MADISON ROAD, CINCINNATI, O., CONSTRUCTED WITH “TARVIA X 
THE MADISON ROAD CASE 
Madison Road, Cincinnati, is an important macadam thoroughfare with very heavy travel with all 
kinds of vehicles. In the fall of 1907 it became clear that the macadam could not stand the traffic 
without excessive maintenance cost. Accordingly one section was treated with rock asphalt and an- 
other with “Tarvia X.” The balance was rebuilt in the ordinary style. 
In April, 1909, the Cincinnati Supt. of Street Repairs reported to the Board of Public Service that 
the tarvia section was in good shape. The rock asphalt section and the plain macadam, however, were 
“practically worn out,” and he recommended that these sections be resurfaced by scarifying, rolling, 
covering with a new course of 2-inch stone, and bonding with Tarvia X. 
A petition of 125 property owners along the road who suffered from the dust supported this rec- 
ommendation strongly. 
Further investigation showed that the Tarvia X treatment gave good results for two years. The 
rock asphalt lasted only six months. 
The Department, as a result of this experience, decided to use Tarvia X on three miles of the 
roadway. 
There is no material but tarvia now available for road treatment which will fill the small voids, 
solidify, form a plastic concrete, with the stone and stay there undamaged by the weather. Many 
asphalts disintegrate under the action of water. Oil has little or no bonding power; water-sprinkling 
actually hurts a road. Tarvia alone makes economical, low-maintenance, automobile-proof, dustless 
macadam. ^
