Safetrack® LM Retromax ensures white lines last longer on busy Leeds Inner Relief Road.

Project Overview

The A61 Leeds Inner Ring Road is a busy thoroughfare that allows traffic to bypass the city centre. Offering a solution to the traffic congestion problem that Leeds had previously suffered from, it has been a main route since its construction in the 1970s. Thermoplastics had traditionally been used for the line markings, but they had a tendency to fade over time. Typically they would be refreshed at six-month intervals and replaced regularly – usually on a yearly basis.

Application

The refurbishment work was carried out on the A61 Leeds Inner Ring Road at the Hillage Road junction in August 2008 and during the contract, some 2,500 linear metres of 100mm lines, as well as 500 letters and 50 arrows were replaced with Safetrack® LM Retromax. A busy section of the route, the engineer wanted to avoid closing the road for the maintenance or road marking repainting a local highway engineer chose Safetrack® LM Retromax for its rapid curing properties and expected long life. Relatively new to the market, the product had proven results following two year Highways England trials on the A14 in Cambridgeshire.

The combination of Stirling Lloyd’s advanced resin technology, together with the specially selected glass beads used in the system meant that the white lines gave higher and significantly longer lasting retroreflectivity values and improved skid resistance.

Positive Results

As the Hillage Road junction is such a busy section of the A61, it was important that traffic disruption was kept to a minimum. Safe track® LM Retromax offered the client the opportunity to significantly reduce maintenance cycles, whole life costs and road closures by protecting assets for longer. Today the site clearly demonstrates the effectiveness of the product.

Importantly, seven years after the original white line installation, the results are significant. The retro reflectivity rating is still 150 MCd - 50% higher than the specification typically required after one year. This is a good indicator of the success of Stirling Lloyd’s advanced resin technology. These values are in contrast to the retro reflectivity values of the thermoplastic materials originally used on this section, which measured significantly lower and had worn away.

Jonathan Till, Highways National Sales Manager at Stirling Lloyd commented: “This project is an exceptional example and result for innovation and whole life management. The white lines are not only still present; they are also in a very good condition – bright white with a high reflectivity rating. Long term approaches to asset management are the way forward as traffic volumes increase and an unprecedented demand is put on our highways.”

Summary

The refurbishment work on the Inner Relief Road in Leeds needed to be carried out quickly, to make sure that disruption was kept to a minimum. Using Safetrack® LM meant there were fewer road works taking place and reduced congestion. The fact that the white lines are still in good condition seven years after installation is an example of efficient asset management and whole life costing.
