Abstract
Deficiency or inadequate allocation of road maintenance and development funds leads to total road network degradation. In order to ensure proper condition of road pavement with a limited budget, we need road maintenance optimisation for the entire road network. The road maintenance optimisation can be achieved using knowledge-based strategic planning systems. The collection and analysis of necessary data help design different road maintenance long-term strategies. The output results help select priorities for road maintenance and proper fund allocation. Optimal road maintenance strategy is the way to keep a fairly good road network with available funds. In addition, the road user costs can be reduced. The aim of this paper is to offer a road maintenance management system for Lithuanian conditions. The model will help evaluate the performance of the current road network and prepare a multi-year priority list for road works.

Summary
Roads make a crucial contribution to economic development and growth and bring important social benefits. Large funds are allocated to road maintenance and new road construction. Not always the allocated funds are properly distributed to where they are needed most. Road maintenance is an integral part of each road network. For the road maintenance funds to be distributed properly, knowledge-based road maintenance management is needed. Performed recurrent and periodic maintenance could drastically reduce the number of pavements strengthening works, while maintaining or even improving the existing road network condition (Burningham & Stankevich, 2005). Even better results can be obtained by performing preventive maintenance, while the road surface is still in decent condition. Preventive maintenance is performed by doing recurrent (pothole and crack repairs) and periodic (surface treatment, thin overlays) road maintenance works (Cirilovic, Mladenovic, & Queiroz, 2015). Planning can be carried out at regional road maintenance companies or even at their departments (Hafez, Ksaibati, & Atadero, 2019)
