Everything You Need to Know About Stimsonite Road Studs
The Stud Responsible For Creating a Brighter and Safer Journey
You can’t avoid what you can’t see. It’s a good thing that we have the data (and products) on our side.
The International Road Assessment Programme (iRAP, 2023) shows us that over 60% of road fatalities in low- and middle-income countries occur on roads that lack sufficient markings or illumination. That’s especially true in many parts of sub-Saharan Africa, where road networks struggle to keep pace with fast-growing cities.
Closer to home, the Road Traffic Management Corporation (RTMC) reported in its 2022 annual crash data that more than 35% of fatal crashes in South Africa occur at night, despite traffic volumes being significantly lower during these hours.
This highlights just how important enhanced road visibility solutions like the Stimsonite Model C80 really are. They play a crucial role in guiding drivers safely, and even more so in low-light and high-speed conditions. That’s why in today’s blog, we’re diving into everything you need to know about Stimsonite Road Studs.
What Is the Stimsonite Model C80?
The Stimsonite Model C80 is a surface-mounted prismatic road stud made for one purpose—maximum visibility. Designed using injection-moulded high-impact polymers and a specially engineered glassed face, it delivers long-lasting abrasion resistance and superior reflectivity, even under constant traffic and tough weather conditions.
This model is widely used in highways, intersections, and road construction zones, and is trusted by traffic engineers around the world for its durability and consistent performance.
Standout Features
What makes the Stimsonite Road Studs (and the Model C80 in particular) a standout product comes down to a mix of smart engineering and attention to detail. Here’s what you get with this product:
- High Reflectivity: Brightness values are up to seven times higher than ASTM standards. The Model C80 allows drivers to see more clearly well in advance.
- Cellular Lens Technology: Its unique modular lens structure allows it to maintain its visibility
even after impact damage. - Sure-Grip Bottom: A patent-pending surface design improves grip and adhesion, reducing the risk of detachment.
- Abrasion Protective Coating: Built to endure years of wear on busy roads without cracking or fading.
- Self-Cleaning Surface: This product’s materials naturally shed dirt and water, helping maintain reflectivity.
The Benefits of Using Stimsonite Road Studs
Reflective road studs aren’t just there because the rules say so; they’re proactive safety measures. Roads that use Stimsonite Model C80 see real safety improvements.
A 2021 study by the UK Department for Transport showed that reflective studs helped reduce night-time crashes by up to 70%. That’s a serious drop, all thanks to a small change that helps drivers see and react faster.
Key benefits include:
- Better Night-Time Visibility: Particularly helpful for older drivers and during heavy rain.
- Longer Product Life: Fewer replacements = cost savings + fewer road closures.
- Weather Resistance: Built for SA’s extreme sun, rain, and dust.
- Improved Traffic Flow: Helps keep lanes clearly marked, reducing confusion and hesitation.
Colour Options & Configurations
Each Stimsonite Road Stud colour configuration serves a unique purpose in traffic management:
- White/White – Indicates lane lines or the centre of the road.
- White/Red – Often used at the left-hand shoulder.
- Red/Red – No entry or wrong-way indicators.
- Yellow/Red – For caution zones or medians.
All of these configurations are bi-directional, meaning they reflect light from both directions, increasing visibility from either lane.
Technical Performance vs Standards
Want to know what makes the Model C80 such a standout? Let’s see how it measures up against the ASTM D-4280 standard—it doesn’t just meet the mark, it blows right past it.
| Property | ASTM Minimum | Stimsonite C80 |
| White Reflectivity | 279 mcd/lux | 2,026 mcd/lux |
| Yellow Reflectivity | 167 mcd/lux | 1,552 mcd/lux |
| Red Reflectivity | 70 mcd/lux | 494 mcd/lux |
| Compressive Strength | 6,000 kg | 41,580 kg |
| Dart Drop/Lens Impact | Pass | Pass |
| Abrasion Resistance | Pass | Pass |
It’s clear. The Stimsonite Model C80 don’t just meet global standards for reflectivity, durability, and strength. They just raise the bar.
Installation Made Simple
Proper installation ensures that the performance of your road studs matches the quality they were built, and with this product, it’s even easier than you think.
Here’s how to install the C80 model:
- Clean the surface of all dust, sand, oil, and loose debris.
- Apply Our Epoxy Adhesive to the bottom of the stud.
- Press the stud firmly into place and allow time to set before exposing to traffic.
This simple installation goes a long way. It creates a bond tough enough to handle even the heaviest traffic, from freight trucks to full buses.
