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.

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.

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 ...

Immobilization of slag material by foam bitumen

1994
With the foam bitumen technique it is possible to coat cold and wet granular materials with bitumen. It is not necessary to heat or dry the materials. With this cold stabilisation procedure a bituminous bound foundation layer can be achieved with the characteristics of a bituminous concrete asphalt layer.

Development of Bitumen Selection Criteria for Cold Recycled Bituminous Mixes with Foamed Bitumen

Transportation Research Record: Journal of the Transportation Research Board
The objective of the present study was to develop bitumen selection criteria for cold recycled bituminous mixes (CRBMs) with foamed bitumen. The criteria were developed by investigating the influence of various factors, such as physical properties of bitumen (specifically viscosity), foam characteristics, and their interaction effect on ...

New Zealand Experience with Foam Bitumen Stabilization

Transportation Research Record: Journal of the Transportation Research Board, 2004
Foamed bitumen stabilization is burgeoning steadfastly and internationally. Although it involves higher initial material costs than cement or lime stabilization, it offers the advantages of being free from transverse shrinkage cracking and of being a fast technique that minimizes traffic delays.
