OAKWOOD BOULEVARD, CHICAGO, MADE DUSTLESS WITH TARVIA 
A NEW METHOD OF APPLICATION 
During the past three years hundreds of miles of American macadam roads have been 
successfully treated with Tarvia for the prevention of dust. The only obstacle to a much greater 
development of this process has been the expense of application. 1 his has been high because the 
Tarvia has to be heated, applied to the road while hot, and requires a covering of stone screenings. 
After numerous experiments we have now devised a slightly different compound of suit- 
able consistency which can be applied without heating. Careful tests have proved that it will 
give perfect satisfaction, and most macadam roads can now be made dustless for a season by a 
single application costing about $300 per mile of 16 feet roadway. 
The new compound of Tarvia, (which we call “Tarvia B”) penetrates into the roadway, 
reinforcing the binder. The surface thus obtained resembles asphalt and is equally dustless. 
Sprinkling may be entirely dispensed with. 
The binding effect of the Tarvia is such that additional protection in the way of a top 
coat of screenings over the Tarvia is quite unnecessary. 
We shall continue to recommend the application of “Tarvia A” applied hot with a top 
dressing of stone screenings for use on roads where the finest possible dustless macadam is de- 
sired. Where considerations of first cost are important, however, the cold application makes a 
superior and unequalled dust preventative at the lowest possible cost.
