Safetrack® LM Retromax provides long term solution on major roundabout.

Project overview

Parkhouse Roundabout is a major roundabout located in Carlisle, Cumbria. The roundabout was opened in 2012, boasting over 250 road numerals and arrows guiding approximately 10,500 motorists to their destination each day.

However, the markings on the road were wearing quickly and within just three years they were in need of refreshment for a second time. This was not only creating unnecessary traffic disruption, but also raising concerns for driver safety, as a result Stirling Lloyd’s Safetrack® LM Retromax was chosen to provide a longer term solution.

Product Selection

With the roundabouts numerals and arrows needing to be refreshed every 12-18 months the client, Connect Roads, wanted a solution which would see a significant increase in the service life of the road markings, saving time and disruption as well as minimising maintenance costs.

Convinced of the benefits on offer, Connect Roads specified the use of Stirling Lloyd’s Safetrack® LM Retromax system to overcome the previous issues with line wearing. Exceptionally hard wearing, Safetrack® LM Retromax is an advanced marking system based on Stirling Lloyd’s proprietary Esselac® resin technology and is proven to last typically five times longer than thermoplastic or spray paint markings.

Safetrack® LM Retromax is a fast curing, cold applied, temperature tolerant system which can be applied all year round, enabling works to be carried out at the optimum time of year while keeping road disruption to a minimum.

Not only does the Safetrack® LM Retromax system improve the cost-effectiveness of road markings, but it also improves driver safety by incorporating reflective glass beads for added retro-reflectivity.


With the roundabouts 250 markings to complete, the project involved the application of approximately 1000 linear metres of Safetrack® LM Retromax.

The systems ease and speed of application enabled the installer, Gordon Graham Roadmarkings Ltd., to complete the works in just one day and the fast curing nature of Safetrack® LM Retromax, with the system fully curing within the hour and being able to accept traffic at this point meant the Parkhouse Roundabout could be quickly returned to full service, minimising disruption on this busy route.


The application of Stirling Lloyd’s Safetrack® LM Retromax means that now the markings on Parkhouse Roundabout will need to be refurbished or replaced every 7 – 8 years rather than the only 12 – 18 months previously experienced, significantly reducing future disruption on this major route and reducing the safety hazards for motorists using the roundabout.

In addition the use of the Safetrack® LM Retromax system will provide an estimated saving of £80,000 in roadmarking costs on the roundabout throughout the period of the PFI – and this is without even taking into account the associated traffic management costs and the wider economic costs to the local community of avoidable maintenance work.


Stirling Lloyds Safetrack® LM Retromax system replaced previously rapidly wearing out road markings, providing a durable, long lasting solution which will require minimal maintenance. Its use will mean the projects aim of reducing health and safety risks to motorists and minimise disruption by significantly diminishing the need for regular upkeep of the road markings will be met. Applied in September 2015, the markings still look as good as new.
