A. 
Concrete curb and concrete curb and gutters shall be constructed in accordance with the plans and specifications, at the required locations, and to the prescribed lines, grades, and dimensions.
B. 
The concrete shall be Class B and the work shall conform to the requirements specified in Article VII of this chapter.
C. 
Metal forms shall be used, unless otherwise approved by the Borough Engineer, and shall be lubricated with an approved material that will not cause stains. The concrete shall be tamped and spaded or vibrated so that the forms are completely filled, the concrete is thoroughly compacted, and mortar is flushed to the face and top. Before the concrete has taken its initial set, the top shall be finished with a wood float to an even, smooth, and dense surface. As soon as the forms can be removed, the face shall be finished in the same manner. Expansion joints 1/2 inch in thickness, shall be provided at intervals of 20 feet; and where the curb is adjacent to the concrete surface, a one-fourth-inch expansion joint shall be provided. The edges shall be neatly rounded to the radius required by the plans, and the finished work shall have a neat and workmanlike appearance.
