Statistics We Should Know:
Federal = 3%
State
= 20%
Local
= 77%
2/3 are Paved (1/3 Unpaved)
94% of Paved have an Asphalt Surface

The Stakes are LARGE!
 $2 Trillion Investment in
Transportation Infrastructure.
 There are MANY owners.
 There is shared expertise.
 Our Country DEPENDS on
Our Success!!!
