Relationship between deformation moduli obtained using light falling weight deflectometer and static plate test on various types of soil

DOI: 10.3846/bjrbe.2014.31
 
There is increasing effort to optimize test methods for evaluation of subgrade. It takes effect in aspiration in replacement of static plate loading test by other faster test methods. One of them is the use of Light Falling Weight Deflectometer. In many countries in Europe both static and dynamic plate tests are standardized. The presented paper introduces results of the research project dealing with the sensitivity of the relationship between static modulus and modulus obtained from the Light Falling Weight Deflectometer on specific types of soil. It is shown that there are significant differences in relationship between moduli values obtained using both methods on different types of soil.
 
Keywords: deformation moduli, soil moduli, Falling Weight Deflectometer (FWD), Light Falling Weight Deflectometer (LFWD), static plate tests, moduli relationship.
