Stakeholders around Europe were asked to share their experiences with different materials and procedures for pothole repairs in a questionnaire. In a lot of cases, either materials or procedures were used which are not suitable for a durable pothole repair, possibly because no common regulations or requirements for materials exist in the different countries. Therefore, normal and new approaches which target the medium- or long-term repair of potholes have been studied. In a catalog of tests, evaluation methods and experiences according to existing European Standards have been compiled to give road agencies an overview of the possibilities for the repair of potholes. Furthermore, the testing of techniques and the use of material types from already existing trial sites have been used to determine properties of materials and their related laboratory tests which can, or should, be used to select the correct testing of materials for this purpose. Based on these results, a lifecycle cost analysis has been carried out and guidelines have been produced to select a repair technique and/or material with a durability corresponding to the estimated lifetime of the existing pavement.
