Sealing Porirua's roads

Porirua roadsealing programme

Porirua City Council maintains around 251km of roading network through an annual resurfacing programme and on-going maintenance.

We completed our planned summer chipsealing programme during February and March 2020 (see table below).

 Chip seal is used in most instances, as per Council policy, to improve the life and value for money of our roads.  

Our asphalting resurfacing programme was carried out in August 2019. This programme targets areas of high-stress such as cul-de-sac turning circles and busy intersections.

**Note: Residents are given five days notice of planned works (which can be weather affected) and roads are swept 48 hours and then 7 days after being chipsealed to allow time for the chips to bed in.  Please treat the roads with care during this time.

Our roadsealing programme

Porirua’s annual resealing programme looks to optimise the life of the city’s roading network through cost effective, value for money, maintenance.

The programme is an integral part of the city’s asset management strategy. It is developed from the city’s 30-year forward works programme, which is prioritised through an annual condition rating of the entire network; looking at its age, defects, maintenance costs and future maintenance risks.

Chip seal vs Asphalt

Chip seal is considered the best option in most reseal situations in terms of efficiency and function and it is the preferred option in most developed countries.

Asphalt surfacing is preferred in high-stress areas such as sharp turns, busy intersections and steep grades.

It is important to note that asphalt surfacing is six times more expensive than chip seal but does not give six times the life. It is also more expensive to maintain.

Chip seal consists of a membrane layer of bituminous material followed by stone chip. There are numerous types of chip seal and individual designs to determine the right one to use are done for every road section.  The design takes into consideration the current roughness of surface, the volume of average annual daily traffic and likely stress to ensure the final chip seal design used delivers sufficient waterproofing and skid resistance.
