I.D.I.D.MinimumspacingFigure 325.0 Minimum and maximum BURIAL DEPTH RECOMMENDATIONS5.1 Burial DepthsMaximum and minimum burial depths are determined by the type of initialbackfill material and compaction level (assuming a suitable foundationand bedding). Assuming the plans meet the initial backfill and compactionrequirement of Table 7 the construction plans should take precedence.Any discrepancies should be brought to the attention of the design engineer.5.1.1 Minimum CoverIn addition to the minimum cover height requirements, an extra foot oftemporary cover is recommended where heavy-duty construction equipmentmay travel over the pipe during the construction phase of the project.For H-25 traffic loads, a minimum cover of 12 inches, measured from thetop of the pipe to the top of rigid pavement sections or the bottom of flexiblepavement sections, is recommended for pipe diameters 48 inches and less.For H-25 traffic loads, a minimum cover of 24 inches, measured from thetop of the pipe to the top of rigid road surfaces or the bottom of flexibleroad surfaces, is recommended for 60-inch pipe. See Table 10 for details.Minimum covers may be reduced in areas with no or infrequent light traffic,provided flotation is not a concern and the design has been reviewed byan engineer.EAGLE CORR PE INSTALLATION GUIDE51
