Mechanical, durability and microstructure properties of cold asphalt emulsion mixtures with different types of filler (2016)
Journal Article

The primary aim of this study is to investigate the enhancement of Cold Asphalt Emulsion Mixtures (CAEMs) using binary and ternary blended fillers (BBF and TBF), including an in-depth assessment of the microstructure. Ordinary Portland cement (OPC),... Read More about Mechanical, durability and microstructure properties of cold asphalt emulsion mixtures with different types of filler.

Mix design considerations of foamed bitumen mixtures with reclaimed asphalt pavement material (2016)
Journal Article

In the present work, a mix design parametric study was carried out with the aim of proposing a practical and consistent mix design procedure for foamed bitumen mixtures (FBMs). The mix design parameters that were adopted in the study are mixing and c... Read More about Mix design considerations of foamed bitumen mixtures with reclaimed asphalt pavement material.

Optimizing the mix design of cold bitumen emulsion mixtures using response surface methodology (2015)
Journal Article

Cold mix asphalt (CMA) has been increasingly recognized as an important alternative worldwide. One of the common types of CMA is cold bitumen emulsion mixture (CBEM). In the present study, the optimization of CBEM has been investigated, to determine... Read More about Optimizing the mix design of cold bitumen emulsion mixtures using response surface methodology.

Effect of aggregate gradation on the stiffness of asphalt mixtures (2015)
Journal Article

Aggregate gradation plays an important role in the behaviour of asphalt mixtures. Packing of aggregate is a very important factor that will be affected by changing the aggregate gradation. Many researchers have investigated different ways of describi... Read More about Effect of aggregate gradation on the stiffness of asphalt mixtures.

The use of additives to enhance properties of pre-formed foamed concrete (2015)
Journal Article

This paper describes an experimental study of an enhancement of pre-formed foamed concrete, 1300-1900 kg/m3, by utilising two types of additives, silica fume and fly ash, to partially replace Portland cement and fine sand. It focuses on consistency,... Read More about The use of additives to enhance properties of pre-formed foamed concrete.

Improvement of the service life of sustainable self-compacting concrete SCC by integrating high dosage of cement replacement (2015)
Journal Article

Based on simple diffusion theory and a timedependent factor (?) for the chloride diffusion coefficient, chloride penetration through concrete was numerically modelled and the service life was predicted. This was done for two reference mixes (normal v... Read More about Improvement of the service life of sustainable self-compacting concrete SCC by integrating high dosage of cement replacement.

On void structure and strength of foamed concrete made without/with additives (2015)
Journal Article

A study has been undertaken to investigate the effect of different additives on the strength foamed concrete by characterising air-void size and shape parameters and identifying the influence of these parameters and changes to cement paste microstruc...

Stiffness of cold asphalt mixtures with recycled aggregates from construction and demolition waste (2015)
Journal Article

The stiffness of cold asphalt mixtures (CAM) with 100% recycled construction and demolition waste aggregates (CDWA) was studied from three different points of view: the indirect tensile stiffness modulus (ITSM), the dynamic modulus at different tempe...

Pore structure and permeation characteristics of foamed concrete (2014)
Journal Article

A study has been undertaken to investigate the pore structure characteristics, porosity and critical pore diameter of preformed foamed concrete with a density between 1300 and 1900 kg/m3, and its effect on the permeation characteristics, water absorp... Read More about Pore structure and permeation characteristics of foamed concrete.

On entrained pore size distribution of foamed concrete (2014)
Journal Article

The pore structure of foamed concrete is a significant characteristic since it affects properties such as strength and durability. To investigate these properties, the determination of total air voids content is not sufficient as the shape, size and... Read More about On entrained pore size distribution of foamed concrete.

A study into the use of crumb rubber in railway ballast (2014)
Journal Article

Ballasted track is the most common form of construction used in railway transportation due to a number of benefits in comparison with other solutions such as slab track. However, the degradation of the ballast particles and the layer settlement lead... Read More about A study into the use of crumb rubber in railway ballast.

Macro/micro-pore structure characteristics and the chloride penetration of self-compacting concrete incorporating different types of filler and mineral admixture (2014)
Journal Article

The relationship between the internal pore structure features at different scales and the local micro-characteristics of the interfacial transition zone (ITZ) to the non-steady state chloride migration coefficient (Dnssm) is investigated for one norm...

Investigating geogrid-reinforced ballast: Experimental pull-out tests and discrete element modelling (2014)
Journal Article

This paper presents an evaluation of the interlocking behaviour of geogrid-reinforced railway ballast. Experimental large box pull-out tests were conducted to examine the interaction between ballast and a biaxial geogrid. The discrete element method...
