降噪型路面（LNAP）目前在我国的应用尚处于起步阶段，配合比设计方法和技术要求等还有待完善。文中从 LNAP降噪机理和效果的几个关键因素，包括空隙率、粒径、级配、厚度、沥青类型等，在参照国内外开级配沥青混合料设计方法调研的基础上，通过反复调试，提出了 LNAP13的混合料设计方法及标准。

The low-noise asphalt pavement(LNAP)is still at an initial stage at present in China,so the mix design method and technical requirements need to be improved.In this paper,based on several key factors of LNAP's mechanism and effect of noise reduction,including porosity,particle size,gra-dation,thickness,asphalt type,mix design method and technical index of LNAP1 3 is proposed by re-peating debugging based on investigation of domestic and overseas open-graded asphalt mixture design method.
