TG2 The design and use of foamed bitumen treated Containerized asphalt mixing plant is characterized by reliable function, environment friendliness and excellent performance and widely used in construction of highway, airport, dam and so on.
TG2 The design and use of foamed bitumen treated Containerized asphalt mixing plant is exclusively designed by meet the demands of overseas users.While inheriting the features of LB Series，all units can fit into 40 HQ .It can realize international standard container transportation and largely decrease transportation costs and risks, which adapts to export market.
The high level of compactness is a crucial advantage of the modular system with fixed options.Relocation of plant is made possible by the specially designed steel anchor base and hauling attachments,Meanwhile the modular structure and foundation-free fast installation are convenient for equipments transportation and removal.
In 2002, the Asphalt Academy published an Interim Technical Guideline (TG2) titled The Design and Use of Foamed bitumen Treated Materials. TG2 guideline currently includes mechanistic empirical structural design models for foamed bitumen treated materials for use in the South African Mechanistic-Empirical Design Method (SAMEDM).

When foamed bitumen was introduced to New Zealand, overseas guidelines such as the South African Asphalt Academy Interim Technical Guideline: The Design and Use of Foamed Bitumen Treated Materials TG2 (September 2002) and the Wirtgen Cold Recycling Manual (2nd Edition November 2004) formed the basis for developing best practice.

Appropriate foamed bitumen mix design method is an essential element in this technology which is increasing being used to rehabilitate Australian pavements. The Austroads Guide to Pavement Technology Part 4D Stabilised Materials provides on the selection and mix design of foamed bitumen stabilisation treatments.
successful trials using foamed bitumen stabilisation technology. 4.3 Queensland trials Main Roads has recently carried out a number of foamed bitumen stabilisation trials. 4.3.1 Gladfield Main Roads carried out its first foamed bitumen trial in Queensland on 1.6 km of the Cunningham Highway at Gladfield (21 km east of Warwick) in May 1997.
BEST PRACTICE: BITUMEN-EMULSION AND FOAMED BITUMEN MATERIALS LABORATORY PROCESSING S V KEKWICK CSIR Transportek, PO Box 395, Pretoria 0001 ABSTRACT Although accelerated laboratory curing of bitumen-emulsion and foamed bitumen treated materials is undertaken widely, there is not an accepted standard procedure.
Additionally foamed bitumen can be used to stabilize a variety of materials, including reclaimed asphalt pavement (RAP) materials. Authors attempted to optimize the design of the mineral bituminous mixtures with foamed bitumen and Portland cement (PC) in scope of the binder contents and their influence on the material properties.
One of the WMA techniques is foaming of bitumen which works on the concept of injecting cold water into the asphalt binder in order to create foam. In this study, conducted in the Rajasthan state of India, tests were conducted to adjudge the strength and moisture susceptibility of foamed bitumen-treated reclaimed asphalt pavement (RAP).

Cold recycling with foamed bitumen has become an established technology worldwide and is now increasingly moving into the focus of road authorities and construction companies for use in the rehabilitation and new construction of road pavements. Cold recycling with foamed bitumen produces flexible and highly durable base layers.

Rehabilitation using foamed bitumen has proved to be successful because of its ease and speed of construction, its compatibility with a wide range of aggregate types and its relative immunity to the effects of weather. There are now well developed procedures for the design of foamed bitumen stabilisation which should be followed.
Review of Foamed Bitumen Stabilisation Mix Design Methods Austroads 2011 1 1 INTRODUCTION 1.1 General Foamed bitumen stabilisation is a road construction technique whereby hot bitumen is used to bind the existing or imported granular material to produce a flexible pavement material for use in base
use of bitumen emulsion. Economic factors forced the designers to use foamed bitumen. Foamed bitumen has an advantage over emulsion because of the lower transport cost. In situations where contractors offered a lower price for recycling with foamed bitumen, the question was raised if the same design method can be used for foamed bitumen and emulsion.
Foamed bitumen stabilisation (FBS) involves insitu or plant mix stabilisation of pavement materials with bitumen as the primary binder. The process is used to improve the strength of granular materials while retaining a flexible pavement. The foamed bitumen content generally ranges from 3% to 4% by mass of the material being bound.

Test pits. Because of the significant financial consequences of pavement failures the minimum number of sample test pits shall be either: three test pits for treatment lengths up to 200 m, five test pits for treatment lengths between 200 and 500 m, and every 100 m for treatment lengths 500 m or greater.
