DEFINITION OF WORKABILITY FOR DIFFERENT SOILS

DEFINITION AV BEARBETBARHET FOER OLIKA JORDAR

In the present report the soil material properties essentially influencing the capacity of the machinery for earth removal are defined. Furthermore the report contains recommendations for a systematized and constructional adjusted working procedure for evaluation and description of results obtained. Workability is determined by evaluation of soil excavation ability and bearing capacity. By soil excavation ability is meant the soil properties influencing earthwork capacity. The soil excavation ability is determined by the soil resistance to excavation and the influence of soil on the shovel content. By bearing capacity is meant the ability of the soil to bear the working equipment. Soil water sensitivity and the variation of water content can influence the bearing capacity. The bearing capacity is classified for the measured and for the expected minimum and maximum water content in the soil regarding topography and hydrology. Comprehensive testing activities carried out on projects indicate no single test method for establishing excavation ability and bearing capacity. The investigation proves that standard test methods can be used for classification of workability. /TRRL/
