Wie Dust Layi 



Road in Oyster Bay, L. 1., made dustless with Tarvia 



The Prevention of Dust 



THE use of Tarvia for the prevention of dust on macadam roads is based on the principle that only 

 a dustless road can be considered rightly built. 



Tarvia acts as a binder on the top surface of the macadam, thereby creating an elastic, waterproof 

 and frostproof surface which does not readily pulverize under traffic. 



One treatment with Tarvia lasts about a year and the next treatment will probably last two years, less and 

 less Tarvia being required the longer the process is maintained. 



Tar\'ia must not be confused with the "sticky" sprinkling liquids which are temporary in their effect, and, 

 in the end, costly. 



Tarvia is a genuine road improvement, reaching the basic cause of dust and wear. It has been thoroughly 

 tested by Federal and State engineers, and has received the official stamp of their approval as a means of 

 suppressing dust. 



It has been adopted for universal use by the authorities in several cities. Thirty cities made practical use of 

 it during the last summer. Moreover, this process is not a new thing, but has been employed all over Europe, 

 especially in FVance, since 1900, and is now generally recognized as the only standard method for the suppression 

 of dust on macadam roads bearing heavy traffic.
