer reporting system
• Temperature sensors (for asphalt)
• Continuous measurement system
• Color display screen

Using the Technology
Demonstrations, test sites, training
and implementation
Operator training and “buy-in” is
key to success
Using the Technology
Connected
by Radio Link
RTK Base Station GPS Rover
Using the Technology
Real Time Kinematic (RTK) GPS is
recommended to improve accuracy

Using the Technology
Some systems offer machine-to-
machine communication
Recommendations
• GPS validation prior
to construction
• Use RTK corrections
• Pre-mapping when
possible
• Transfer IC data
daily
• Have QC/QA check
results
Require at least 70% of compacted
area with target passes or more
Benefits of IC
• Improve compaction … better performance
• Improve efficiency … cost savings
• Increase information … better QC/QA
