    This research addresses the challenge of linking paving and compaction given that they are mostly treated as detached activities, leading to a decrease in the quality of the compacted asphalt layer. The objective was to develop a support tool that can assist decision-making related to equipment allocation and compaction strategies to be followed, such that an asphalt layer- given the prevailing conditions at the construction site- can be compacted efficiently and uniformly within a limited time interval. A basic planning protocol was then developed based on variables such as asphalt cooling, paver characteristics, roller characteristics and road geometry. 12 road construction projects were monitored over a 3- month period. Empirical data on paver speed, roller speed and the number of roller passes served as input for the tool. The monitored projects were evaluated by calculating actual paver output and theoretical and actual roller output on an interval scale and checking whether the output rates were aligned to each other during the whole construction process. The results show that in most cases, paver output, roller output and the available time for compaction were not aligned. The theoretical concepts applied in this research and the developed support tool for decision making appear to be useful for planning and monitoring paving and compaction and for steering it towards a more uniform process. This may lead to an improvement in the quality of the final compacted asphalt layer.
