Influence of waxes on adhesion properties of bituminous binders (2014)
Journal Article

The benefits at the base of WMA technologies are well established in the literature. They include the reduction in the energy consumption during the production of mixtures, the reduction in the emissions to the atmosphere in the production plant and...

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.

Accelerated swell testing of artificial sulfate bearing lime stabilised cohesive soils (2014)
Journal Article

This paper reports on the physico-chemical response of two lime stabilised sulfate bearing artificial soils subject to the European Accelerated Volumetric Swell Test (EN13286-49). At various intervals during the test, a specimen was removed and subje... Read More about Accelerated swell testing of artificial sulfate bearing lime stabilised cohesive soils.

Moisture-induced strength degradation of aggregate-asphalt mastic bonds (2014)
Journal Article

A common manifestation of moisture-induced damage in asphalt mixtures is the loss of adhesion at the aggregate–asphalt mastic interface and/or cohesion within the bulk mastic. This paper investigates the effects of moisture on the aggregate–mastic in... Read More about Moisture-induced strength degradation of aggregate-asphalt mastic bonds.

Mechanical and structural assessment of laboratory- and field-compacted asphalt mixtures (2014)
Journal Article

Compaction forms an integral part in the formation of the aggregate orientation and structure of an asphalt mixture and therefore has a profound influence on its final volumetric and mechanical performance. This article describes the influence of var... Read More about Mechanical and structural assessment of laboratory- and field-compacted asphalt mixtures.

Alternative methodologies to evaluate storage stability of rubberised bitumens (2014)
Conference Proceeding

Tyre Rubber Modified Binders (TR-MBs), produced through the McDonald wet process and used worldwide (e.g. asphalt rubber), have demonstrated various benefits to pavements and, moreover, they represent a good opportunity for recycling tyre rubber. How... Read More about Alternative methodologies to evaluate storage stability of rubberised bitumens.

Toward more realistic viscosity measurements of tyre rubber–bitumen blends (2014)
Journal Article

The measurement of rheological properties of the tyre rubber bitumen blends is often challenging due to presence of suspended tyre rubber’s crumbs. Furthermore, the phase separation during the course of measurements makes the viscosity of these non-h... Read More about Toward more realistic viscosity measurements of tyre rubber–bitumen blends.

Observation of reversible moisture damage in asphalt mixtures (2014)
Journal Article

Application of Fickian and non-Fickian diffusion models to study moisture diffusion in asphalt mastics (2014)
Journal Article

The objective of this study was to investigate certain aspects of asphalt mastic moisture diffusion characteristics in order to better understand the moisture damage phenomenon in asphalt mixtures. Moisture sorption experiments were conducted on four... Read More about Application of Fickian and non-Fickian diffusion models to study moisture diffusion in asphalt mastics.

Laboratory mix design of asphalt mixture containing reclaimed material (2014)
Journal Article

This paper presents a study on the production of asphalt test specimens in the laboratory containing reclaimed asphalt. The mixtures considered were stone mastic asphalt concrete mixtures containing up to 30% of reclaimed asphalt. Specimens were comp...

Reclaimed asphalt test specimen preparation assisted by image analysis (2014)
Journal Article

This paper presents a laboratory investigation aimed at establishing a protocol for the production of homogeneous asphalt mixtures test specimens, incorporating reclaimed asphalt by using a gyratory compactor with coring and trimming works. Stone mas... Read More about Reclaimed asphalt test specimen preparation assisted by image analysis.
