Trends in road construction costs

Future trends in road construction costs are as difficult to assess as forecasting the future prices of important components such as fuel, bitumen and crushed rock. It is evident, however, that cost increases are likely to exceed increases in the available funds for road construction, at least in the short term, with earthworks and surfacing costs in particular being affected. The higher relative rate of increase of the costs of sprayed work will require a relatively greater proportion of funds for maintenance works if the extent of resealing work is to be maintained at current levels. In this regard it should be noted that the economic benefits of prolonging pavement life by resealing, as opposed to resheeting a distressed pavement can be easily demonstrated. Increases in the cost of earthworks will require a greater justification for design standards of vertical alignment, width and batter slopes in large cuts on major rural freeways. A flexible response to changing cost structures will need to be maintained if the best use is to be made of available funds.
