Network Recovery Plan (road & pavement maintenance)
The Network Recovery Plan (NRP) is Barnet Coucil's £50million investment in roads and pavements between 2015 and 2020.
The investment programme covers all aspects of Barnet's highways network from road and pavements to bridges, road marking and crossings.
Network Recovery Plan aim
The aim of the NRP is to maximise the percentage of highways treated and ensure their longevity with the available funds. The maintenance programme, which is being delivered by Re on behalf of the council, saves on costly short term repairs and means roads and pavements can be used for safe, reliable travel in the long term.
How we decide which roads and pavements need work
The maintenance work within this programme is carried out to roads and pavements that have been prioritised for maintenance based on assessments. These assessments make use of information on safety defects identified by Highway Safety inspectors and customer service requests, together with condition data and information on the road use.
Roads and pavements are prioritised where the risk to users is found to be the greatest. Please be aware that the appropriate type of treatment chosen for the road is subject to the level of deterioration found in its assessment. The purpose of the Network Recovery Maintenance Plan is to best allocate the funding available to those locations requiring the works and treating them with the maintenance type most appropriate to their state.

Road works treatment types
There are a variety of treatment types that will be used to improve your roads and pavements. The below list a few of the road treatments and what they might look like.
1. Micro Asphalt
Micro asphalt is an effective and versatile sealing treatment used to prolong the life of the road by up to 10 years. It also corrects localised imperfections on the road surface and cause little disruption to residents. This treatment is used on roads that are identified as being in a mild - medium state of deterioration and does not need to be fully replaced at this stage.
This type of treatment requires laying and then rolling a thin bituminious mix onto the road surface creating a new top coat.
This treatment is used on roads that have had some deterioration of superficial damage as it seals the road from water ingress that causes cracks when it freezes. On some roads preparation works may also be required prior to laying the new material. This involves pre-patching defective areas, or removing shallow parts of the existing surface.
2. Traditional re-surfacing
This is a very effective treatment, as it provides complete renewal of the surface. This treatment is used for roads that are in a state of more severe deterioration and require a full replacement.
Resurfacing require taking off the existing surface of the road before a bitumen layer is laid, followed by a new surface. The depth of the area being treated is dependent on the condition of the road and could comprise several layers of material.
This treatment type is used where the road is found to be in too bad condition for alternative treatment types such as surface dressing and it is considered more appropriate to completely re-surface.

Pavement treatment types
Works to pavements are carried out in a variety of treatment. The treatment type and the material is chosen based on a number of local factors such as:
- Likely of cars parking or driving over the pavements
- Whether the site is within a Conservation Area
- Location of trees
- Proximity to Town Centres
Where possible, and as agreed at the Environment Committe in July 2016, the Network Recovery Plan will be using a Micro Asphalt treatment with crossovers in small block paving as the preferred treatment type.
This treatment within residential areas is more flexible to withstand vehicle run over and also the movement by tree routes. This means that it maintains a more smooth surface that is safer for residents rather than paving slabs that crack and cause trip hazards.
Conservation Areas and Town Centres
In Town centres, it is important for us to keep the paving slabs that are in keeping with the area. In conservation areas we will consult with Local ward councillors, if we feel that an alternative treatment type to the paving slabs is most beneficial, prior to any works starting.
The total spend of the Network Recovery Programme over 5 years totals £50million. The aim of the NRP is to make better use of the maintenance budget by ensuring the greatest percentage of highways is treated. By doing this work, we hope to ensure a safe and sustainable network that can be easily maintained and prolong the longevity of the roads and pavements.
In 2015/16 a total of £15 million was spent delivering the Network Recovery Programme to 13km of Carriageway and 9.6km of Footways in Barnet.
In 2016/17 we have programmed to spend a total of £10 million of the NRP budget resurfacing over 100,000m² of Carriageway and renewing 180,000m² of footways.
The improvements, when complete, will contribute to making Barnet a great place to live.
