THE USE OF A DESIGNED FOAMED BITUMEN STABILISED RAP IN AN URBAN HIGH STREET

The paper describes an analytical design approach and performance based specification used with a roadway refurbishment in Scotland. This approach was taken as the roadbase used was a foamed bitumen stabilized RAP. In the refurbishment the mixture was fully compacted and production variables had only a limited impact on material performance. The most significant factor influencing material performance was found to be material moisture content. It was suggested that the load spreading capability of such stabilized RAP mixtures can be compared to conventional hot applied bitumen mixtures through the use of a single equivalence factor. The data from this work seems to suggest this is not the case and the use of a single factor should be used with caution.
