UER Foxtrot 10 End – Runway

Tender description

UER Foxtrot 10 End – Runway Resurfacing Lot 1: 4. Foxtrot Taxiway and 10-Threshold were part of the original airfield construction from 1985; 400mm PQC (pavement quality concrete) on 150mm rolled drylean concrete. In 2011, as part of Project Shackleton, it was treated with a sanded epoxide resin surface treatment (Addagrip). As with all the other areas of original concrete, these areas are suffering from ASR - Alkali–silica reaction. This is causing significant degradation, the small-scale patch repairs have been sufficient until now; however, the surface has now become a patchwork of repairs, cracks and spalling. As the number of patches and gaps between them increase the risk of a larger spall and therefore more damaging FOD; The recent Biennial Airfield Inspection report recommended that these areas are resurfaced before their condition becomes too degraded.
