4、lude requirements for bedding, backfill, or therelationship between field load condition and the strength classification ofpipe. However, experience has shown that the successful performance ofthis product depends upon the proper selection of the class of pipe, typeof bedding and backfill, and care
5、that the installation conforms to theconstruction specifications. The owner of the reinforced concrete pipespecified herein is cautioned that he must correlate the field requirementswith the class of pipe specified and provide inspection at the constructionsite.2.
