They include a number of processed materials plus soil typesdefined according to the Unified Soil Classification System in ASTM D2487,“Standard Method for Classification of Soils for Engineering Purposes.”Table 7 provides recommendations on the installation and use based onclass of soil or aggregates and location within the trench. It is important toengineer all materials used in the pipe trench to work together and with thenative material surrounding the trench.44 EAGLE CORR PE INSTALLATION GUIDE
Figure 294.8.1 CLASS IA MATERIALSClass IA materials provide the maximum stability and pipe support for agiven density because of the angular interlocking of the material particles.With minimum efforts, these materials can be installed at relatively high densitiesover a wide range of moisture contents. These materials also haveexcellent drainage characteristics that may aid in the control of water. Thesesoils are often desirable as embedment in rock cuts where water is frequentlyencountered. On the other hand, when ground water flow is anticipated,consideration should be given to potential migration of fines fromadjacent materials into the open graded Class IA materials.4.8.2 CLASS IB MATERIALSThese materials are produced by mixing Class IA and natural or processedsands to produce a particle-size distribution that minimizes migration fromsurrounding soils that may contain fines. They are more widely graded thanClass IA and thus require more compaction effort to achieve the minimumdensity specified. When these materials are properly compacted, these soilsexhibit high stiffness and strength, and depending on the amount of fines,may be relatively free draining.4.8.3 CLASS II MATERIALSEAGLE CORR PE INSTALLATION GUIDE45
