ABSTRACT
In Toyama Prefecture of Japan, which has abundant nature, the primary industry is thriving, but a lot of waste-based biomass is generated in the manufacturing process, and we are having a hard time disposing of it. Therefore, the authors wondered if these and Masa soil could be mixed and used as a ground material. In this study, compaction test, CBR test, and repeated triaxial compression test were conducted to examine whether biomass mixed soil can be applied to simple pavement. In all the samples conducted in this study, CBR was 3% or more, so it was found that they can be generally used not only for simple pavement and pedestrian pavement but also for roadbed materials. In addition, as a result of repeated non-drainage triaxial tests using biomass-mixed Masa soil, the liquefaction strength increased when 10% of crab and bamboo powder were mixed.
