The Three Musketeers Ride Again This time they're rolling along
with a little box to keep them in line by John S. Ball III No,
this is not your typical bedtime story. Put the kids to bed and
I'll tell you how to get compaction using the three different
types of rollers - with the assistance of a little magic box
better known as the nuclear density gauge.What is compaction?
Simply put, it is the act of compressing a given volume of
material into a smaller volume. In asphalt paving, compaction is
usually accomplished by rolling with steel wheeled, pneumatic
tired or vibratory rollers or a combination of those three. How
you achieve compaction depends on a combination of different
variables.Some of these variables include mix design,
temperature of the mix, speed of the paver, vibration from the
screed, roller types being used, weight andwidth of the rollers,
and amplitude and frequency of the rollers. How do you check
whether you have compaction density or not? You check it with a
nuclear density gauge. Nuclear
