of Buffalo, and were viewed by many 
delegates to the convention, two of them 
being visited officially by the delegates 
on the afternoon of the second day of 
the convention 
The delegates also visited the repair 
and maintenance work being done on 
the Main street road. Section No. i, 
between the City Line and Williamsville, 
where bad ruts were being patched af- 
ter the application of Tarvia B by paint- 
ing them with Tarvia A and leaving a 
surplus sufficient to force up through the 
three-fourth-inch stone with a five-ton 
asphalt roller. If the tarvia did not 
come to the surface more was added 
and, with another coating of screenings, 
was thoroughly rolled. 
A badly rutted and neglected state 
road, known as Main street road. Sec- 
tion 2 (length, 1.93 miles; width of 
macadam, 16 feet), was repaired and 
placed in excellent condition during the 
convention and the few days preceding. 
This work was done by the addition of 
two-inch stone and screenings thorough- 
ly rolled and puddled, using a ten-ton 
road roller and two 600-gallon sprink- 
lers. 
In this connection attention is called 
to the use of road preservatives and 
dust-laying applications. 
Calcide being especially adapted for 
use on roads where dwellings are ad- 
jacent, the Calcide Process Company of 
Boston treated a section in the residental 
district of Buffalo for the Good Roads 
Convention. An exhibition was made of 
the methods of applying the calcide from 
a two-horse water cart outfit to a gar- 
den-hose attachment, the latter being 
used where water carts are not avail- 
able. The forty per cent calcide was 
shipped from Syracuse to Buffalo in a 
tank car, then drawn off into a specially- 
fitted cart and mixed by a mechanical 
process, patented by the Calcide Process 
Company, and then applied to the roads. 
One hundred and ten gallons of forty 
per cent liquid was mixed with four 
hundred and ninety gallons of water, 
and the resultant solution applied to 
nineteen hundred square yards of road 
surface from the water cart. A second 
application was made a few days later 
and the road was in condition to go, 
with a coat of water now and then, for 
three weeks before another application 
should be necessary. 
The cost of application, including 
team hire, was three-tenths of one cent 
per square yard for one application ; 
allowing for ten applications during the 
season, the cost of the calcide and its 
application should be three cents per 
square yard, with an allowance of one 
cent for incidental expenditure and 
whatever watering is necessary, the cost 
of four cents per square yard for the 
entire season should be ample. A cart 
fitted with the calcide process will treat 
nineteen thousand square yards a day, 
and average three hundred and eighty 
thousand square yards per month, car- 
ing for that area regularly. Calcide has 
no odor, is stainless, and has no harm- 
ful effects on horses’ feet, leather, or 
rubber tires. A road treated with cal- 
cide wears well and has a very pleasing 
color. 
Oil treatment in the Buffalo Park 
roads consisted of sprinkling with ordi- 
nary water sprinklers, using Standard 
Oil Company’s pail oil No. 875, to a 
width of about thirty feet. To sprinkle 
2,575 lineal feet of roadway thirty feet 
wide 1,274 gallons of oil were required, 
which, at six cents a gallon, cost $76.44; 
the cost of labor and teaming was $12; 
or a total cost of $86.44 for the treatment 
of 8,583 square yards, or at the rate of 
about one cent a square yard. 
The demonstration by The Wads- 
worth Stone & Paving Company, of 
Pittsburg, of their Kentucky Rock As- 
phalt as a binding and surfacing ma- 
terial for a macadam road was made on 
the state road just east of Williams- 
ville. The crown of the original ma- 
cadam road had been worn away and 
the surface left nearly flat. This old 
surface was loosened by being picked by 
a steam roller for a distance of about 
500 feet in length and 16 feet wide (the 
width of the original macadam). On 
this loosened surface was spread crushed 
limestone, in size from one and one- 
half inches to two and one-half inches 
in their longest dimensions. These 
coarse stones were spread about four 
inches thick in the center of the road 
and thinner towards the edges, until 
there was barely a single layer of new 
stone at the shoulder. By this method 
of spreading a crown was given the 
road of about one-half (j4) inch to the 
foot. This layer of stone was firmly 
rolled by a steam roller, in the same 
manner as usual in ordinary macadam 
road construction. 
Owing to the richness in asphalt of 
the product of the Wadsworth mines 
and the consequent adhesiveness of the 
material, it was found advantageous to 
repulverize the material as it was used. 
This was accomplished by putting it 
through a small disintegrator driven by 
a two-horse power gasoline engine. 
From the disintegrator the material was 
wheeled to the road and immediately 
spread with an ordinary steel garden 
rake. 
The asphalt was applied to the road 
in two layers and in the following man- 
ner : The first layer was spread on the 
firmly-rolled surface of two and one- 
half-inch stone, about three-fourths of 
an inch thick, and raked uniformly over 
the entire surface of the road. After 
the first course of asphalt was spread, 
a layer of one-inch crushed stone was 
spread as evenly as possible on the 
asphalt, and then rolled ; the one-inch 
stone serving to force the asphalt into 
the voids of the two and one-half inch 
stone below, thus making a secure bond. 
After rolling, the second layer of 
asphalt, about three-fourths of an inch 
thick, was applied and rolled, and the 
section of road was immediately opened 
to traffic. The demonstration covered 
a section of road 450 feet in length and 
16 feet wide, a total of 800 square yards. 
The crushed stone for resurfacing the 
road and the steam roller was furnished 
by the state, and the spreading and roll- 
ing of the stone was done under the 
direction of Mr. Frank L. Cohen, con- 
tractor for state road repairs in Erie 
County, New York. 
On surfacing the 800 square yards of 
road, 63,200 pounds of rock asphalt was 
used, at a cost of $259.43, f. o. b. car at 
Williamsville. The total cost of ma- 
terial and treatment was $357.43. 
Owing to the demonstration being a 
very small job, requiring but two days 
to complete, the cost per square yard is 
excessive, owing to the fact that the 
cost of preparation for doing this small 
job was just the same as would be nec- 
essary to prepare for the surfacing of a 
mile or more of road. Again, the men 
employed were entirely unfamiliar with 
the material and methods of applica- 
tion, and could hardly be expected to 
get accustomed to it in two days. 
The result of the demonstration is a 
smooth and permanently dustless piece 
of road, costing from twenty per cent 
to thirty-five per cent more than ordi- 
nary macadam, and, in addition to being 
dustless and mudless, should sustain an 
equal amount of traffic at least 100 per 
cent longer. The Asphaltoilene treat- 
ment was by The Good Roads Improve- 
ment Company, of Cincinnati, 0. Seven 
thousand lineal feet of Main street road, 
in Section No. 3, sixteen feet width of 
macadam, were treated with asphalt- 
oilene, which was applied by use of a 
sprinkler, especially made for the pur- 
pose. The approximate cost of this 
work was as follows : 
4,800 gals, asphaltoilene at 6c. .. .$388.00 
Freight, etc 68.00 
Labor, teams, etc 95.00 
Miscellaneous 84.00 
Total $535.00 
or about four and one-fourth cents per 
square yard.
