This report explores the use of Artificial Intelligence (AI) and Machine-Learning (ML) in pavement asset management and details a methodology for developing new use-cases. While there are some existing uses of AI and ML technology in pavement asset…

This report is the third of a series of reports for project APT6305. The first report examined the use of road-grade recycled plastics in asphalt pavements and investigated the most suitable types of recycled plastics for incorporation into asphalt.…

This report documents a project to develop a new laboratory fatigue relationship to predict the performance of foamed bitumen stabilised (FBS) materials. The project focused on extensive laboratory experiments including indirect tensile testing and…

This report provides a comprehensive overview of the initial development of various testing frameworks for the characterisation of road-grade recycled plastic, the incorporation of recycled plastics in bitumen and asphalt via various methods (wet,…

This report provides an evaluation framework, practices and supporting tools for evaluating road preservation and renewal treatment options for predominantly sprayed seal flexible pavements. It includes a compilation of case studies based on a…

This report details research undertaken to improve the mechanistic-empirical procedure for pavement rehabilitation and strengthening treatment design included in Austroads Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design.…

This report brings together five years of research into the modulus, strength fatigue characteristics of cement treated granular materials as used in road pavements. Laboratory procedures used to prepare, cure and test materials for flexural modulus,…

The laboratory characterisation of cemented materials for road pavements was completed in Austroads Project TT1359 Cost-Effective Structural Treatments for Rural Highwaysand more recently in Austroads Project TT1664 Cemented Materials…

Over the last decade a considerable amount of research effort has been focussed on the development of a repeated load triaxial (RLT) test procedure to assist practitioners in the use of natural and marginal unbound base/subbase materials in road…

An existing model predicted binder life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters, binder durability (resistance to hardening) and seal…
