Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a reforming method for water-containing fine-grained soil capable of reforming the water-containing fine-grained soil to soil reusable for diverse aims by improving the CBR strength and water permeability while being granulated. SOLUTION: The water-containing fine-grained soil of the slump value of 4-10 cm is mixed with a liquid carboxyl group containing water soluble polymer and a mixed auxiliary material comprising crushed stones of the grain size of 25-40 mm, gravels, or the like. A solidifier such as lime is added thereto to be gravitationally mixed by a rolling drum and cured. COPYRIGHT: (C)2005,JPO&NCIPI
