Optimisation of pavement maintenance and renewal activities

Many professionals have some degree of unease about the method of solving the pavement maintenance and renewal planning problem and recognised this planning is a complex process. Especially, the difficulty arises when the project interaction effects are considered. This is because of the multi-directional and diversity nature of these project interactions. Generally, it is very difficult to formulate such interaction as an objective function or constrain. Before the project interaction can be properly integrated into the optimisation process, maintenance projects are usually planned without being effectively coordinated with each other. The maintenance cost is treated as a constant, as such, the opportunity of reducing the maintenance cost, practically the indirect maintenance costs, such as the user cost at the roadwork sites, are lost. An approach has been studied in this paper to introduce an alternative measure to integrate the project interaction (coordinating type) into the optimisation process. Traffic interaction and maintenance - condition interaction are considered to be in relation to the demand prediction and condition projection respectively. A pavement maintenance and renewal planning framework has been proposed. With the developed project interaction integration model, this framework supports the plans to be optimised in a state- temporal and interaction dimension.
