West RUTLAND, VT.—Work was begun September 20, 1913, on a gravel road 
starting 34 miles west of West Rutland and extending toward Castleton. It 
was completed October 8, 1913, with a loss of two days on account of rain. 
The adjacent land is hilly and the natural soil is sandy loam. 
The road was graded 26 feet wide in both cuts and fills for a distance of 528 
feet. The maximum cut was 2 feet, the maximum fill 1.8 feet, and the maxi- 
mum grade of 4 per cent on the old road was reduced to 3 per cent on the 
new road. <A surface of bank gravel 21 feet wide was laid, making a sur- 
faced area of 1,282 square yards. 
One 8 by 3 foot masonry culvert was lengthened. 
The total cost of the work, including culvert, was $265.83, or $0.215 per 
square yard. 
EXPERIMENTAL ROAD WORK. 
A portion of the special appropriation for experimental road im- 
provement was used to resurface with limestone macadam the road 
known as the Rockville Pike, in Montgomery County, Md., and to 
then treat the surface with various bituminous materials in con- 
junction with gravel, trap-rock screenings, and limestone screenings. 
The resurfacing was begun March 15, 1913, and the surface treat- 
ment started on September 5, 1918. The work was completed and 
the road opened to the public on December 17, 1913. In addition to 
the Rockville Pike, a 1,500-foot section on Bradley Lane, east from 
the pike, was resurfaced with limestone. The land adjacent to the 
road is rolling and the natural soil is for the most part a mica clay. 
The reports following describe the resurfacing as done under the 
four contracts into which the work was divided. For a detailed 
description of the bituminous surface treatments, which were car- 
ried out in seven distinct sections, see Department Bulletin No. 105, 
“Progress Report of Experiments in Dust Prevention and Road 
Preservation, 1913.” 
LIMESTONE MACADAM RESURFACING. 
Contract No. 1, RocKVILLE PIKE, Mp.—Work was begun March 15, 1918, on 
the road from station 61+20 to station 210 and was completed August 8, 1913, 
with a loss of eight days on account of bad weather. The old roadbed was 
loosened by spikes in the roller wheels and a 3-ton scarifier. 
The old macadam was reshaped and a surface of macadam was laid for 
14,460 feet, 15 feet wide, making 24,100 square yards. About 248.22 tons of 
No. 1 stone were used to fill depressions, after which 2.911.75 tons of No. 2 
stone were spread 3 inches deep before compacted, and 1,164.31 tons of stone 
screenings used for a binder course. The stone was shipped on the ears and 
the haul from the cars to the road was 1% miles. 
Ditches were dug to the extent of 20,923 linear feet. 
The equipment consisted of three 10-ton steam rollers, one sprinkler wagon, 
grading machine, dump wagons, gasoline pumps, tanks, small tools, ete. 
The road was built by contract for $11,638.14, which is at the rate of $0.483 
per square yard. Labor cost $1.70 and teams $4.50 per day of eight hours.
