Rheological Investigations on Foamed Bitumen

Airfield and Highway Pavement 2013, 2013
The increased workability of the mixture of foamed bitumen with aggregate particles is largely influenced by the rheological properties of the foamed binder during mixing and subsequent compaction. Since foamed bitumen is a twoconstituent system of air bubbles entrapped in the binder, a complex behavior is expected as the temperature reduces during ...

Characterization of foamed-bitumen stabilisation

International Journal of Pavement Engineering, 2007
Since 1997 Main Roads has been developing the foamed-bitumen stabilisation technique to provide a more flexible and fatigue resistant stabilisation treatment suitable for Queensland conditions. Several projects have been completed using this technique. Supplementary specifications have been also developed based on the experience to date.

Decay properties of the foamed bitumens

Construction and Building Materials, 2006
Abstract This paper presents study on decay properties of two foamed bitumens. Foaming tests under various conditions were carried out to investigate decay properties of two types of bitumen: Penetration-grade 60 (PG 60) and Penetration-grade 100 (PG 100). Decay data were recorded and analyzed.

Performance of foamed bitumen-stabilised mixtures

Proceedings of the Institution of Civil Engineers - Transport, 2007
Mixtures stabilised with foamed bitumen are commonly made with recycled aggregate, typically reclaimed asphalt planings. These mixtures are influenced by many factors, which require full consideration during the production and construction stages. Untreated recycled material is often unsatisfactory owing to the particle size distribution and high ...

Some Characteristics of Foamed Bitumen Mixes

Transportation Research Record: Journal of the Transportation Research Board, 2001
A study was conducted at the School of Engineering of Griffith University on characterization of a range of foamed bitumen stabilized mixes in the laboratory. Marshall and servo-controlled gyratory compactors were used in specimen preparation. A closed-loop, servo-controlled dynamic loading system was utilized to determine the resilient modulus. It was

Design of pavements containing foamed bitumen recycled layers

2009
Cold in place recycling of asphalt pavements with foamed bitumen is a technique traditionally used for base course or subbase construction on low or medium volume roads, but in some recent publications it has been used on heavy trafficked roads to build base courses upon which the bynder course is laid directly.

Bitumen Chemical Foaming for Asphalt Paving Applications

Industrial & Engineering Chemistry Research, 2010
As an alternative to traditional hot-mix asphalt paving, bitumen foaming technologies have been extensively used in road recycling over the last decades. However, much more work on the use of foam-enhancing chemical agents is needed. This research deals with the influence that temperature and processing protocol exert on the bitumen foaming process ...

Study of aggregate gradations in foamed bitumen mixes

Road Materials and Pavement Design, 2012
This paper investigated the influences of aggregate gradation on the mix design and mechanical properties of foamed bitumen mix (FBM). Various gradations with different compositions of the fine aggregate fraction (FAF) and coarse aggregate fraction (CAF) were designed and quantified as gradation shaper factors for the different fractions.
