Publisher's Synopsis
Rising volumes and loadings of road traffic have led to the development of new surfacing materials such as thin surfacings and stone mastic asphalt (SMA). Thin surfacings, used in layers with thicknesses between those of traditional wearing courses and veneer coats, provide, in principle, all the advantages of a surface dressing without the disadvantages of the aftercare service required for surface dressing. This report describes road trials to assess SMA as well as various categories of proprietary thin surface materials which are commonly available in the UK. The results were encouraging and several of the proprietary thin surfacings now have Departmental Type Approval for use on trunk roads and motorways in England.
