A filler defined as that fraction of an inert mineral dust passing the 200-mesh sieve in a bituminous mixture can perform several functions. one function is that of filling voids in coarser aggregates, which increases the density, stability, and toughness of a conventional bituminous paving mixture. another, is the creation of a filler-asphalt mastic in which the particles of dust either may be individually coated with asphalt or are incorporated into the asphalt in mechanical and colloidal suspension. these forms of mastic are produced by special processes, such as cooking, atomized asphalt, and foamed asphalt. in paving mixtures the mastic serves as the cementing agent. the effect of fillers in conventional-type mixes is pronounced. abundance quantity of filler tends to increase stability, brittleness, and proclivity to cracking. insufficiency of filler tends to increase void content, lower stability, and soften the mix. in mastic mixes the quantity of filler used is not critical. at the point when filler particles are individually coated with thin films of asphalt, strong, stable, tough mixes may be prepared composed of 100 percent filler with 20 to 25 percent of asphalt. in mixes wherein the filler is in suspension in the asphalt (such as the hot liquid asphalt mastic mixes, guss asphalt, roofing, and waterproofing compounds) the filler-asphalt mastic is the cementing agent. the properties of the filler-asphalt mastic are influenced by the quantity of filler in suspension. an asphalt cement of 200 plus penetration containing 30 to 40 percent of filler will form a cementing agent or binder having a penetration of about 10. in any case, the asphalt cement itself still retains its original penetration.
