Strategic Investments for the Optimisation of Airfield Pavement Performance in Major Airports in the U.K.

摘要

Strategic asset management optimises the asset performance in the most cost-effective manner. To deliver the optimum investment solution, a decision support tool was developed to generate investment and maintenance plans over a 20-year period optimising the performance of airfield pavements. The strength of the model is to plan in advance strategic, targeted maintenance treatments or replacement at section level. This planned approach can generate capital savings arising from optimising construction costs, minimising operational disruption, and targeting appropriate treatments. This paper presents two case studies of two major airport airports in the U.K.: Heathrow Airport Limited (HAL) and Manchester Airport (MAN). In all cases, savings up to 50% on a 20-year maintenance plan have been identified. Also, this performance-targeted, airfield pavement asset replacement strategy derived from the DST has identified savings of CO_2 in the next 20-year capital investment period; the sustainable aspects of DST are not covered in this paper.
