The objective of this paper is to present a case-study of a Dutch highway project involving repavement with porous asphalt in Kompaktasphalt technology. The aim of the survey is to assess how the organization of works, selection of materials and methods affects the project efficiency in terms of speed of works, and what are scale and reasons for disruptions of the workflow. Observation of the works and on-site measurements were taken to record organisation and method of repaving processes. The focus was on asphalt mix flows from the batching plant to the construction site, and related information flows. Digital cameras (one located in the batching plant, the other on the building site) and GPS systems were used to facilitate data collection. Process duration distributions were defined on the basis of numerous observations, providing insight into scale of expected disruptions to the flow of materials and input for the models. Rates of server utilization provide insight into the quality
of organization of the works, and may be the basis for comparisons with other projects, or with future project plans options.
