RESULT AND APPLICATIONS OF DETERIORATION MODEL IN ROAD ASSET MANAGEMENT (Paper 857)

In order to properly manage the increasing quality road asset on account of huge investments on rehabilitation, upgrading, widening and new construction of roads and highways in the last decade, a road deterioration model was established during the study in Ethiopia as per the actual maintenance requirement on the principles of life cycle cost analysis, based on traffic loading, road geometry, pavement type and condition, terrain, and climate for different road types and thus, ensuring adequate road maintenance strategies and standards, i.e. timely and proper maintenance interventions to an acceptable level of service in view of ensuring uninterrupted, sustainable, efficient, effective and safe road transport system in the country.
Accordingly, this paper highlights the result and applications of deterioration model in road asset management to preserve the national assets as well as bringing down the overall transport system cost in the country.
There are various applications of the road deterioration model, which can, inter alia, be applied to determine and rationalize a number of road user charges, such as, estimation of the overloading fines/fees on account of damages caused by the overloaded vehicles in the country, and determining the rational road user charges, to cover the extent of road deterioration, e.g. Mass Distance Charges (MDCs) to be adopted for the paved road network in various developing and developed countries.
