2、Standard Specification for Reinforced Concrete Culvert, Storm Drain, and Sewer Pipe Metric AASHTO Designation: M 170M-151ASTM Designation: C76M-14 1. SCOPE 1.1. This specification covers reinforced concrete pipe intended to be used for the conveyance of sewage, industrial wastes, and storm water, an

3、d for the construction of culverts. 1.2. This specification is the metric counterpart of M 170. Note 1This specification is a manufacturing and purchase specification only, and does not include requirements for bedding, backfill, or the relationship between field load condition and the strength clas

4、sification of pipe. However, experience has shown that the successful performance of this product depends upon the proper selection of the class of pipe, type of bedding and backfill, controlled manufacture in the plant, and care that installation conforms to the construction specifications. Owners

5、of the reinforced concrete pipe specified herein are cautioned that they must correlate the field requirements with the class of pipe specified and provide inspection at the construction site. Note 2Attention is called to the specification for reinforced concrete D-load culvert, storm drain, and sew
