The condition of major roads in Canberra

There have been many cases of pavement failure in major Canberra roads over the last few years. In order to assess the scope of the problem a survey of pavement condition has been carried out on the more important roads in woden and weston creek, together with northbourne avenue and ginninderra drive. The survey revealed considerable pavement rutting and associated surface cracking in arterial and subarterial roads, particularly in the outer lanes. Of the 170 lane kilometres of arterial and subarterial roads surveyed, 30 lane kilometres, or approximately 17 per cent were assessed to require immediate strengthening. It is expected that in some cases strengthening by overlaying with 50 mm of bituminous concrete will restore the pavement shape and will be the most economical way to extend the pavement life, but in other instances complete reconstruction will be required. The cost of strengthening by reconstruction will be about four times that of an overlay. The present pavement conditions related to age indicate that design and/ or construction standards for the heavily trafficked roads are inadequate for the traffic loadings and volumes, resulting in pavements not lasting 20 years.
