Stabilisation with geogrids for transport applications – selected issues [PDF]
MATEC Web of Conferences, 2019 Stabilisation is defined as improvement of the mechanical properties of an unbound granular material by including one or more geosynthetic layers such that the deformation under applied loads is reduced by minimizing soil particle movement. Paper discuss

Resilient Behaviour of non Standard Unbound Granular Materials [PDF]
Road Materials and Pavement Design, 2009 The results of experimental work on three non-standard granular materials used in road construction are presented. Small strain precision triaxial tests under cyclic loading and wetting tests were performed on all samples. The materials' state parameters studied included: Los Angeles abrasion coefficient, Plasticity Index, and fines content above ...

Modelling the permanent deformation of unbound granular materials in pavements
Road Materials and Pavement Design, 2022 An existing permanent deformation (PD) model for the unbound granular materials (UGMs) in pavements, developed based on multistage (MS) repeated load triaxial (RLT) tests, was modified to better suit to field conditions and software applications. The model was calibrated for a few UGMs with a series of moisture contents (w) using MS (to include the ...

Behavior of unbound granular materials—part I: isotropic case [PDF]
Computers and Geotechnics, 2003 The paper discusses the modeling of the behavior of unbound granular materials. A representative approach that highlights some salient features of the behavior is proposed. This approach is essentially based on experimental results and the study is extended to the construction of the elastic potential from test results. to complete the analysis, two no-

Two unbound granular materials stiffness analysis with staged repeated load CBR test [PDF]
MATEC Web of Conferences, 2019 Design methods of flexible pavements in many countries are based on linear elastic behaviour model for Unbound Granular Materials (UGM). In this context, parameters required to characterize an UGM in structural analysis of pavements are Stiffness modulus
