1. See ASTM D 2321 or D2487 for detailed description and classificationof material.2. Also includes materials that begin with SW, SP, GW, GP and less than orequal to 12 percent fines.3. GM, GC, SM, SC or any soil beginning with one of these symbols containing> 12 percent passing #200 sieve; CL, ML or any soil beginning withone of these symbols with less than or equal to 12 percent retained on#200 sieve.4. Not recommended for pipe applications. Some Class IV material may beused under special circumstances and under the direct supervision of adesign or geotechnical engineer.5. Layers should not exceed half the pipe diameter. Layer heights may needto be reduced to accommodate compaction methods.As with the bedding, it is important to prevent the migration of soils. Themigration soil between bedding and initial backfill and between the initialbackfill can affect the structural integrity of the installed system. If differentmaterials are used or there is the potential for soil migration, precautionsuch as nonwoven geotextile layer, use of acceptable bedding material withfines that fill potential migration sites, or other acceptable method to avoidcompromising the trench backfill materials as specified by the engineershould be taken.4.7 Haunching42 EAGLE CORR PE INSTALLATION GUIDE
