equipment for a rather large project in a community where few other 
concrete roads are likely to be constructed. 
The equipment necessary for handling and hauling the materials 
frequently represents a much greater outlay of capital than all other 
expenditures combined, but, as has already been pointed out in dis- 
cussing the handling of materials, the conditions affecting this fea- 
ture of the work are subject to great variation. A general discussion 
as to the cost of this part of the equipment, therefore, would usually 
be of small value in connection with any particular project and will 
not be undertaken. 
The equipment necessary for doing the rough grading in connec- 
tion with concrete road work is not essentially different from that 
required for grading other types of roads. Since the amount of cap- 
ital necessary to provide grading equipment to suit various sets of 
conditions is familiar knowledge to practically all road engineers 
and contractors, this feature will' not be discussed here. 
The capital required to provide equipment for preparing the sub- 
grade and mixing and placing the concrete depends on the rate at 
which it is purposed to carry on the work. The lists given below 
show the approximate cost of outfits using either a 2-bag or a 3-bag 
mixer.

1,800 feet of steel forms, complete with stakes, etc 200 
1 pump ami engine capable of delivering at least 1,500 gal- 
lons of water per hour 175
