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.

New shakedown criterion and permanent deformation properties of unbound granular materials

Journal of Modern Transportation, 2019
Unbound granular material specifications for road pavements in Australia are primarily based on physical material specification rather than mechanical characterisation.

Local Stiffness Assessment of Geogrid-Stabilized Unbound Aggregates in a Large-Scale Testbed

Applied Sciences, 2023
This paper integrates and extends an earlier article presented at the 20th International Conference on Soil Mechanics and Geotechnical Engineering. The generation of a stiffened zone in the proximity of a geogrid is one of the primary mechanisms of ...

Study of the Permanent Deformation of Soil Used in Flexible Pavement Design

Advances in Civil Engineering, 2020
The decreasing supply of soils with geotechnical parameters suitable for pavement designs is a visible problem in our environment. In order to establish more efficient designs and adequate construction criteria, it is essential to understand the ...

Laboratory investigation of soil-aggregate-cement mixture

Transportes, 2022
Cement stabilization improves physical and mechanical properties of geotechnical materials. However, numerous combinations of geotechnical materials and cement hinder to establish a pattern of mechanical behavior of cement-stabilized materials.

Impact of stabilisation on mechanical properties of recycled concrete aggregate mixed with waste tyre rubber as a pavement material

Case Studies in Construction Materials, 2023
The rising demand for the construction of pavement infrastructure creates great pressure on the production and transportation of virgin aggregates, which consumes high energy and natural resources.

A 3 Dimensional Simulation Of The Repeated Load Triaxial Test

, 2013
A typical flexible pavement structure consists of the surface, base, sub-base and subgrade soil. The loading traffic is transferred from the top layer with higher stiffness to the layer below with less stiffness. Under normal traffic loading, the behaviour of flexible pavement is very complex and can be predicted by using the repeated load triaxial ...

Estimation of Resilient Modulus for Coarse-Grained Subgrade Soils from Quick Shear Tests for Mechanistic-Empirical Pavement Designs

Designs, 2019
The resilient modulus represents the subgrade soil stiffness, and it is considered one of the key material inputs in the Mechanistic Empirical Pavement Design Guide (MEPDG).

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.
