The effective mainstreaming and practical application of all the previous phases of RRSR trial road design and construction is dependant on a successful assessment of the performance of the trial roads within their specific road environments. The SEACAP 27 project was therefore a logical and necessary continuation of the RRSR programme and was concerned primarily with the collection and analysis of pavement performance information from RRST I and RRST II trial road sections constructed from mid 2005 to mid 2006. This mid-term pavement monitoring forms the link between the completed short term monitoring and future longer term monitoring. This project completion report describes the project including the contractual arrangements, the relationships with project partners and summarises the main activities and outputs from the project. It also directly addresses the technical issues raised in other project documents and applies them to the central project topics.
