Worcester’s Experience with Tarvia 
Worcester, Mass., has used 380,000 
gallons of Tarvia for the preservation 
of its roads and the prevention of dust. 
The Tarvia methods were tried only 
after a prolonged and thorough investi- 
gation by the Mayor and Superintendent 
of Streets. All the street work that was 
done in the previous four years in east- 
ern Massachusetts, both with Tarvia and 
other dust layers, was carefully examined. 
The results of the first applications 
of Tarvia in Worcester were so satisfac- 
tory that the city is now purchasing sev- 
eral tank cars of Tarvia each week, and 
all new macadam construction in Wor- 
cester is being done with Tarvia X, the 
grade recommended for new work. 
In a public statement recently. Mayor 
James Logan states, “Tarvia speaks for 
itself. Thus far it has recommended it- 
self, and Tarviated streets are the best 
ones in the city.” No one who looks over 
the city can escape the same conclusion. 
A few of the streets treated with Tar- 
via are illustrated herewith. 
The advantages of the Tarvia treat- 
ment mav be stated as follows: 
The road lasts longer. Dust in dry 
weather and mud in wet weather are abolished. 
Heavy automobile traffic wears the road but 
little. Traction resistance is reduced. Frost 
and snow do not soften the road. 
Tarvia is made in three grades: Tarvia 
X for use in road construction. Tarvia A 
for use on the surface of macadam roads to 
preserve them and keep them dustless. Tar- 
via B for use as a dust suppressor.
