Скачать или смотреть Poor Quality Road Surface - Hale Cres, Bayview

Auckland Transport's policy is for all roads that have less than 10,000 vehicles per day (most suburban roads) to be downgraded to the cheaper chip seal surface the next time they are resealed.

On Saturday I met with Bayview resident Rudolf Arada who showed me the poor condition of Hale Crescent.
The road was resurfaced in February, downgraded from asphaltic concrete to chip seal.

Many of the stones are loose and collect at the side of the road or at the bottom of the hill. They are going up driveways and into properties, and most concerning are damaging vehicle brakes.

Chip sealed roads are known to shed stones, and Auckland Transport sweeps stones (to the side) twice after it is sealed. However the stones will continue to come loose for many months, in some cases for a year or more.

This is AT's response regarding Hale Crescent:

"It is Auckland Transport’s Policy that Chip seal surfacing must be used for resealing, except for roads which satisfy specific criteria, in which case asphaltic concrete surfacing must be used. For example asphaltic concrete surfacing must be used for resealing roads where the volume of traffic exceeds 10,000 vehicles per day, that are subject to high wear and tear (such as most cul-de-sac heads, roundabouts, sharp bends with severe flushing, stripping or skid resistance, aprons/main road intersections), in industrial/commercial areas where there is a high concentration of truck traffic, or that are subject to high usage by pedestrians, such as town centres, hospitals, shopping centres and schools.

All other road surfaces should be resealed with chip seal. In practise, this means that a low vehicle volume residential street that was previously sealed with asphaltic concrete (perhaps at the time of development) may be resealed with chip seal in accordance with the above criteria.

Once resealed, a chip surface is generally swept 3 days after and then again 2 weeks later. The sites are also monitored and extra sweeps can be programmed if required. Roads that have been chip resealed are expected to have some additional loose chip while the new surface settles and programmed sweeping will reduce the amount of the loose chip. The cooler months will also help the new surface to bed in and will result less loose chip."
