Moisture testing for roads
Greg Arnold, Road Science

High moisture within the pavement accelerates pavement deterioration, and ensuring the water is kept out of these pavement layers will increase life and save in maintenance costs. A high-speed moisture survey technique used overseas, which utilises ground penetrating radar combined with video and laser LIDAR was used on a range of roads in the lower North Island. A unique Moisture Damage Index was developed for use in New Zealand to enable the identification of high moisture levels at three different depths (top; middle; bottom) in 2m increments along the road using results from the ground and air coupled radar. The results and benefits of these trials will be reported to the group with feedback requested on potential benefits uses and needs for this technology in New Zealand.

Greg Arnold is a member of the technical team with Road Science. He graduated with a Doctor of Civil of Engineering at the University of Nottingham in 2004. His thesis topic investigated the rutting behaviour of granular materials. Prior to joining Road Science, Greg worked for NZTA as their Engineering Policy Manager and was the director of Pavespec Ltd undertaking pavement research and Repeated Load Triaxial testing.

Multi-Speed deflectometer – an innovative tool for local authority network asset management
Gina Schmitz, GeoSolve

The Multi-Speed Deflectometer (MSD) is a new, innovative technique for determining pavement structural capacity and remaining life at normal traffic speeds. It combines the efficiency and continuity in relation to testing speed and test spacing of the Traffic Speed Deflectometer (TSD) with the compactness of the Falling Weight Deflectometer (FWD). Like the TSD, the MSD is a network screening device, which captures images and collects data from multiple sensors, averaging them to 10m or 20m intervals, enabling a near-continuous profile of pavement structural life. It is not intended for use on highways with high structural capacity (i.e. high volume roads) because these require the greater resolution obtained from TSD testing. However, the MSD is ideal for most low volume roads and is therefore particularly useful for New Zealand local authorities requiring effective asset management as it combines manoeuvrability, reliability and availability with collection of pavement structural data at minimal cost.
The testing vehicle can be readily equipped with sensors on each side, collecting structural data from both wheel paths of low volume roads. Additional sensors can be added for simultaneous high speed surface condition data (rutting, roughness, cracking, macrotexture and skid resistance). Where roads are found to have more than 25 years life, no further investigations are warranted. Where roads are found to have minimal life from the preliminary screening with MSD, more costly testing and analysis (e.g. deflection testing) need only be applied to those sections of each road which are identified as critical. The outcomes are Forward Work Programmes using mechanistic methods for informed asset management without the inconvenience of traffic control and substantial cost savings for local authorities.

Gina is part of GeoSolve’s Pavement Analytics Group and is involved in deflection data analysis (TSD and FWD), pavement design, research and development. She is a regular contributor to the latest developments in pavement structural evaluation ( Recent focus has been on the Regional Precedent Performance Project, establishing and verifying “regional” pavement structural design criteria for roading networks in individual provinces in New Zealand. The emphasis of this study is to facilitate implementation of mechanistic procedures encompassing all distress modes, to provide more reliable prediction of pavement life and more efficient rehabilitation design for both unbound granular and stabilised pavements. This research was originally based on FWD data and is now being applied to TSD data as well.

A regional data collection strategy for Waikato Councils
Joanna Towler, RATA – Waikato Road Asset Technical Accord

In 2014 the Waikato Mayoral Forum resolved to establish a Waikato Centre of Excellence (to be known as the Road Asset Technical Accord – RATA) in road asset management to deliver more advanced asset management than could be achieved independently, thus assisting better council decision making and reducing whole of life costs for roading assets. In 2015 it was agreed that RATA should be a permanent business unit.
The consistent collection of minimum road asset management inventory and condition data has been in place since 2015 for the 9 RATA Councils. Much has been achieved in establishing a consistent asset management process and philosophy across the nine councils.
RATA Councils have indicated their willingness to move to a more comprehensive data collection strategy to enhance asset management practices and investment decision making.
RATA has developed a Regional Data Collection Strategy for the 9 RATA councils, and prepared a business case supporting the anticipated future higher level of funding requests to the NZ Transport Agency under Work category 151: Network and asset management.
This paper outlines the journey RATA has taken, to the current point, and the development and benefits of the Waikato Regional Data Collection Strategy.

Joanna has had 22 years experience in the roading industry in New Zealand and Fiji. She had 15 years at the NZ Transport Agency where she was responsible for New Zealand’s technical specifications for road surfacings and delineation. Joanna spent 18 months working in Fiji for MWH consultants as a senior road design engineer before returning to New Zealand in late 2016. During 2017 Joanna worked for the Waikato Road Asset Technical Accord (RATA) providing expert roading asset management advice and support to nine Waikato Councils. Joanna has recently left RATA and taken up a new role as Roading Manager at Otorohanga District Council, where she continues to broaden her roading asset management and engineering skills.

New technologies and approaches to deterioration modelling in the operational context
Fritz Jooste, Lonrix

This presentation discusses new technologies that can lead to improved deterioration models. This presentation focusses specifically on short to medium term deterioration modelling in an operational (as opposed to strategic) context, and explains the different needs and focuses of these two modelling scenarios. The need for operational models has become more crucial to meet the needs of asset engineers involved in Network Outcomes Contracts (NOCs) in New Zealand. The implementation of new modelling approaches and technologies such as machine learning and “big data” concepts are discussed and illustrated. The presentation also discusses the impact of data variation on model accuracy and presents alternatives to the use of single number statistics to represent modelling segments (e.g. using an average or percentile value to represent rut depth on a segment). The possibility of developing models which seamlessly take into account available data to determine most likely short term increments in performance parameters such as rutting or roughness is discussed. The use of machine learning to determine erroneous trends and remove them from the model using data mining and pattern identification techniques is also discussed. The presentation concludes with specific suggestions for how emerging technologies can be used in deterioration models in New Zealand.

Fritz Jooste has been working in the field of pavement design and asset management for more than 25 years. He earned his PhD from Texas A&M University in 1997 and since then has been involved in primarily in research and development of systems related to pavement design and asset management.  Fritz is a founder and director of Lonrix Ltd.

Predicting the wall of wood
Hamish Featonby, Downer NZ

Many rural Councils across New Zealand are struggling to manage the impact of forestry on their road networks. This is expected to get worse over the next decade, as the dreaded ‘wall of wood’ becomes a reality. Whanganui District Council, through the Whanganui Alliance, have focused on improving their understanding of the impact it will have on their service delivery. The increased confidence in demand management, by understanding the impact of changing traffic volumes over time, has allowed decision makers to strategically focus investment in maintenance, renewal and improvement – increasing value for money.
As part of development of the 2018-21 Activity Management Plan, Whanganui incorporated the predicted change in traffic volumes within their pavement deterioration model. This has provided long term level of service and cost of service indications, enabling the confirmation of funding levels required to deliver appropriate customer levels of service, which takes into account the impact of forestry harvesting activities – something not widely done in New Zealand.
The presentation will discuss how by using a methodical approach we were able to map the expected forestry harvesting, predict the changing traffic loading, then use dTIMS to determine the expected impact on a year to year basis. This indicated how the demand changes on the network would impact condition over time, then use the information to proactively focus renewals investment to minimise the logging effects. It will also highlight how dTIMS was utilised with support tools such as MS Excel, QGIS and Google Earth to quantify and visualise the changes over time.

Hamish is the Asset Engineer for the Tararua Alliance and is a contributor to many national Downer Asset Management projects including being part of the Downer dTIMS team, for both NOC and Local Authority Contracts. He has been with Downer for almost 10 years including time in both contract management and asset management roles.

Can you see the cracks – HSD cracking collection
Scott Verevis

For some time now, Whangarei District Council (WDC) haven been involved in automated data capture for local roads.  Capturing High Speed Data (HSD) to State Highway standards since 2009.  This presentation will explore what WDC and now their partners, have been up to in the space of the HSD collection, specifically HSD automated Cracking Data collection for sealed roads since 2013.  The presentation will look at:

– How WDC kicked the process off, what drove us to go there? Considering the system by age standards was in its infancy in New Zealand
– What we found in the process? Exposing some of the cracks on the way and realising some benefits
– How are we using the data today, what has been the impact?
– What are the next steps, exploring the eternal questions; Are we there yet? And where is there?
This presentation will look at the process the inputs and outputs but will not deive into the real boring techo stuff.  We will also discuss how two neighboring councils, relatively poor and small were keen to get involved and what this meant to the process, cost savings, efficiencies and the opportunities this presented.  The presentation will provide the audience with a broad understanding of the HSD Cracking collection in an applied environment.
– Whangarei District Council roading manager for putting faith in where we were heading
– Kaipara District Council roading manager understanding that where WDC were heading was a no brainer even for small council such as theirs
– Far North District Council for challenging what we were up to
– Data Collection Limited (DCL) for supporting us in this process and being very flexible, knowledgeable and honest
