The Dust Problem Solved 



THE problem of suppressing road dust is now receiving the attention of the best engineers 

 and road makers in all civilized countries. The suppression of this nuisance has become a 

 necessity, for not only does it damage crops and decrease real estate values but it is a 

 menace to health itself. 



Various methods have been tried, including sprinkling roads with fresh water, treating them 

 with calcium chloride, impregnating the road surfaces with crude oils of various kinds, etc., 

 but all of these methods have fallen short of their purpose. 



Within the past two years, following some experiments by French engineers, this company 

 introduced Tarvia, a special tar preparation. The results from this treatment have been unusually 

 successful. Some 800,000 yards of macadam roads were treated in about thirty different cities. 

 This included work at Jackson, Tenn., under the supervision of the United States Department 

 of Agriculture and work on New York roads under the supervision of the State Boards. It was 

 absolutely demonstrated that Tarvia not only suppresses dust but adds materially to the durability 

 of the road. It has been estimated that its use reduces the wear on the road itself about one-half, 

 and in this way the treatment practically pays for itself. 



To anyone interested we will gladly send booklet showing numerous 

 roads which have been treated, with full idata covering the subject,
