“…RONET sets the optimum standard of road maintenance for each road or homogenous group of road sections and determines the funding level characterised by difference between current and required maintenance costs (Mladenovic et al, 2011). Due to its simplicity and low operating costs (based on requirements for financial and constant data updates), RONET could be useful not only for nation size network but also for small district-based road agencies (Hafez et al, 2019).…”

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.

“…The periodic intervention typically includes major rehabilitation actions such as plain overlay, cold milling and overlay, and reconstruction, which are capable of restoring the pavement structural integrity. Because huge nancial resources are required to maintain and restore the pavement network, a mathematical tool called pavement management system (PMS) has emerged to assist decision-makers in obtaining the optimal maintenance and rehabilitation (M&R) plan that can maximize pavement condition subject to budget limitations [4][5][6][7][8][9].…”

“…The (M2) model is much more practical than the (M1) model as it limits the maintenance improvement to only one-state upgrade regardless of the number of transitions deployed. However, the (M2) model creates "trapping" states, those states associated with zero maintenance variable rates, namely states (3,5,7,9). This means pavements accumulating in these states over time as a result of deterioration have no chance for upgrade unless other M&R actions are considered.…”

“…and 8 has resulted in substantial increase in the annual PCI value during the rst two M&R cycles, then maintained somewhat steady PCI values for the remaining M&R cycles.Table4provides the annual restored state probabilities, SM i (k), for sample Plan 1 considering the (M2) model with project-level approach. It can be seen that states(3,5,7,9) have become like "trapping" states with only major rehabilitation work can help reduce the pavement accumulations in these states as outlined in the methodology section. Also, the states (2, 4, 6, 8, 10) associated with the ve relevant (M i,i−1 ) variables have been assigned zero state probability values.…”

this paper proposes three different models for investigating the long-term performance of routine maintenance works using the discrete-time Markov model. The three models are called (M1, M2 & M3) models representing specific forms of the transition probability matrix. The (M1) model only incorporates the routine maintenance variables (Mi,i−1) under the assumption of only one-state upgrade. The (M2 & M3) models incorporate both routine maintenance variables (Mi,i−1), and major rehabilitation variables (Qi,1) under the assumption of upgrade to condition state (1). Two different modelling methods are proposed for pavement long-term performance investigation in the presence of maintenance and rehabilitation (M&R) variables. The first one is the project-level approach as applied to small pavement networks which assumes that all M&R works can be performed in a short-time period. The second one is the network-level approach which requires the M&R works to be spanned over the entire year as applied to large pavement networks. A model cost-effectiveness index is proposed to evaluate the long-term performance of potential M&R schedules under unconstrained annual budget, while M&R variable cost-effectiveness indices are proposed as useful parameters for yielding optimal M&R schedules under constrained annual budget. The sample results indicated the unrealistic performance of the (M1) model, and the usefulness of the (M2 & M3) models in yielding reliable long-term M&R schedules. The unconstrained approach indicated the optimal M&R schedule is the one associated with highest M&R variable values, and the constrained approach revealed that the optimal solutions are dominated by M&R variables with lowest cost-effectiveness indices.
