In order to complete the works, a traffic management scheme needed to be put in place which enabled two-way traffic on the northbound carriageway, thus allowing full closure of the southbound carriageway, enabling us extended daytime working for completion of the resurfacing. The Metrail scope commenced once the asphalt surface on the main carriageway had been removed down to approximately 10–20mm.
Eliminator, the GPC Advanced Technologies waterproofing system, is a rapid cure, cold liquid spray applied system, which is based on methacrylate monomers which forms a tough, flexible seamless membrane with no vulnerable joints. It’s resistant to chemical attack by oil, fuels, brine and dilute mineral acids. Where asphalt is to be laid a bond coat — also known as a tack coat — is applied as well. When it comes to the walkway, we employed Safetrack, a GCP product specifically designed to provide a durable anti-skid surface.
