Hi Daniel,I have been recently working on developing an unsealed road maintenance strategy for the council.The key element in prioritising and programming the unsealed road maintenance works is to know the actual condition of the road, our Asset Inspectors are continuously monitoring and measuring the roughness (International Roughness Index - IRI) and ride quality of our unsealed road network using vehicles equipped with roughness measuring devices. Eg: Roughometer developed by ARRB, RACAS etc.Further, we have classified the roads into Higher, Middle, and Lower Order Roads for the ease of prioritising based on the hierarchy and we are committing a level of service for each classification.Now with all the data from the inspections, we are fortnightly reviewing the road network to find the roads that meets the intervention level for grading based on the hierarchy (or order) to include in the program.Also, based on our available data we are projecting the average increase in IRI for different hierarchies of road, which will help us to forecast at what IRI the road will be approximately graded by the crew, if the IRI is too high we can resource it differently.We have recently adopted this methodology for the unsealed road maintenance and we have moved from a reactive to proactive maintenance methodology.This proactive maintenance methodology has ensured a better response to customers outlining when roads will be maintained as per the program and a more transparent response outlining how bad other roads are in IRI values. Also, it helps in providing a clear pathway for the depots.Please find more resources in the below link for unsealed road maintenance and material selection:https://www.arrb.com.au/bestpracticeguidesBest Wishes,Zinin Ashraf
