Australian and International Bituminous Binder Specifications
This literature review covers the development of bitumen specifications and test procedures from Australia, USA, Europe and South Africa. In order to have a better understanding of the imported bitumens into Australia, this report discusses the…
Development and Application of a Horizontal Stress Transducer
This report describes a measurement technology with the capacity to provide estimates of the vehicle-pavement interaction through measurements of the horizontal stresses resulting from vehicle movements. A summary of overseas technology leading to…
Development of Laboratory Measures to Assess Surfacings used in High Stress Applications
This report describes the development of a laboratory test used to assess surfacing response to horizontal stresses and contributes a stronger performance focus for the specification of materials used in bituminous surfacings used in these…
Management of an Asphalt Road Trial
The establishment of an asphalt field trial requires considerable planning and usually involves significant resources. The selection of a trial site can significantly affect the likelihood of a clear outcome. The information provided will assist in…
Review of Foamed Bitumen Sealing in Australia
In 1993, Austroads performed an extensive trial of foamed bitumen sprayed sealing in Australia, as a part of environmental and energy effective sealing technology development program. The trials were conducted in various states and reported to be…
The Results of Testing Overseas Bitumen
Overseas bitumens are now being imported into Australia and the properties of possible future imports were evaluated. Overseas bitumens from various sources were obtained and subjected to a range of chemical and physical tests. These included…
Bitumen Emulsions
This report reviewed overseas and Australian experience in using bitumen emulsions. Increasing economic and environmental pressures have induced an increase in demand for the use of bitumen emulsions overseas. However, emulsion sprayed seals are…
Seal Distress Mechanisms: An Initial Study into Flushing
A review of bleeding or flushed seals was undertaken to determine what physical changes had taken place within the seal that had resulted in the binder lying at or close to the surface. The evaluation process used a visual appraisal and a digital…
Technical Basis of the Austroads Design Procedures for Flexible Overlays on Flexible Pavements
This publication describes the development of the flexible overlay design procedures included in the Austroads Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design. The origins of two procedures are detailed: a design chart…
Construction Report for Cemented Test Pavements: Influence of Vertical Loading on the Performance of Unbound and Cemented Materials
This report details the construction of two test pavements which were used for an assessment of fatigue performance of cemented materials under full scale, rolling wheel, accelerated pavement testing (APT). The test pavement consisted of a sand…
