Before compacted soil ruins are open to the public,they need to be restored and reinforced.Usually,a synthetic resin (polyurethane resin) is used to reinforcement the ruin's body and surface.However,there are a series of problems when the synthetic resin is used,such as the decrease in the soil's strength and the damage to the ruin's structure.This paper shows an attempt of using slake lime,glutinous rice cooking soup and tung oils to reinforce ruins constructed of Masa and Volcanic soils which are widely distributed in Kyushu Japan.The unconfined compression,odeometer,drying and wetting durability and freezing and thawing durability tests were carried out on samples prepared with different patterns.Tests results show that addition of 4% tung oils and slake lime into the samples could dramatically increase the strength of compacted soils.Samples have good compressibility and freezing and thawing durability.In particular,the drying and wetting durability is reinforced.The method could be applied in restoration projects on fill ruins located in Kyushu area,Japan.
