Permanent Cold-Applied Ironwork Reinstatement on Chiswick Roundabout (July 2023) November 2024 Inspection
Case Study
The Challenge
This high traffic ironwork reinstatement presented a challenge: finding a solution capable of withstanding immense daily traffic without frequent repairs.
Traffic data highlights this demand:

Completely Cold Applied System Used
Magma PermaFyx L273 | Permanent Asphalt Repair Kit
PermaFyx L273 is a permanent asphalt repair product based on high-performance cold applied MMA (Methyl Methacrylate) resin which will outlast the surrounding substrate.
This is the perfect solution for small defect repairs such as potholes and ironwork surrounds, where itโs not practical to call out a hot box, but a permanent repair is required.
PermaFyx L273 provides a professional finish replicating a hot-lay asphalt, blending into the surrounding surface and meets all requirements for use on highways.
