The Passing of Plain Macadam 
"In these days of progress it is a misdemeanor bordering closely on crime 
to put an old style macadam pavement 
W ITHIN the last ten years the char¬ 
acter of traffic on our roads has 
changed completely. A large part 
of it is now motor traffic, and the wheels'^ 
instead of simply rolling over the road, 
tear up the surface. 
The driving wheels of an automobile 
revolve several more times to the mile than 
front wheels of the same size, showing the 
existence of a certain amount of slip, and 
accounting clearly for the rapid deteriora¬ 
tion of brittle macadam surfaces under 
such traffic. 
Deterioration means dust. It also means 
frequent renewals of the surface at great ex¬ 
pense. Obviously, the way to prevent dete¬ 
rioration and to lower maintenance charges

is to make the road surface proof against 
the shearing action of driving wheels. 
This can be accomplished by the use of 
Tarvia, which re enforces the surface giv¬ 
ing it a plasticity and tenacity which will 
enable it to resist automobile traffic. 
Tarvia was the first bituminous binder 
on the American market, and conforms to 
universal European experience. It is made 
in three grades—“Tarvia X” for road and 
pavement construction, “Tarvia A” for 
surfacing, “Tarvia B” for dust prevention 
and road preservation. 
Our expert advice is at the disposal of 
any one interested. Illustrated booklets 
regarding the Tarvia treatments free on 
request to nearest office.
