ROAD IN LINCOLN PARK SYSTEM, CHICAGO. CONSTRUCTED WITH TARVIA X 
As road engineers became familiar with Tar via they continually found for it new uses which 
were unthought of at the beginning. Tarvia A, which is applied hot and used with a finishing- 
coat of stone screenings, was the original Tarvia, and is now used on millions of yards of road- 
way every year for the prevention of dust and to preserve the road. Our largest customers are 
those who have had the most experience with it and the demand multiplies every season. 
Tarvia B, which is applied cold aird requires no special apparatus for application, was pro- 
duced to meet the demand for a dust layer to be used on highways where the more expensive 
and more perfect Tarvia A treatment could not be afforded. 
We now add Tarvia X, the result of several years experimenting. This Tarvia may be used 
in road construction and its wonderful binding qualities will add greatly to the life of the 
roadway. 
On a road built with Tarvia X the wear of automobile traffic does little damage, resultine 
in so great a saving in maintenance cost that the Tarvia treatment invariably effects a net saving 
when the costs are figured over a period of several years.
