A thin layer asphalt to meet local government demands

The quest to provide a suitable cost effective, thin surface continues where an asphalt finish is specified. Yet the top few millimetres of a bituminous road surface are subjected to extremes of temperature, tyre stress, abrasion, oxidation and subsequent brittleness and so thin lift surfaces are vulnerable. Therefore those few millimetres on the surface must consist of the best aggregate and binder available. It remains that thin surfacing (less than 25mm thick) has great potential as it can provide both preventive and corrective maintenance and be cost effective when used on a sound pavement at the appropriate time. Over the last 15 years there has been great interest in thin surfacing such as micro surfacing and Novachip, which provide shape correction. Novachip also provided macro surface texture for skid resistance and tyre noise reduction. However, neither process has provided a complete answer and both require purpose built equipment.
