Accurate and reliable data on the nature and extent of heavy vehicle use of Australia's road ... more Accurate and reliable data on the nature and extent of heavy vehicle use of Australia's road network is extremely important. One means of obtaining this data in Australia is via the use of high speed Weigh - in - Motion (WIM) technology .. Data originating from high speed WIM systems is used for infrastructure design and management, freight and trade regulation and vehicle mass limit enforcement and detection studies. This paper provides an overview of the Australian high speed WIM scene. In particular, high speed WIM system development, which has been pioneered by the Australian Road Research Board Ltd. The application of high speed WIM technology, current research in improving accuracy and experience with standardisation.

Earlier conference papers reported on the development of this program which became fully operational across Australia from mid-2008. The IAP program utilises GPS technology to remotely monitor heavy vehicles against access conditions imposed on them by Australian governments. This program is administered by Transport Certification Australia (TCA). The IAP is based on national model legislation and open, performance based specifications. The IAP program has IAP Service Providers, certified by TCA, who install type-approved telematics units and operate a certified back office service that monitors heavy vehicles and notifies jurisdictions in the event of non-compliance to defined conditions.

Earlier conference papers (2005, 2006 & 2008) reported on the development of this program which became fully operational across Australia from mid-2008. The IAP is based on national model legislation and a performance based specification. It is a voluntary program which utilises GPS technology to remotely monitor heavy vehicles against access conditions and reports any non-compliance event to the relevant Jurisdictions. In return, enrolled Transport Operators are granted access or improved access to the Australian road networks. This program is administered by Transport Certification Australia (TCA).

The evaluation was conducted by the Australian Road Research Board Limited (ARRB) during April and May 1993. The report assesses the RAMM system using the methodology adopted by ARRB for the earlier report ARR 225 - An Evaluation of Pavement Management System Packages for Local Government. It also includes questionnaire results received from surveyed users of the RAMM system. The purpose of the evaluation was to highlight the features of the RAMM system - in particular, to compare it to PMSs evaluated in ARR 225, to highlight the concerns of users and to provide advice to TNZ on possible development or improvement to the RAMM system and overall future direction.

Five broad flexible pavement types, pertinent to this research program were adopted, comprising one unbound and four differing bound flexible pavements. The paper details the results of the modelling as a function of each of the five pavement types, including independent testing and verification of the same. The analysis suggested a link between the degree of pavement ‘flexibility’ and structural capacity. Pavements with predominantly unbound materials provided a reasonable structural capacity prediction model compared to pavements with bound materials, followed by pavements with predominantly bound but stiffer materials. For all five pavement types, the structural capacity prediction model results for the full transverse profile width produced a more accurate prediction measure o...

A key input to the management of the road pavement network is its condition. Over the last 50 years, high speed, network level devices have been developed that routinely monitor pavement condition in a more objective, repeatable, reproducible and cost - effective manner. Typical of the condition parameters monitored in this fashion are roughness, rutting, macro texture and visually assessed pavement surface items via imaging systems.
Pavement structural capacity is an important condition measure of the load carrying ability of the subgrade and pavement in combination. In practice, structural capacity has been monitored at the specific project rather than network level, chiefly because of the high cost of using low speed monitoring processes. Given the cost of acquiring structural capacity data, other pavement condition parameters, readily collected at the network level using high-speed devices, are used to identify possible project level areas of investigation. The subsequent project level investigation may result in the use structural capacity testing devices.
Pavement transverse profile shape is commonly monitoring at both the project and network levels and reported as rutting. Whilst the transverse profile shape is monitored, the collected data is reduced to a level comparable to the manually collected 1.2 or 2 metre straight edge or the 3 point rut index. The author suggests that the exchange of knowledge and the possibilities available with this more sophisticated measuring process have not been fully explored. Rather, a ‘number of standards’ have been established over time and the data collection advances made, have aided in delivering these ‘standards’ in a faster, repeatable, cheaper and safer manner, but not aided in providing an improved insight to pavement behaviour and especially structural capacity.
There is a body of qualitative evidence to indicate a relationship between pavement transverse profile shape and structural capacity. The literature review undertaken suggested that pavement distress affects the shape of the transverse profile, it is also recognised that pavement distress affects structural capacity. The literature suggested that modelling the pavement transverse profile shape could provide a better insight to pavement structural capacity and overall performance, than what is currently achieved by simply reporting rutting.
