U. S. Naval Training Station, Great Lakes, North Chicago, 111 ., Roads treated with Tarvia X 
Tarvia at a Government Station 
permits the use of the more durable large stone close 
to the surface. 
It has long been recognized by engineers that large 
stone pulverized and wore away much more slowly 
than the carpet of fine screenings with which ordi¬ 
nary macadam roads must be covered, but the tend¬ 
ency of the large stone to shift and ravel has previ¬ 
ously prevented the use of the large stone in this way. 
Tarvia X makes it possible to use materials to 
vastly better advantages and preserves the road so 
long that the cost of the Tarvia itself is more than 
paid for. 
The government engineers chose Tarvia for econ¬ 
omy. Incidentally, they secured dustlessness, a re¬ 
duction of noise, freedom from mud and an im¬ 
proved appearance. 
Illustrated Booklets on request to nearest ofdee. 
T he new Great Lakes Naval Training Station 
near Chicago rivals Annapolis and West Point 
in its fine equipment and the thorough and 
finished development and beautification of the 
property. 
It has many macadam roadways, some of which 
carry an especially heavy traffic, built with Tarvia X, 
for the purpose of keeping down maintenance costs. 
In appearance, these roads resemble sheet asphalt, 
being clean, firm under foot and free from dust. 
In durability, they will, of course, far exceed ordi¬ 
nary macadam, for they are bonded with the dense 
viscid Tarvia for several inches in depth. 
The Tarvia fills the voids, keeps the stone from 
creeping or shifting under the weight of traffic, 
eliminates abrasion due to internal movement of 
the stone, excludes water and frost, and best of all.
