Oakwood Boulevard, Chicago, made dustless with Tarvia 
Automobile-Proof Surfaces 
The motor car has multiplied the labors of the road authorities. The modern road com- 
missioner sees his macadam, that formerly required little attention, stripped to the rock in a sin- 
gle season, by the wear and suction of automobile tires. Renewal of the top dressing that has 
been thus turned into dust is costly and unsatisfactory. 
Tarvia provides a way to make roads automobile-proof. 
The minute interstices of the macadam are filled with Tarvia in liquid form. When the 
Tarvia hardens a surface is formed that is elastic, waterproof and durable. Like asphalt, which 
it resembles, such a surface will not pulverize into dust. One treatment is enough for a season 
and only costs about $300 per mile of 16 ft. roadway. 
The new “Tarvia B” treatment may be applied without a protective cushion of fine screen- 
ings. Ordinarily when the larger stone are exposed they creep and work loose under the 
hammering of traffic. “Tarvia B,” however, has enough adhesive strength to hold the stones in 
place by holding the binding material in the road and as there is far more wearing capacity in 
the xYi inch stone than in fine screenings, remarkable durability is secured. Omitting the fine 
screenings removes a source of dust (the large stone will pulverize very slowly), and also saves 
heavy resurfacing expenses. 
Where a top dressing of fine stone is desirable for smoothness and sightliness, (city parks 
for instance, or in new road surfaces), “Tarvia A” is applied heated and while slightly more 
costly, the hot application gives an ideal smooth and dustless road.
