Covering a total length of 4km, the improvement works drew on a wide range of skills from across the business, including planing, surfacing, traffic management and road marking as well as kerbing, drainage repairs and the installation of road signs. The team completed a two-phase package of works which saw them remove the asphalt along the east ramp and inbound carriageway leading into the central terminal area of the airport before laying a new high-quality mix.
The team successfully maintained a challenging schedule to ensure that the airport remained fully operational and with minimal disruption to customers. Work on the project was limited to a short window from 10pm until 4am, with no flexibility for any element of the project to overrun.
In line with its focus on self-delivery, FM Conway supplied materials for the project from its Heathrow asphalt plant. This included FM Conway’s high-performance Surephalt HD PMB range in the base, binder and surface course layers. Where a deeper pavement was required, the team used an EME2 15/25 pen material to give stiffness and durability to a failing substrate on the tunnel approach road.
