The cost of hauling and piling on the side of the street is about $1.00 per thousand for a haul of 1 mile, of which sum about half is the cost of loading and unloading and half the cost of team and driver; but this cost for team and driver necessitates the use of three wagons with each team.
The number of bricks that a man can set in a day varies with the size of the bricks or the blocks. An average laborer, excluSive of preparing the surface, can set 10,000 to 12,000 small brick in 10 hours; and an expert will set 15,000 in 10 hours. " Under unfavorable circumstances nine men in 13 hours prepared the sand bed, set the brick, and completed the pavement at the rate of 3,160 bricks per hour per man." * An ordinary laborer can set 8,000 or 10,000 3" X 4" X 9" blocks in 10 hours, and a good man will set 10,000 to 12,000.
The organization of a paving gang is usually about as follows: This gang should lay at least 1,000 square yards in 10 hours, and under very favorable conditions should lay 1,200 square yards. The cost then of laying, including preparing the sand bed, setting the blocks, and filling the joints with sand, and including also general superintendence, is from 21 to 3i cents per square yard. If the brick blocks are piled upon the side of the street, one and possibly two more men will be required to deliver the blocks, de pending upon the height and condition of the surface upon which the bricks are piled; and the cost of laying will therefore be in creased 2 or 3 cents per square yard. Not infrequently the total cost of laying the brick is 8 or 9 cents per square yard; but this excessive cost is due to poor management.
In a particular case, 80 hours were required to turn the chipped blocks and to replace the rejected blocks with good ones, in 1,633 square yards of pavement, or, say, 1 hour for each 20 square yards. The blocks were 3" X 4" X 9", and about 2 per cent were turned and about 2 per cent were rejected.
The cost of filling the joints of a brick pavement is about as follows: with sand, 2 cents per square yard (§ 774); with tar, 10 to 12 cents (§ 775), and with Portland-cement grout mixed in small quantities and dipped upon the pavement, 10 to 12 cents per square yard (§ 777), and with uniform brick and care in getting thin joints may be only 9 or 10 cents.
The expansion joints will require a gallon of tar for each 5 or square yards of pavement at a cost of, say, 8 cents per gallon, or cent per square yard of pavement.
A summary of the preceding data on the cost of brick pave ments is as follows: If the joints are to be filled with Portland-cement grout 1 to 1 in the best manner (see § 777), add 10 cents per square yard to the above for the grout filling, and 1i cents per square yard for the expansion joints.
The average cost of 17,000 square yards of brick pave ment constructed by the City of Minneapolis, Minn., in 1897 by the city's force is given below.* The foundation consisted of 6 inches of concrete composed of 1 part natural cement, 2 parts sand, and 5 parts broken stone. The sand cushion was 1 inch thick. The bricks were re-pressed, and were made in Galesburg, Ill. They were 2i" X 4" X 8", and cost $15.54 per thousand, or 87 cents per square yard, f. o. b. cars Minneapolis. The joints were filled with a patent filler, under contract with the patentee. Half-ineh expansion joints were inserted across the street about 150 feet The cost of brick pavements vary greatly with the lo cality, chiefly owing to the difference in the cost of transportation; but in the states of Ohio, Indiana, Illinois, and Iowa, and the nearby portions of the adjoining states, the cost of a pavement composed of re-pressed bricks or blocks on a 6-inch concrete foundation generally ranges from $1.20 to $1.70 per square yard.* If no concrete is required for a foundation, the above prices may be reduced 48 or 55 cents per square yard.
