Design of pavements containing foamed bitumen recycled layers
2009Cold 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, 2010As 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 ...

Performance of foamed bitumen-stabilised mixtures
Proceedings of the Institution of Civil Engineers - Transport, 2007Mixtures 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, 2001A 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.

New Zealand Experience with Foam Bitumen Stabilization
Transportation Research Record: Journal of the Transportation Research Board, 2004Foamed 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.

Laboratory Mix Design Procedure for Foamed Bitumen Mixtures
Transportation Research Record: Journal of the Transportation Research Board, 2014The primary objective of this study was to propose a practical and consistent mix design procedure for foamed bitumen mixture (FBM). The main focus of the proposed methodology was the use of the gyratory compaction method. The study maximized the mix design parameters, such as mixing water content (MWC) and compaction effort.

Study of aggregate gradations in foamed bitumen mixes
Road Materials and Pavement Design, 2012This 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.
