According to the design of AC10 fined grained asphalt concrete used as stress absorbing layer,this paper proposes the related design method based on equilibrium of pavement performance.This method adopts the asphalt-aggregate ratio under closest compact condition as lower limit and that at the inflexion of run-off loss ratio in Schellenberg Binder Drainage Test as upper limit to finally determine the optimum asphalt-aggregate ratio according to the optimum pavement performance.Through the verification of a substantial highway project in Guangxi province,it achieves good application result.
