Legislative Assembly for the ACT: 2018 Week 9 Hansard (23 August) . . Page.. 3604 ..


Roads—speed limits (Question No 1598)

Ms Lawder asked the Minister for Transport and City Services, upon notice, on 3 August 2018:

Why is Mugga Lane from Long Gully Road speed limit 70kph when similar roads in NSW are 80kph or 100kph.

Ms Fitzharris: The answer to the member's question is as follows:

Mugga Lane is an arterial road carrying over 5,000 vehicles per day with a high number of heavy vehicles. As part of the review of speed limits in 2010, this section of road was assessed using the latest guides and Australian Standards. The speed limit was reduced from 80 km/h to 70 km/h, primarily due to considerations of road characteristics including crash history.

Roads—resurfacing (Question No 1599)

Ms Lawder asked the Minister for Transport and City Services, upon notice, on 3 August 2018:

(1) Why does ACT Roads use the tar and blue metal chip method of resealing roads.

(2) How long does tar and blue metal chip last.

(3) How much does it cost for tar and blue metal chip per km.

(4) What other options are there for resealing roads.

(5) Why are these options not undertaken by the Government.

(6) How much does it cost to use these other resealing options per km.

(7) How is the decision made as to which roads are chip sealed and which have other methods.

(8) Can the Minister provide a copy of the risk assessment comparing chip seal and other methods.

Ms Fitzharris: The answer to the member's question is as follows:

(1) The chip seal treatment is a preventative maintenance treatment and is applied before the road surface deteriorates to the point where damage occurs that would require costly rehabilitation treatment. Maintaining roads to be safe and useable requires the road pavement to be kept dry and for the surface to have a good skid resistance. Spray or chip sealing achieves this and is a cost effective preventative maintenance treatment. For this reason it is widely used to maintain roads in the ACT and other jurisdictions across Australia. Asphalt is mostly used to correct damage to the road
