Asset management aims at improving the overall performance of asset- intensive industries by making and executing systematic and highest value decisions about the use and care of assets. This requires an intensive collaboration between professionals from different fields with a diversity of technical and social backgrounds. To assist companies and agencies in improving their asset management performance, maturity models can be used. In this paper we describe two applications of the Infrastructure Management Maturity Matrix (IM³). The IM³ consists of five maturity levels on the vertical axis (ad hoc, repeatable, standard, managed, optimal), and seven asset management dimensions on the horizontal axis (information management, internal coordination, external coordination, market approach, risk management, processes & roles, and culture & leadership). We present the results of two maturity checks performed at the Dutch National Highway Agency Rijkswaterstaat in 2011 and 2012. The results show the effects of the measures within RWS during this period. In the conclusion we reflect on the findings and possible future developments for RWS. We also discuss the potential impact of infrastructure maturity models for the professionalization of asset intensive organizations in general. Keywords: organizational growth, maturity model, road infrastructure, asset management maturity.
