Permanent Deformation Behaviour of Unbound Granular Materials in Pavement Constructions
… the risk level of permanent deformations in the unbound granular layers (UGL) in pavement constructions under consideration of the seasonal effects. From this data a serviceability limit line (plastic shakedown limit) stress boundary for the unbound granular materials (UGM) was defined for …

Permanent deformation behavior of unbound granular materials and rutting model development
… was found to produce inadequate rut estimates in unbound aggregate base/subbase layers by discounting the contribution of stress state from the original Tseng and Lytton (1989) model. This research study was aimed at developing a new permanent deformation prediction model that would properly take …

Characterization of Anisotropic Granular Layer Behavior in Flexible Pavements
… the cross-anisotropic material properties of unbound granular materials from triaxial repeated load testing with using UI-FastCell which has custom designed for testing unbound granular materials with unique capabilities. The cross-anisotropic behaviors of different granular materials were …

Validation of FWD Testing Results at the Virginia Smart Road: Theoretically and by Instrument Responses
… 1) to determine the resilient moduli of the unbound granular materials on the Virginia Smart Road using small and large plates of the FWD; 2) to investigate the extent of spatial and temporal variability of the FWD deflections among pavement sections; 3) to develop a temperature correction …

Three-Dimensional Finite Element Analysis of Flexible Pavements Considering Nonlinear Pavement Foundation Behavior
… deformation behavior of pavement foundation geomaterials, i.e., fine-grained subgrade soils and unbound aggregates used in untreated base/subbase layers, due to repeated wheel loading. This nonlinear behavior is commonly characterized by stress dependent resilient modulus material models that …

Quantifying Workability, Compactability, and Cohesion Gain of Asphalt Emulsion Cold In-Place Recycling
… of asphalt emulsion cold recycled materials, along with factors which influence characterization, pertaining to the measurement of workability, compactability, and cohesion gain. In Chapter 2, a detailed review of the progression of mix design procedures for unbound granular …
