Methodology for Modeling the Uncertainty of Material Properties in Asphalt Pavements
Journal of Materials in Civil Engineering, 2014Most current modeling techniques assume that pavement layers are homogeneous. This assumption can be considered one of the main sources of uncertainty in the performance of pavement structures. The main objective of this paper is to present a methodology that includes the uncertainty of material properties as part of the mechanical response of pavement

Modeling of Moisture Loss in Cementitiously Stabilized Pavement Materials
International Journal of Geomechanics, 2005The paper presents a theoretical and experimental approach for the modeling of moisture loss during the drying of cementitiously stabilized pavement materials containing varying contents of fine-grained soil. The process of moisture loss was characterized by the isotropic nonlinear diffusion theory.

Modelling of salt migration in stabilised pavement materials
2005This paper presents the results of a laboratory study undertaken to model the salt migration in cementitiously stabilised pavement materials. The experimental method involves the simulation of capillary rise in cylindrical specimens close to 300 mm in height with salt solutions located at the specimen bases.

The design model of unbound granular materials for flexible pavement
Australian Journal of Civil Engineering, 2012This study aims to introduce an alternative design model of unbound granular base course materials by utilising laboratory test results such as resilient modulus, permanent deformation and bearing capacity of base course materials. Current pavement designs mostly overlook all problematical behaviours of unbound granular base layers and consider only as

Mechanical Characterization of Pavement Granular Materials Using Hardening Soil Model
International Journal of Geomechanics, 2018Various testing methods, such as the static triaxial test, cyclic resilient modulus test, repeated-load static triaxial test, repeated-load California Bearing Ratio (CBR) test, and repeated-load oedometer test, were explored to characterize pavement granular materials.

Fabrication of cooling asphalt pavement by novel material and its thermodynamics model
Construction and Building Materials, 2021Abstract It is an important research field to restrict the extreme temperature of pavement by using the robust thermal performance of phase change materials. In this study, diatomite, expanded perlite, and stearic acid were chosen to prepare compound phase change materials (CPCMs) for the fabrication of novel cooling asphalt pavement.

Modeling and Laboratory Assessment of Capillary Rise in Stabilized Pavement Materials
Transportation Research Record: Journal of the Transportation Research Board, 2004Capillary rise tests were carried out on marginal material (scoria) stabilized with two cementitious additives, general purpose cement, and general blended cement up to 5.5% by dry weight. The test results indicated that capillary rise occurred along the entire specimen height of 345 mm (100%) for both specimens.

International Journal of Geomechanics, 2006
The constitutive modeling of cyclic plasticity of soils has made great progress, especially in the area of sands liquefaction modeling. Nowadays, the problem of rutting of flexible pavements linked to permanent deformations occurring in the unbound layers is taken into account only by empirical formulas.
