BITUMINOUS RESURFACING. 
LEE County, Fort Myers, FLtA.—Work was begun resurfacing the McGregor 
Boulevard leading from Fort Myers toward Punta Rassa on April 29, 1914, and 
completed May 7, 1914. The road was built with shell and given a bituminous 
surface treatment in the fall of 1912 under the supervision of this office.* 
From the time of the construction in 1912 to the resurfacing in May, 1914, the 
road was practically without maintenance or repair. 
The surface was prepared by sweeping it clean with a street sweeper and 
hand brooms, and the grass was scraped from the roadsides with a grader. 
The oil was hauled an average of 24 miles and applied from a 500-gallon 
gravity distributor to the hard, dry, clean surface. It was allowed to stand 
until absorbed, and then covered with a thin coat of sand. One-half of the 
road was treated at a time in order to allow traffic the uninterrupted use of 
the road. The average rate of application was 0.246 gallon per square yard. 
The sand, obtained from the roadside, was screened, and spread to a depth of 
about three-sixteenths of an inch. 
The road was treated for a width of 16 feet and a length of 8,950 feet, or an 
area of 15,911 square yards. Labor was $1.80 per day, and teams $5 per day 
of nine hours. Oil cost $0.0575 per gallon f. o. b. tank cars at Fort Myers. 
The total cost of the work was $478.51, which is at the rate of $282 per mile, 
or $0.0301 per square yard. The principal items of cost were preparing sur- 
face, $0.0029 per square yard; cost of oil, $0.0142 per square yard; hauling and 
applying, $0.0018 per square yard; brooming, $0.0018 per square yard; excavat- 
ing and screening sand, $0.0088 per square yard; and spreading sand, $0.0011 
per square yard.
