1. Granular Materials for Transport Infrastructures : Mechanical performance of coarse–fine mixtures for unbound layers through DEM analysis
Abstract : Granular materials are widely used as unbound layers within the infrastructure system playing a significant role on performance and maintenance. However, fields like pavement and railway engineering still heavily rely on empirically-based models owing to the complex behaviour of these materials, which partly stems from their discrete nature.

2. DEM Modelling of Unbound Granular Materials for Transport Infrastructures : On soil fabric and rockfill embankments
Abstract : Unbound granular materials (UGM) are widely used as load-bearing layers and for embankment construction within transport infrastructures. These play a significant role on operation and maintenance of transportation systems. However, pavement and railway engineering still today rely heavily on empirical models based on macroscopic observations. READ MORE

3. Performance model for unbound grnular materials pavements
Abstract : Recently, there has been growing interest on the behaviour of unbound granular material in road base layers. Researchers have studied that the design of a new pavement and prediction of service life need proper characterization of unbound granular materials, which is one of the requirements for a new mechanistic design method in flexible pavement.

4. Characterising the Deformation Behaviour of Unbound Granular Materials in Pavement Structures
Abstract : Unbound granular materials (UGMs) used in the base and sub-base layers of flexible pavements play a significant role in the overall performance of the structure. Proper understanding and characterization of the deformation behaviour of UGMs in pavement structures are, therefore, vital for the design and maintenance of flexible pavements. READ MORE

5. Analysis of Response and Development of Permanent Deformation of Unbound Granular Materials Using a Testing Box Technique
Abstract : The main objective of this thesis is to study the response and development of permanent deformation in unbound granular materials, theoretically and experimentally. A testing box technique is used here to more closely simulate the behaviour of unbound aggregates subjected to external vertical loading. READ MORE
