To promote co-operation and exchange of information about the behaviour of soil particles (clays to gravels) and the interactions amoung themselves and with pore fluids (air, water and other liquids). 

To clarify the fundamental micro-mechanisms of macroscopic soil behavior.

1.To encourage microscopic particle-scale understanding of significant macroscopic behaviours of gravel, sand, clay and their mixtures, such as compressibility, anisotropy, yielding, creep, cyclic liquefaction, shear failure and tensile fracture.

2.To promote discussions on the use of micro-scale measurements and simulations to enhance soil characterisation procedures (grading, plasticity index, CPT / SPT etc) and to clarify the selection and use of continuum parameters in geotechnical engineering practice.

3.To promote better practice of Discrete Element Modelling (DEM) of soil aggregates, through simulations of laboratory tests and round-robin tests.

Encourage preparation of keynote lectures, state-of-the-art lectures including new technology, round robin tests, blogs, general reports for conferences organized by the International Society, regional conferences and conferences organized by Member societies.

Interact with industry and overlapping organizations working in areas related to the TCs specialist area: - ASCE Granular Materials committee - ALERT (Europe) - GM3 (UK) - National research group - Korean Geotechnical Society - National research group - Chinese Geotechnical Society - National research group - Japanese Geotechnical Society
