Viscous Behaviour of Unbound Granular Materials in Direct Shear

Soils and Foundations, 2008
ABSTRACT The viscous properties of a variety of poorly graded unbound granular materials were investigated by direct shear tests on 12 cm-cubic specimens. A number of natural sands having different particle shapes and sizes as well as uniform glass beads having different particle sizes were used.

Preparation, Characterization and Modeling of Unbound Granular Materials for Road Foundations

Applied Sciences, 2018
A wide range of granular soils were laboratory prepared as base and sub-base materials in flexible pavements technology. The samples were produced according to the requirements defined in the Spanish General Technical Specifications for Roads and Bridge ...

Neural network-based model for prediction of permanent deformation of unbound granular materials

Journal of Rock Mechanics and Geotechnical Engineering, 2019
Several available mechanistic-empirical pavement design methods fail to include predictive model for permanent deformation (PD) of unbound granular materials (UGMs), which make these methods more conservative.

Resilient modulus for unbound granular materials and subgrade soils in Egypt

MATEC Web of Conferences, 2017
Mechanistic Empirical (ME) pavement design methods started to gain attention especially the last couple of years in Egypt and the Middle East. One of the challenges facing the spread of these methods in Egypt is lack of advanced properties of local soil ...

Dataset of mechanical properties of coarse aggregates stabilized with traditional and nontraditional additives: Stiffness, deformation, resistance to freezing and stripping

Data in Brief, 2023
The dataset derives from a thorough laboratory characterization of all existing stabilization technologies suitable for coarse-graded aggregates. They include two traditional binders (based on cement and bitumen) and eleven nontraditional binders (based ...

Influence of Laboratory Compaction Method on Compaction and Strength Characteristics of Unbound and Cement-Bound Mixtures

Applied Sciences, 2021
During road construction, granular materials for the unbound base course (UBC) and cement-bound base course (CBC) are mostly compacted by vibratory rollers.
