Roundabout Resurfacing
Work Included:
Design the Traffic Management Plan for the construction phase works & gain approval from the USAF.
Close the carriageway with Traffic Management equipment and implement a site wide diversion route.
Lift the existing concrete service channel covers, across the width of the carriageway, exposing the channel and services within.
Clean out the service channel, split duct the exposed services, introduce 2no. new 100mm dia. ducts and blank off the end of the channel.
Mass fill the service channel with foam concrete, to the underside of the asphalt construction.
Break out & remove the existing speed ramps.
Cold milling plane the roundabout and approaching carriageways, at 40mm depth.
Lay regulating material, to establish level control & re-establish falls.
Machine lay 40mm thick of SMA10 surface course material, with a PSV65.
Over-band all joints.
Construct 3no. new asphalt speed humps on the roundabout approach roads.

Innovation:
A key innovation on the project was the conversion and stabilisation of the existing live service channel beneath the carriageway. Rather than undertaking a full reconstruction or disruptive utility diversion, the team developed a solution involving split-ducting existing services, introducing new duct infrastructure, and mass filling the channel with foam concrete to create a stable long-term pavement foundation.
