The Effect of Cyclic Load Characteristics on Unbound Granular Materials
Transportation Infrastructure Geotechnology, 2019Vertical load characteristics used in laboratory repeated load triaxial tests (RLTT) have a significant impact on evaluating unbound granular materials (UGMs) for the flexible road pavements. Many studies and standard testing protocols suggest a diverse range of these characteristics (i.e.

Implementation of shakedown and packing theories for unbound granular materials
2017Enhancing the load bearing quality of granular layers is fundamental to optimize the structural performance of the pavements. Unbound granular materials are one of the most used materials in the base layers of pavements. There have been growing interests on the behavior of unbound granular material in road base layers. Both design of a new pavement and

Hollow cylinder apparatus for testing unbound granular materials of pavements
Road Materials and Pavement Design, 2012Unbound granular materials used in pavement structures are subjected to a complex stress path which includes rotational stresses. Hollow cylinder apparatuses (HCAs) are suitable laboratory devices for reproducing stress paths found in the field. However, as the size of the HCA depends on the size of the granular particles, their use for testing unbound

Effect of loading frequencies on permanent deformation of unbound granular materials
International Journal of Pavement Engineering, 2019Unbound granular materials (UGMs) show both permanent and resilient deformations under repeated traffic loads.

Permanent deformation and resilient modulus of unbound granular materials
2018Permanent strain and resilient modulus provide direct, quantifiable values that describe two types of deformation (irrecoverable and recoverable) of pavement foundation materials under repeated transient traffic loads. Although the permanent deformation is not directly used in pavement design calculation, it affects the long-term performances of ...

Fundamental characterisation of the anisotropic resilient behaviour of unbound granular materials
International Journal of Pavement Engineering, 2019The paper presents an in-depth investigation of the resilient behaviour of an unbound base material. It is based on the assumption that the material is non-linear and cross anisotropic.

Some aspects of bounded and unbounded shear flows of granular material
1992Abstract The present paper examines some features of molecular dynamics type simulations of granular shear flows of smooth, inelastic, spherical particles between two relatively closely spaced rough walls. Profiles of granular temperature, solids fraction and mean velocity, and values of the wall slip velocities are determined for various mean solids
