Characterization of permanent deformation properties of densely-compacted unbound granular materials subjected to cyclic loading [PDF]
Scientific Reports, 2023 To investigate the long-term deformation properties of unbound granular materials (UGM) that are ordinarily adopted to construct subgrade for high-speed railway, a series of medium-sized cyclic triaxial tests were performed to obtain the relationship ...

Pavement Analysis with the Consideration of Unbound Granular Material Nonlinearity
Designs, 2023 Accurate pavement design and evaluation requires the execution of response analysis. Pavement materials’ behavior does not necessarily conform to the assumptions of the multi-linear elastic theory usually adopted during pavement analysis.

Resilient behavior of unbound granular material: A review
Journal of Road EngineeringWhen a vehicle moves over a flexible pavement structure, it generates loading and unloading cycles that produce recoverable (resilient) and permanent (plastic) deformations in the granular base and subbase layers, which are made of unbound granular ...

Shakedown of unbound granular material [PDF]
Granular Matter, 2005 Compacted unbound granular materials are extensively used as sub-layer in pavement design. Most pavement design guides assume that they are responsible for the degradation and deformation of the roads and railways that they support. Biaxial tests are usually employed to investigate the elasto-plastic response of these materials to cyclic loading.
