This month, Equipment World launches a new seven-part Road
Science series on how to optimize pavement construction to win
those bonuses.
We start at the very foundation of the overlay, the milled
asphalt surface, and then look at each aspect of paving both
asphalt and concrete pavements:
Milling drum is the
heart of the cold
milling sequence;
here worn cutting
tools are replaced
on the job site.

A
milled surface with the right pattern, grade
and slope is the key to a super-smooth as-
phalt overlay that wins the smoothness, den-
sity and performance bonuses (now so critical
to contractor profitability).
In just over three decades, asphalt cold milling equip-
ment, also called planers or grinders, has matured in terms
of durability, complexity and choice of makes and models.
Operators are under pressure to get the best perfor-
mance out of their cold mills in terms of consistency of
