The objective of this study is to comprehend the mechanical behavior of 'ICIER and the soil improved by paper sludge ash(PS-ash)through the experiment and the computation using SYS Cam-clay model The new findings are as follows ;(1) Elasto-plastic interpretation of mechanical behavior of 'IURA,' a ceramic by-product and its soil improved with lime The behavior of RDA is similar to the one of medium dense sand, and 'ICIItA behaves as the'soil between sand and clay in elasto-plastic parameters and the degradation of the soil skeleton structure.(2) Elasto-plastic interpretation of mechanical behavior of the soil improved with PS (Paper sludge) ?ash 1)The 'ICIER improved by PS ash of 27% (P527),of which water content is optimum, has unconfined compression strength of more than 200 kPa, that is 8 times unimproved 'KIRA' The improved soil still has high water retention between sand and clay. 2)The new pavement material using PS-ash instead of cement still has 28-day strength of more than 2000 kPa and has water retention capacity to a certain extent. 3)PS27 behaves as heavily overconsolidated and highly structured soil with slow structure decay and slow overconsolidation loss through the computation using SYS Cam-clay model.(3) Creation of a new water-retentive and permeable pavement material A new pavement material was created by mixing KIRA with PS-ash, cement and aggregate. Through unconfined compression test, the strength is larger than the one of PS27. The axial strain is about 1 % at the peak strength, which implies that the behavior shows brittle. The water retention is higher than the one of typical sand. These materials are able to provide a water-retentive and permeable pavement material

The objective of this study is to comprehend the mechanical behavior of 'ICIER and the soil improved by paper sludge ash(PS-ash)through the experiment and the computation using SYS Cam-clay model The new findings are as follows ;(1) Elasto-plastic interpretation of mechanical behavior of 'IURA,' a ceramic by-product and its soil improved with lime The behavior of RDA is similar to the one of medium dense sand, and 'ICIItA在弹性塑料参数和土壤骨架结构的降解中的沙子和粘土之间的行为。 “ Kira”改良的土壤在沙子和粘土之间仍然具有很高的水分。 2）使用PS-Ash而不是水泥的新的路面材料仍然具有2000 kPa的28天强度，并且在一定程度上具有保留水分的能力。 3）PS27的行为是通过使用SYS CAM-CALE模型通过计算来实现较慢的结构衰减和缓慢的结构性损失的严重过度固结和高度结构化的污垢。（3）创建一种新的保水且可渗透的路面材料，将新的路面材料与Ps-Ash，sas-ash，ass-ash，scement and cement，scement and cement和cotchegration混合在一起。通过无限制的压缩测试，强度大于PS27中的强度。轴向应变在峰值强度下约为1％，这意味着行为显示脆性。保留水比典型的沙子高。这些材料能够提供水含水和可渗透的路面材料
