ROAD AT CYNWYDD, PA., MADE DUSTLESS WITH TARVIA 
Tarvia applied hot to a macadam road and allowed to solidify in the top dressing makes a 
hard, well-bonded surface capable of successfully resisting the wear of automobile traffic. It has 
been applied to hundreds of miles of roadway during the past three years with great success. 
The cost of the process, however, has somewhat hampered its widest possible use. 
With a view to meeting this one objection, we have now developed, after much experiment- 
ing, a new kind of tarvia, called “Tarvia B,” which may be applied to the road without heating 
and without special apparatus. 
The bonded surface thus secured is a continuous unbroken sheet somewhat similar to as- 
phalt in appearance. The surface is dustless and will not pulverize under automobile traffic. 
Rain torrents will not damage it. 
By the use of “Tarvia B” without heating, the cost is reduced to about $300 for a mile of 
roadway 16 feet wide, and one application will last a season under ordinary conditions. An 
annual renewal will keep the road permanently dustless. 
The Tarvia treatment is successful because it makes the road so hard and film that no dust is 
formed, whereas oils and soapy waters only dampen and keep the dust down after it has been created. 
An important economy in connection with “Tarvia B” is the omission of the top layer of 
fine stone screenings. 
A Tarviated macadam road costs less to maintain, and unlike ordinary macadam, is capable 
of meeting modern conditions brought about by automobile traffic. 
Booklets free upon application.
