Resilient behavior of unbound granular material: A review

open access: yesJournal of Road Engineering
When 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 ...

Pavement Analysis with the Consideration of Unbound Granular Material Nonlinearity

open access: yesDesigns, 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.

Shakedown of unbound granular material [PDF]

open access: yesGranular 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.

Requirements for Pavement Base Layers with Unbound Granular Material [PDF]

open access: yesSlovak Journal of Civil Engineering, 2019
Pavement structures, layers, and parameters must meet the strict requirements of applicable standards and regulations. The thickness of layers and the choice of materials depend on the factors involved, i.e., the traffic load and climatic factors ...

Investigation on permanent deformation of unbound granular material base for permeable pavement: Laboratory and field study

open access: yesInternational Journal of Transportation Science and Technology, 2023
Unbound Granular Materials (UGM) base is widely used in permeable pavement structure for infiltration, water storage, and load bearing. However, because of large void content, UGM base easily deforms under repeated loads, resulting in surface rutting and

Long life pavements with recycled concrete in unbound granular layers

open access: yesRoads and Bridges, 2023
The construction of unbound granular layers (UGLs) in pavement construction is mainly based on empiric knowledge of the behaviour of natural aggregates. Is it possible to transfer this behaviour to the performance of recycled materials in UGLs?

Determination of permanent deformation of flexible pavements using finite element model

open access: yesGrađevinar, 2022
The unbound granular material used in flexible road pavements exhibits an elastoplastic behaviour under repetitive traffic loads. Permanent deformation occurring on pavement surface under traffic load is one of the main road pavement problems affecting ...
