Abstract
This chapter deals with the first attempt to derive a scientific, revolutionary, hot mix asphalt design method. The full rutting equation was derived as a function of the damage wheel pass number (Nd) in the previous paper by Huh. Since Nd is hard to measure, the single stroke breakdown energy (W1d), is disclosed to replace Nd. By using this W1d, new performance equations are proposed as a function of the W1d. The effectiveness of the new linear performance equation derived is experimentally validated. These performance equations in the form of master equations could constitute a scientific, rigorous, hot mix asphalt design theory. Since the formulation of master equations requires much effort and time, a simple design variable representing master equations is proposed as a design variable. This is an important discovery in this paper. Comparison of the suggested variable (W1d) among various asphalt mixes can predict both rutting and fatigue cracking simultaneously. It is hoped that this noble HMA design method can be a promising alternative for currently available empirical methods like Marshall, Gyratory Compactor, Indirect Tensile, BMD, etc. to obtain a better design value.
