(4) The expected average time before a road would need to be resurfaced again is 20 years for territorial roads and 25 years for municipal roads, however the actual age varies significantly with different treatments and the different in-service conditions like traffic volumes, type of traffic, construction history, damage to the surface etc.
(5) (a) Roads ACT is a member of the national organisation of state road authorities (Austroads) and the Australian Road Research Board (ARRB) and uses the results of their research and modelling and inter-jurisdictional fora to keep abreast of alternative materials becoming available.
(b) The following table shows the approximate extra cost for using various more expensive materials in road maintenance resurfacing.

(c) In financial terms, savings would not be realised by using more expensive materials in road resurfacing that would increase the number of years before a road would need to be resurfaced. For example, a road that is resurfaced by resealing typically needs to be resurfaced every 15 years. A road resurfaced using asphalt typically needs to be resealed every 18-20 years. The high capital cost of using asphalt does not justify the 3-5 years savings on frequency of resurfacing in financial terms.

(2) Which stakeholder groups were consulted as part of the community consultation program.
(3) Which Tuggeranong suburbs were included as part of the letterbox-drop in relation to this consultation program.
