A road in the Metropolitan Park System, Boston, built with Tarvia X 
The Ideal Park Road 
For parks and cemeteries, the requirements for a 
proper road surface are that it shall be dustless, 
quick drying, mudless, noiseless, cleanly and dur- 
able. Tarviated roads fulfill these requirements per- 
fectly. 
Tarvia may be applied by various methods. In 
all cases, its function is to act as a binder, filling all 
voids among the stone and sealing up the surface 
with a tough, waterproof matrix. The slight plastic- 
ity of this surface enables it to resist strains under 
which ordinary macadam pulverizes. The transpor- 
tation of heavy monuments, for example, which is 
an incident to cemetery usage, breaks down the 
surface of ordinary macadam and causes internal 
movements which are very destructive to the road. 
Tarviated roads bear such strains as these perfectly, 
I and in fact, are improved by such heavy rolling. The 
same is true to a certain extent of park roads that 
are subjected to automobile traffic. Automobiles do 
not hurt a Tarviated surface, but tend to roll it down 
smoother. 
Tarvia is waterproof and a Tarviated road dries 
immediately after a rain and always furnishes good 
footing. 
Tarvia is made in three grades to satisfy varying 
requirements: — Tarvia X, the heaviest and densest 
grade is for use in the large voids of new roads and 
is applied during constructon or resurfacing opera- 
tions. Tarvia A, less dense than Tarva X, is for 
thorough surface work, while Tarvia B, which can 
be applied without heating, is a liquid that is simply 
spread over an old road surface into which it pene- 
trates and hardens.
