Outline of Final Research Achievements

Research results, 1) It was found that the water absorption effect of the bamboo chip changes with time and takes a constant value after 12 hours. 2) The strength of the bamboo chips mixed soil increases with increasing additive rate of bamboo chips, to satisfy the truck carrying strength. 3) Treatment soil in combination with bamboo chips and solidified material (cement) satisfies the required strength of embankment regardless of the shape of bamboo chip, soil sample and set water content ratio. In addition, it is also possible to reduce the amount of solidified material used for the bamboo chips mixed treated soil. 4) Bamboo chips mixed treated soil acts as a reinforcement bamboo fiber tensile, it becomes brittle fracture.5) Bamboo chips mixed treated soil is affected by decay is small.
