Where we Started?
Road rollers have been
around for over 250 years
(mid 1700’s)
Early 1800’s rollers were
made of stone & cast iron
and filled with water or stone
& pulled with 1 hp.
Manufacturing of rollers
started in the late 1800’s &
early 1900’s
1800’s - 1925

Based on the acquisition
of a patent for vibration of
Concrete
Rollers 1925 - 1975
Note: First experimental vibratory rollers were
developed in the 1930’s

Why Intelligent Compaction?
Shortcomings in the Compaction Process…
Limited “On The Fly”
Feedback
Over or UnderCompaction Can Occur
Sampling Coverage
1 / 1,000,000
100 %
Coverage
Practical example:
Counting of passes
1-3 passes
Up to 13
passes
Consistency
Up to 15
passes
1 pass

HCQ System
Difference between earthwork and soil
Bearing capacity
%
HCQ-GPS
Compaction Degree
Stiffness
is not the same as
compaction degree!
(% Density)
HCQ-GPS
What are other States
doing?
FHWA - EDC
Other IC FHWA Projects

2014
Summary
We have come a long way
single horse stone rollers
Static 3-wheel rollers
Tandem vibration rollers
Pneumatic rollers
Oscillation rollers
Intelligent rollers????
Why IC?
QC Tool
Consistency
Permanent Record
FHWA
More consistent product
Overall Benefit:
Combining current technology
Improved Pavement performance!
Thank You
