Monumental report nearing completion after 23 years of research

by Australian Road Research Board on December 19, 2017

A momentous occasion in ARRB history is about to take place as the result of over 23 years of hard work by Dr Tim Martin and Mr Lith Choummanivong.

A new report on predicting the performance of Australia's arterial and sealed local roads, ‘ARR 390 Predicting the Performance of Australia's Arterial and Sealed Local Roads’, is about to be published. The report is based on the observational and experimental research data collected by ARRB between 1994 – 2017.

This research was largely funded by Austroads and the Institute of Public Works Engineering Australasia (IPWEA) as well as contributions from local government councils. The Austroads Asset Task Force (ATF) has also been involved with the work outcomes.

‘ARR 390 is about the behaviour of Australian sealed road based on Australian data, it’s not an adaptation of models based on data sourced from somewhere else. ARR 390 is relevant and appropriate for the Australian practitioner.’ Dr Martin said.

The ARR 390 document’s road deterioration and work effects models are currently being used and will continue to be used in future pavement management systems.

‘Model development is a time consuming task involving a trial and error method of problem solving. A model cannot be universal and should only be used to predict the future condition of a road section in similar traffic and climatic environments.’ said Mr Choummanivong.

ARR 390 will be referred to in the soon to be released 3rd edition of the Austroads Guide to Asset Management.

The report enables practitioners to accurately predict road behaviour over its life-cycle, as well as the best approach for maintenance and renewal.

Keep an eye out on the ARRB Latest Research page and social media to find out when this report will be released.
