INFLUENCE OF AGGREGATES ON THE FRICTIONAL PROPERTIES OF ASPHALT SURFACING MIXTURES

Friction between tires and pavement surfaces has assumed increased importance because of its relation to road safety. Several studies have been conducted to investigate the effect of aggregates on the frictional properties to assist the selection of appropriate aggregates for surfacing mixtures. This paper presents results of two interrelated research projects, which evaluated the influence of the aggregate type and their properties on surface friction. The research involved both laboratory investigations and field testing on trial sections. Seven typical aggregates (from five different quarries) were evaluated in a research project conducted by Norwegian University of Science and Technology (NTNU). A further nine types of aggregate from twelve different quarries are being considered in another project called SIV (Ruts in Road, 2001-2004), which focuses on rutting and friction problems with emphasis on the influence of the aggregates.
