Rosehill Cemetery, Chicago, lit., roacl constructed with Tarvia X 
Tarvia for Cemeteries and Parks 
' I v ARVIA is a dense, viscid pro- 
A duct of coal tar and is made in 
three grades. 
For road building use Tarvia X, the 
densest of the tarvias, and pour it into 
the broken stone after rolling, using it 
in every layer from the bottom of the 
road to the top, thus cementing the 
whole structure together in a tough, 
waterproof matrix. 
Such a road will give vastly longer 
service than ordinary macadam at 
trifling additional expense. 
Tarvia A, a medium density of tarvia, 
is forsurface applications. Itis applied 
hot as a liquid and solidifies on cooling, 
forming a matrix in the surface of the 
road and keeping the surface screen- 
ings from shifting and pulverizing 
under traffic. 
Tarvia B, the lightest and cheapest 
of the tarvia treatments, is primarily for 
dust suppression. It is applied from a 
sprinkling cart without heating, with or 
without the addition of stone screen- 
ings. One application will not only 
suppress dust for a season but the road 
will be waterproof, mudless, quiet and 
last much longer than ordinary water 
bond macadam.
