Development of Machine-Learning Decision-Support Tools for Pavement Asset Management
Development of Machine-Learning Decision-Support Tools for Pavement Asset Management
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…
Prolonging the Life of Road Assets Under Increasing Demand: A Framework and Tools for Informing the Development and Justification of Asset Preservation and Renewal
Prolonging the Life of Road Assets Under Increasing Demand: A Framework and Tools for Informing the Development and Justification of Asset Preservation and Renewal
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…
Strategy for an Improved Mechanistic-empirical Flexible Pavement Treatment Design
Strategy for an Improved Mechanistic-empirical Flexible Pavement Treatment Design
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.…
Options to Extend Coverage of Alcohol Interlock Programs
Options to Extend Coverage of Alcohol Interlock Programs
Despite high levels of community education and sustained enforcement, alcohol-related crashes and drink-driving offences continue to pose a threat to road safety.
Options for Rehabilitation in Interlock Programs
Options for Rehabilitation in Interlock Programs
This report examines the effectiveness of national and international programs that treat and rehabilitate drivers with alcohol dependence and the criteria used to approve the removal of interlocks.
Improved Distress Viscosity Model for Reseal Intervention
Improved Distress Viscosity Model for Reseal Intervention
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…
Development of an Aggregate Size Term for a Reseal Intervention Model
Development of an Aggregate Size Term for a Reseal Intervention Model
An existing model predicted maximum seal life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters and binder durability (resistance to hardening).…
National Guidelines for Evaluation of Alcohol Ignition Interlock Programs
National Guidelines for Evaluation of Alcohol Ignition Interlock Programs
This report considers the ideal methods for a scientifically rigorous evaluation of the possible road safety benefits of Breath Alcohol Ignition Interlock Devices. It is hoped that the core methodology suggested by this research will allow…
National Guidelines for Alcohol Ignition Interlock Programs
National Guidelines for Alcohol Ignition Interlock Programs
A number of States are considering the introduction of an alcohol ignition interlock program - entailing the fitting of a device to a vehicle to prevent an alcohol-affected driver from starting it. Within this ambit, Austroads established a team to…
