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

本研究的目的是通过实验和使用SYS Cam-clay模型的计算来了解“ICIER”和造纸污泥灰（PS-ash）改良土壤的力学行为，新发现如下：（1）Elasto -“IURA”机械行为的塑性解释，一种陶瓷副产品及其用石灰改良的土壤 RDA 的行为类似于中密砂的行为，“ICIItA 的行为类似于沙子之间的土壤”和粘土的弹塑性参数和土壤骨架结构的退化。（2）PS（纸污泥）闪光改良土壤力学行为的弹塑性解释1）27％PS灰改善的'ICIER (P527)，含水量最佳，无侧限抗压强度超过200kPa，是未改良‘KIRA’的8倍，改良后的土壤仍具有高保水性沙子和粘土之间。 2）用聚苯乙烯灰代替水泥的新型路面材料，28天强度仍达到2000kPa以上，并具有一定的保水能力。 3)通过使用SYS Cam-clay模型计算，PS27表现为重度超固结和高度结构化的土壤，具有缓慢的结构衰减和缓慢的超固结损失。(3)创建一种新型保水和透水路面材料一种新型路面材料是由将 KIRA 与 PS-灰、水泥和骨料混合。通过无侧限压缩试验，强度比PS27大。峰值强度时的轴向应变约为 1%，这意味着该行为表现出脆性。保水性高于一般沙子的保水性。这些材料能够提供保水和透水的路面材料
