Road Science is committed to advancing the pavements industry through innovative products and services that are developed and supported by engineering science.

As an industry, we believe there can be improvement, and through our people and processes, we are leading the charge in meeting customers’ needs. At Road Science we are providing innovative products that will help ensure better pavement outcomes now and into the future.

We are listeners

It all starts with you. Our commitment is to better understand the customer challenges, so we can continue to deliver high-performing products within increasingly limited budgets. With our end-to-end service capabilities, we can blend seamlessly into your construction journey, and have the flexibility, procedure and practices to ensure you get what you need, when you need it. We take the ‘direct route’ approach. We will never over-promise and underdeliver, and ensure our relationships are built on trust for the betterment of the industry.

We are experts

We are a passionate team of thinkers and do-ers. We constantly exceed expectations. From manufacturing and delivery of bitumen, through to laboratory services and pavement design, we have the strongest team of experts and thought leaders in the industry. Through every service we offer, we have a focus on research and development. You will feel confident that the roading solutions we are providing you – no matter how new – are always grounded in tested and proven solutions and have been designed by the best.

We find solutions

Where you see a road, we see an opportunity. We are constantly pushing the envelope to increase the quality and sustainability of our products, meaning greater cost efficiencies and longer-lasting products. With the ability to replicate real-life situations, we can predict performance and ensure it is built to last.
“By Leading transport technology, Road Science is paving the way for a stronger and more sustainable industry.” Dr Greg Arnold, NZIHT’s 2018 Conference.

Our Products

Bitumen

Road Science supplies a full range of Standard Penetration Bitumens. Common Bitumen Grades are 40/50, 60/70, 80/100, 130/150, 180/200. Our team will be able to guide and work alongside you to create or identify the right product for your need.

Bitumen emulsion

By finding a way to adjust the particle sizes of the bitumen droplets, Road Science has created an emulsion that can be sprayed at 80°C (a significant reduction from the normal operational temperature for ot or cutback bitumen of 180°C). It also cures faster, is more weather-resistant and stores for longer.
Emulsions allow the temperature of transported and sprayed bitumen to be below 100°C (typically around 80°C). This keeps everyone safe throughout every stage of handling the product.
New generation emulsions eliminate the risk of explosion as the need for adhesion and ‘cutback’ agents such as kerosene are no longer required. Roading teams are more comfortable using emulsions as they know they can return home without having to deal with fumes and kerosene clouds that hot cutback bitumen creates.
Benefit to the environment.
Every sealing season the current usage of hot cutback bitumen emits over 3.5 million litres of kerosene to atmosphere. Emulsion does not require the addition of kerosene and therefore eliminates the damage caused to both people and the environment. An independent study by CarboNZero has revealed new generation emulsions halves the CO2 emissions associated with chip sealing, this is equivalent to planting 650,000 trees.

Polymer modified bitumen

Road Science creates polymer modified bitumen products that are specially engineered for specific situations and applications. Bitumen is a material that can be modified in a number of ways. The most important thing is to keep in mind is what you are trying to achieve, we can then match the properties to your desired outcome. We have the knowledge to match specific binder modifications to your Individual surfacing issues.

“I valued the speed of the initial curing, which meant less risk of damage to the road. Lee kerosene in the mix also meant less risk of the road bleeding and black tarry stuff sticking to your tyres and going everywhere.” John Ryan, Engineer at Sigma Consultants.
