Ordinary macadam belongs to the past. It is not ade¬ 
quate to meet the demands of modern automobile traffic. 
It must be discarded or tarviated. 
A tarviated road costs a little more than ordinary mac¬ 
adam but lasts so much longer that the addition of the 
Tarvia is more than paid for in the reduction of main¬ 
tenance. 
Moreover, the elimination of the dust nuisance is in 
itself a great boon. 
Tarvia makes a firm elastic matrix around the stone, 
filling all voids, excluding water, and resisting pulveriza¬ 
tion of the surface. 
For an old road that cannot be rebuilt or resurfaced, 
the “sprinkling” or “surface” treatment known as “Tar¬ 
via B” treatment is highly effective. One treatment will 
give excellent results for a season, or even longer, de¬ 
pending upon the amount of traffic. This treatment is 
quite inexpensive. 
Tarvia gets at the original causes of road waste and 
disintegration. Oils and other devices simply make the 
dust too heavy to rise. They have little or no bonding or 
preservative properties. 
Tarvia is made in three grades:— 
Tarvia X for road construction. 
Tarvia A, for use in resurfacing old roads and keeping 
them dustless. 
Tarvia B, for dust suppression on old roads. 
Road Engineers, road authorities, automobile owners 
and residents along macadam roads are invited to send 
for our booklet covering the treatment in detail. Address 
nearest office.
