During their useful lives, (about 10 years for bituminous and 20 years for PCC), pavement surfaces are subjected to influences of various physical actions and chemical reactions that tend to break up or wear down the surfaces in various ways making them less durable and more expensive to maintain. However, safety through providing adequate skid resistance requires that some wear on a micro-scale be available to revive surface friction which is reduced by the continual scrubbing and polishing action of tires passing over the surfaces. Accordingly, compromises have to be made through incorporating in surface designs aggregates and textures that will resist excessive wear, but will undergo minor differential wear on a microscale. Good bonding of the materials comprising the bulk of the surface, the aggregates, by use of appropriate amounts and high quality of the cementing agents is necessary for maintaining both wear resistance and skid resistance.
