SHERIDAN ROAD HIGHLAND PARK, ILL. CONSTRUCTED WITH TARVIA X 
Improving Macadam Roads 
Macadam roads won’t stand modern auto- 
mobile traffic. Every road builder and engineer 
knows this. The wear and tear of this traffic is 
far too great for the resisting capacity of the top 
surface. It is rapidly pulverized, dust is created, 
and at the end of a single season the road is often 
a melancholy ruin. ‘ 
To give macadam the additional binder 
which it so plainly needs to enable it to resist 
modern traffic, we offer Tarvia — a specially pre- 
pared coal tar preparation of the right grade, 
consistency and refinement for road purposes. 
Most of the road engineers throughout the country 
have used it with success. The Borough of 
Brooklyn, Greater New York, for instance, has 
just placed an order for 500,000 gallons. 
A tarviated road is durable, smooth, dustless 
and thoroughly waterproof. 
Tarvia is made in three consistencies. A, B, 
and X, to'suit varying conditions of road surface. 
C The cost of Tarvia applications varies with 
the thoroughness of the work, but in most cases it is 
more than saved by the reduction in maintenance 
expenses. It is frequently cheaper to maintain a 
dustless road with Tarvia than a dusty one 
without it. 
Tarvia is not an experiment, but is in regular 
use and has been adopted as standard in many 
localities. It is the only road preservative which 
has passed the experimental period.
