The Highways Infrastructure is one of the most valuable asset owned by the public sector. Efficient operations of Highways have the success of national and local economies as well as the quality of life of the general public, dependent on it. Ensuring smooth traffic operations requires maintenance and improvements of the highest standard. This research investigates integration of Discrete Event Simulation (DES) and Value Stream mapping (VSM) to enhance the productivity of the delivery of road surfacing operations by achieving higher production rates and minimum road closure times. Research approach involved use of primary data, collected from direct observation, interviews, review of archival records and productivity databases. Based on this, process maps and value stream maps were developed, which were subsequently used to produce discrete event simulation models, for exploration of different optimisation scenarios.
