With up to 21,000 vehicle or cycle journeys along the route, between 7am and 7pm, on a typical day, the project was required due to deterioration of the road, over a number of years.

The scheme, which ran for nine consecutive shifts, involved the team planing the existing carriageway to a depth of 90mm, and then installing geotextile - apolymer coated glass-fibre grid for asphalt reinforcement, which is used to prevent reflective cracking and to extend the life of new bituminous layers. Binder and surface course were then laid to form the new carriageway. During each phase, ironworks were adjusted and replaced, where necessary. Warm mix asphalt was used throughout, which is now a standard practice in Camden.

The project was split into multiple phases to enable vehicular traffic to continue moving, as much as possible, reducing disruption for thousands of users. Seven of the phases were carried out under lane closures and local diversions, with only two phases requiring full closures. Road traffic control was provided by VolkerHighways’ in-house traffic management division - specialists in providing traffic management solutions across a range of road networks.

Jak Edwards, contracts manager for VolkerHighways, said: “This was a monumental task due to the sensitive location, which is used by thousands of roads users every day. This is a great example of what can be accomplished when the specialist departments within VolkerHighways work closely together.”
