Abstract
Road maintenance outsourcing is now the foremost strategy by which road authorities procure maintenance works. Despite growing application of road maintenance outsourcing, there are conflicting estimates on the effectiveness of road maintenance outsourcing and shortage of appropriate models to align over optimistic expectations of road authorities from road maintenance outsourcing with substantiated benefits. This paper investigates the efficacy of road maintenance outsourcing. In this paper, the different variants of road maintenance outsourcing and road maintenance works are evaluated with a SWOT analysis and a comprehensive literature review respectively. In addition, a road maintenance outsourcing alignment model based on a decision tree and Balance Score Card is proposed and illustrated with a Nigerian trunk road network authority as a case study. The result of the SWOT analysis and comprehensive literature review establishes fresh insight into road maintenance outsourcing dynamics. The presented road maintenance outsourcing alignment model provides adequate pathways that could assist road authorities identify the most appropriate road maintenance outsourcing variant for road maintenance procurement. In addition it aligns actual benefits and expectations of road maintenance outsourcing and facilitates development of SMART metrics for effective assessment of road maintenance outsourcing. The proposed model is applicable across other infrastructures.

Objectives for adopting road maintenance outsourcing differs across road authorities, various classes of road maintenance works and competing variants of road maintenance outsourcing exists, and shortage of appropriate models to manage road authorities over optimistic expectations from road maintenance outsourcing increase the degree of complexity, multidimensionality and robustness of the issue
The evaluation of existing road maintenance outsourcing variants above shows that the interest on implementing road maintenance outsourcing is still growing
Summary
The traditional way of procuring road maintenance based on insourcing has failed to match the goals of cutting maintenance expenses and enhancing services on road networks (Stenbeck 2004; Porter 2006). This has spurred a paradigm shift on how road maintenance is being procured (Porter 2001). Road maintenance outsourcing is the partial or total transfer of the management of road networks to the private sector with a view to inspire innovation, cut cost and improve efficiency (Tomanelli 2003). There is a need for fresh insight into the road maintenance outsourcing process
