Abstract
Blading maintenance of gravel roads is important to ensure that the functional performance of the road is optimal and that vehicle operating costs are minimized. In order to optimize the blading cycles a simple, low-cost system is required to monitor the functional performance of the road and inform the blading need. A method is described where functional performance monitoring of gravel roads can be done at a regular frequency at no additional cost to the road owner. The effect of blading maintenance decisions taken based on the use of this system on a small gravel road network is illustrated. The optimization lead to less blading requirements as only the sections where functional performance was inadequate was maintained, and in the long term the condition of the road improved through regular appropriate blading.
