Abstract:A uniform and continuous paving process is a prerequisite for a good quality asphalt layer. This in turn requires proper work preparation and organization of the paving and compaction process. However, currently the selection of working practises and equipment allocation is largely baded on experience, while the choices made will have a major impact on the final quality of the asphalt layer. This resarch project had aimed to set up a method which can assist planners in making decisions regarding roller equipment allocation and in generating operational compaction strategies. A method has been drafted for aligning the paver output with the roller output/capacity, also taking the available time for compaction into account. This method consists of 6 steps and can be used for the planning or the paving and compaction process. In the planning phase, one shoud decide whether the paver output or the roller capacity will be the restrictive factor. In conclusion: the drafted method seems an appropriate method for planning the paving and compaction process. However, the planning method is based on single average operational values, while during the actual paving and compaction process, variation in operational valaues can be expected. Good average results over the entire road section do not immediately imply good results on each subsection of the road. Therefore, when striving after a consistent process, one has not only to plan the process, but also to monitor the process on regular interval scale. Future research effort should be devoted to the monitoring of the paving and compaction process.
