BITUMINOUS RESURFACING. 



Lee County, Fort Myers, Fla. — 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. 1 

 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 2\ 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 S.950 feet, or an 

 area of 15,911 square yards. Labor was $1.S0 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, $0.0013 per square yard; brooming, $0.001S per square yard; excavat-
