An Approach to the Methodology and Technology Used to Develop a Maintenance Management Framework for Pavements in the Spanish State Road Network

Within the competence of the General Administration of the Spanish State, road pavement maintenance policies follow different management types. On the one hand, 43% of the road network (30,502.12 km of carriageway) uses a "direct" management model, which means that the Public Administration carries out all necessary actions in order to assess the condition of road assets and to determine the works required for their proper maintenance. On the other hand, there is the “Plan for the Upgrading of First-Generation Roads”, whereby the Government outsources the maintenance of road assets to private companies by means of a shadow toll system. Finally, the toll road model implies that the Public Administration delegates most management tasks to a concessionary company. This paper describes and analyzes the different methodologies and technology used in the first two models. Additionally, it includes remarks on the importance of the technological framework to foster convergence between public and private management domains. To this purpose, as a practical example of this confluence, among all web-based tools included in the platform, this paper portrays the one used to generate and update the pavement data inventory. This tool has been chosen because road pavements are a publicly-owned asset whose knowledge is essential for the development of future maintenance policies. All around the world, one of the key objectives of the authorities responsible for the management of infrastructures is to ensure that proper maintenance is accomplished, in accordance with the appropriate quality levels. In Spain, within the competence of the General Administration of the State, the legal framework of pavement maintenance policies is a set of regulations and guidelines drafted by the Directorate-General of Roads, which aim at ensuring high-quality management. In this context, the management framework is implemented by means of different management models. According to the detailed description of Cornejo et al. [1], these models can be divided into two main categories: direct and indirect management. With regard to the direct management model, regular maintenance tasks are accomplished via comprehensive maintenance contracts and works. Special maintenance tasks cover pavement maintenance. Nowadays, 43% of the road network (30,502.12 km of carriageway) follows a "direct" management type, which means that the Public Administration carries out all necessary actions in order to assess the condition of road assets and to determine the works required for their proper maintenance. The indirect management model involves that regular and special maintenance tasks are outsourced by virtue of two different approaches: toll road concessions, and, more recently, first-generation highway concessions. With respect to the toll road model, the Public Administration delegates most management duties to the concessionaire, as users pay a toll to use the road. The second alternative is in accordance with the “Plan for the Upgrading of First-Generation Roads”. In this case, the Government outsources the maintenance of 1,994 km of carriageway to private companies, including pavement maintenance tasks, for a limited period of time, by means of a shadow toll system. In this case, the Government assumes the role of supervisor to ensure that these companies meet the service and quality standards set forth in the contract’s technical requirements. Henceforth, roads following a direct management model will be referred to as RCE. Shadow toll roads adhering to the “Plan for the Upgrading of First-Generation Roads” will be named A1G. Lengths and figures appearing in this paper allude to the length of carriageways.
