La Neuve Route resurfacing works was part of the St. Aubin’s Village regeneration works. The resurfacing working area was 525m long of two-way carriageway. The primary aims of the pavement works were to replace and strengthen the pavement and improve the ride quality of the highway.
La Neuve Route is one of the main roads connecting St. Brelade with St. Helier and is therefore a relatively heavily used road throughout the day. To complete the works and maintain traffic flow, single lane closures were in operation throughout the working day, with two-way traffic signals used to manage the traffic. On narrow sections of the highway the road was closed completely with traffic diverted on agreed diversion routes as required.
The main works were to mill out 50mm thick of the existing road construction and replace it with 50mm thick 14mm Surface Course tarmac in accordance with the highways specification. Inspection covers were raised or lowered to suit the new road profile as and if required. Old inspection covers that were damaged or in a state of disrepair were identified and replaced.
Where the existing road was considered to be structurally unsound pavement strengthening was installed. This consisted of milling out 100mm deep of existing sub base and tarmac base course and laying 100mm thick of 20mm DBM binder course. Where necessary a further 150mm deep sub base was removed and 150mm thick MOT type 1 installed. Once the road was resurfaced the road markings were then painted on the road as per the drawings.
The job was programmed for 6 weeks and finished ahead of programme and within budget.
