Marshall stability test has been used in Japan as the mix design method for hot mix asphalt since 1961 when this method was adopted in the "Manual for Asphalt Pavement ". Recently, this method has been considered to be an emprical one that can especially design a durable mixture which is rut resistant. We, therefore, propose a rational mix design method whose procedure is to calculate the voids in mineral aggregate from the aggregate gradation then add the necessary asphalt content to get an appropriate air voids ratio of the mixture. The required material properties are checked in both this calculation and in the actual compacted specimens..
