Analysis of Applicability of Clegg Impact Soil Tester for Clayey Soils

Abstract

Dynamic test methods are used in numerous civil engineering sections. Evaluation of the earthwork quality can be carried out effectively using these methods. Equipment utilized the dynamic methods, such as Clegg Impact Soil Tester, is portable and usable in cramped areas or difficult accessible places. Another benefit is that these apparatuses can be used for quick controlling of the subsoil layers during the subsoil improvement. Clegg Impact Soil Tester can substitute the common test equipment in terms of the earthworks assessment. However, boundary conditions of apparatus given by the manufacturer need to be taken into account to obtain results with sufficient reliability. Method is based on the impact effect of the test equipment on the ground. Thus, results have to be interpreted carefully considering the type and the physical state of the tested soil.
