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

RTK Base Station GPS Rover

Using the Technology

Real Time Kinematic (RTK) GPS is

recommended to improve accuracy

software

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
