Rhys O'Cain was showcasing our new Mobile Mapper at last week’s Survey and Spatial New Zealand Annual Conference. This year’s conference explored the theme of shaping tomorrow’s communities by sharing concepts, ideas and knowledge. Thank you to Global Survey https://globalsurvey.co.nz for collaborating with us and sharing a stand!
The latest Technically Speaking by Nik Vishwanath - Process Engineer in our Technical Team. Nik outlines a recent project he was involved in to eliminate Hydrogen Sulphide emissions.
Road Science is excited to announce that we can now offer high-speed surveying in motion using a Mobile Mapper. This service is now available for hire and is the only unit of its kind within New Zealand.
The Mobile Mapper, Pegasus II Ultimate (P2U), utilises point cloud and photogrammetric solutions to provide innovative ‘all you can see’ high resolution datasets, this equipment transforms the capturing and monitoring for projects and contracts.
A Mobile Mapper combines a laser scanning sensor, multiple cameras and an Inertial Measurement Unit (IMU) to deliver its survey datasets. In the P2U’s case the point cloud dataset is captured by a laser scanner collecting 1,000,000 points across 200 line scans per second to sub-millimetre accuracy. The photogrammetric survey data is stitched together from six cameras taking photos every 3m – 5m. There are two additional external cameras used for pavement analysis - crack, roughness and rut detection. Cameras can rotate 360° so they can also analyse structures.

More great work to share – this time all the way from Vanuatu.
The Road Science Laboratory business has provided IANZ accredited services for the China Civil Engineering Construction Corporation (CCECC) in Vanuatu for the Santo-Pekoa and Bauerfield Airport Runway Projects
Over the course of the project eleven staff from Road Science’s laboratory business have spent time in Vanuatu. We would like to make a special mention Frank Hu (Laboratory Section Head Auckland) who has provided leadership on this project.
Well done to everyone who has been involved in this project it shows what collaboration in action looks like.
We would like to congratulate our Technical Development Manager Darcy Rogers. Darcy has successfully completed a Master’s Degree in Science for Materials and Processing at Waikato University.
He managed to complete this Master’s while working full-time and studying part-time. Four years and two kids later he has received his degree and we are extremely proud of him!
Darcy would like to thank all his colleagues and especially his partner Charlie for all the support during this time.
Darcy’s study has already paid dividends for Road Science, with researching the feasibility of alternative pavement materials with products such Ultra Mender and the waste plastic mix (Plas Mix).
Awesome work Darcy!
Cold roads ahead! Check out Callaghan Innovation’s article on the work we have been collaborating on. Great work Nik Vishwanath from Road Science who was a part of this project.

Road Science had two presenters at the RIMs conference on Wednesday, David Alexander presented on data driven treatment selection of whether to use one or two coat seals and Simeon Hall presented about redirecting waste plastics into roading. The diversity of these presentations drives home how many different areas our innovative business is involved in – great work David and Simeon!
Today, 1:30pm at the RIMS forum Simeon Hall will be presenting – what a waste – redirecting plastic from landfill into roading, at the Rapid Downloads session.
About the presentation:
In 2017 China closed its doors to taking most plastic waste, this brought home the issue of what to do with it.
Currently there are few resources in Aotearoa New Zealand repurposing this waste into new products. Of these, they are limited to a select few types of plastics.
Local councils are under immense pressure to find a solution to their growing stockpiles of unwanted mixed plastics without having to revert to landfilling this material.
Working with councils and development partners, Road Science has developed a solution to optimise standard asphalt mixes utilising the hard
plastic waste and feeding it directly back into the local infrastructure where it came from.
Today at 10:00am David Alexander will present at the RIMS Forum - to coat or not two coat, that is the question.
About the presentation:Treatment selection can at times be quite controversial. In recent years there has been a significant rise in controversy around the use of single and two coat seals. In one camp there is a body of evidence that states that single coat seals are superior in many ways, delivering low costs and long lives. While in another camp there is a group of engineers that insist that the strength and versatility of two coat seals make them the obvious choice.
There is a middle ground that is yet to be fully explored, the area where data collected over the last 20 years, and centuries of collective knowledge and experience, work together to deliver robust and powerful decision making tools.
Through close examination of the arguments both for and against single coat and two coat seals, a door has been opened to allow for the minimisation of whole of life cost through robust and transparent treatment selection. We are designing tomorrow’s roads today; this presentation will examine if those decisions will result in the low cost of ownership for New Zealand tomorrow.
