Reinforcement of aggregate base course confined by cubic structure of geotextiles.

摘要

Methods of reinforcing the aggregate base course confined by the cubic structure of geotextiles are presented, to reduce the settlement of aggregates by improving the rigidity of aggregate base course. An aggregate base course using geotextiles wasreinforced by placing the geotextiles between the subgrade soil and aggregate layer. The placing method was compared with the cubic structure method experimentally. The settlement occurring at the centre of the loaded portion of the aggregate surface confined by the cubic structure of geotextiles was smaller than that of the conventional methods. Parameter ut/us expressed the bearing effect of the base course, specifically the rigidity of the aggregate layer. The result of the bearing effect of the basecourse was obtained in the case of combining the conventional method with the cubic structure method.
