SEACAP 27: Mid-Term Pavement Condition Monitoring of the Rural Road Surfacing Trials (RRST). Technical Paper 1. Visual Condition Assessment of RRSR Trial Road Options.
The SEACAP 27 project was a logical extension of the SEACAP 1 research and was concerned primarily with the continued collection and analysis of pavement performance information from the RRST I and RRST II trial road sections. Mid-term pavement monitoring provides information on early performance and deterioration and is vital if the reasons for deterioration are to be recognised and understood. This is because once a pavement has failed it is often difficult to determine the original causes. Thus mid-term monitoring is an essential link in the analysis of performance which will only be completed following the future longer term monitoring.
This Technical Report provides an evaluation of the condition of the RRST monitoring sections based primarily on an analysis of the visual condition surveys undertaken up to and including those completed in July 2008. The survey completed in February 2009 has not been formally included in this evaluation, although a cross checks have been undertaken to ensure that the reported results from this survey are generally consistent with the conclusion of this report
