Abstract

A laboratory procedure is devised to evaluate the polishing tendencies of aggregates The design of the polishing machine is described. The size of aggregate particles were tested for their influence on the system. The average skid number for a material plotted against the corresponding traffic measured by revolutions gives a hyperbolic curve. A computer program gives the best fitting hyperbolic for each set of data points. The method gives a convenient quantitative evaluation of ultimate polish potential of an aggregate.
