Improved efficiency – Using purpose built specialist plant and specialist equipment to get the job done effectively and quickly
Cash savings – Reducing pavement design thickness, lowering carbon footprints
Delayed interventions – Using patented technology to produce a robust and long lasting result
Cash savings – Reducing the need for reactive maintenance and further closure of the runway
Improved efficiency – A runway that could handle the elements and keep people connected
Cash savings – Ensuring the right people and tools for the right job
The most vital part of any airport is the runway. So when the RAF Northolt runway started showing signs of reflective cracking, Asphalt Reinforcement Services knew what was needed. They were looking for the best solution for strengthening the airfield surfacing and slowing the reflective cracking process, while staying within budget.
Colas, the surfacing contractor, chose to use a specialist team here at Asphalt Reinforcement Services to install GlasGrid®. The main works involved installing GlasGrid® CompoGrid CG100 to a milled concrete surface, using 200 pen straight run bitumen at 1.1l/m² with purpose built applicators It was then overlaid with binder and a surface course. GlasGrid® geogrid CG100 was also used on top of a regulating layer to prevent reflective cracking and to help prolong the life of the runway.
Finish / Destination
Getting the job done properly meant using a purpose built specialist plant and specialist equipment. This allowed teams to be able to install GlasGrid® easily and quickly, reducing disruption on site and ensuring products were installed to a high standard without compromising safety.
GlasGrid® CompoGrid CG100
GlasGrid® is an exceptionally strong reinforcement grid structure that is able to control crack growth and increase load bearing capability. It can extend pavement life up to a factor of 5. Because it permits thinner pavement design whilst reducing the carbon footprint, cost is kept to a minimum. GlasGrid® CompoGrid CG100 is ideal for use when cracking occurs over the whole surface or where reinforcement is needed right across the whole width.
