This work was carried out in the framework of a larger project devoted to the micro-mechanical modeling of clayey soils by means of discrete element simulations. Here, we study the rheology and microstructure of granular media composed of platy particles. The particles are three-dimensional square plates, approximated as spheropolyhedra. Several samples composed of particles of different levels...

Dense granular materials behave differently from classical fluids or solids and can not be described through the continuum theories developed for those. In fact behavior at macro-scale is strongly related to smaller-scale field variables and kinetic processes. The influence of the micromechanics on the non-coaxiality of stress, strain and anisotropy of soils, is an essential part of a constitut...

Conventional flexible pavements built on lime stabilized soils (CFP-LSS) were studied for the backcalculation of pavement layer moduli from nondestructive Falling Weight Deflectometer (FWD) testing. The validated ILLI-PAVE finite element program was used in pavement structural analyses by taking into account the effects of nonlinear layer modulus behavior, i.e., stress hardening for granular ma...

This paper documents the successful application of explosive compaction technology for the densification of granular soils using case history data from a number of sites. The data include densification projects in urban areas, for dam foundations and for offshore structures. The paper provides general background information on the theory of explosive compaction of soils, design considerations, ...

The microplot experiment was carried out on two soils (clay and sandy) with spring wheat fodder pea. In the experiment, effect of a granular product made basalt dust elemental sulphur content 1.5% tested. Fertilization in dose 30 kg/ha S pea 20 form basalt-sulphur granulate resulted significant increase methionine, cystine protein grain sandy soil. However, no these amino acids seeds observed. ...
