BITUMEN RECOVERED FROM HIGHWAYS AND ITS USE IN RECYCLED MIXES

This paper presents the results of a study of bitumen reclaimed from highways by both hot and cold processes and an investigation of how to treat it for use as a binder for paving materials. The work was carried out against the background of current British practice and so includes the determination of penetration and softening point. In addition other parameters relevant to performance such as penetration index and stiffness were measured. It was found that all recovered bitumens meet the penetration and softening point requirements of BS 3690. In addition all blends of recovered bitumen with new bitumen or flux oil meet BS 3690. The tentative conclusion which can be drawn is that the bitumen in reclaimed asphalt, softened to a grade suitable for particular mix, will be a satisfactory binder for use in a highway pavement. This paper should be read in conjuction with the paper "Structural Properties of Recycled Mixes" by the author, published in "Highways and Transportation", March 1985, pp 8-12.
