A New Granulation Method with the Process of Crumbling Partially-cemented Liquid Muds and its Application to a Motocross Track

A new method for granulating liquid muds was proposed. This method involves the crumbling of partially cemented muds. The crumbling is the re-stirring of the cement-mud mixture when certain time elapsed after the cement was added to the liquid muds. Laboratory experiments revealed that the cone indices of the cement-mud mixtures measured after they are primary cured can be used to control the possibility of granulation and the particle size of granules obtained. The test results also indicate that the granules show high potential for use in materials such as reclamation, subgrade or backfill materials. The application of this crumbling granulation method in the maintenance work of a motocross track was also presented in this study.
