Abstract:

Synthetic aggregates are produced by the thermal or chemical processing of natural or manmade materials. The physical properties of these aggregates vary considerably, depending on raw material and method of processing, and their properties are often considerably different from those of the natural aggregates on which current test methods and specifications are based. Skid resistance is primarily a function of the microtexture and macrotexture of the pavement surface. The physical properties of the individual aggregatee particles determine level of microtexture and resistance to wear and polishing, which are important properties in the retention of skid resistance. Various methods of producing synthetic aggregates for skid-resistant surfaces are reviewed. Emphasis is placed on processing methods, available raw materials, and properties of the processed aggregate. The mechanisms by which different classes of aggregates develop microtexture and resistance to wear and polishing are discussed. It is concluded that each of these materials develops skid resistance and resistance to wear and polishing in a different way and that this should be reflected in designs and specifications. Many potentially acceptable synthetic aggregates are energy and capital intensive. /Author/
