Abstract：In order to improve the durability of assembled grooved pavement,assembled airports should be investigated for wear resistance of macroscopic grooved structures of cement concrete grooved pavement necessarily to obtain the optimal characteristic parameters of macroscopic grooved structures.A tire-as-sembled grooved pavement interaction simulation model is used to analyze pavement wear under aircraft impact taxiing.Wear tests of pavement specimens are conducted by using a steel wheel wear testing ma-chine,and pavement wear resistance is analyzed by using point cloud scanning technology.Through nu-merical simulations of the macro structural parameters of different groove surface features,the pavement wear volume and tire stress are obtained.Optimized macro structural feature parameters are derived.Based on the experimental tests and point cloud scanning data analysis,the relationship between different macro structural feature parameters of the grooves and the wear rate is revealed,leading to the determina-tion of the optimal macro structural feature parameters.The results show that the wear rate of the pave-ment with rectangular grooves is higher than that of the pavement with trapezoidal grooves.When the groove space of groove is between 35～40 mm,the width of groove is between 15～25 mm,the depth of groove is between 2～4 mm,and the chamfer of groove is at an angle of between 25°～60°,the pavement wear rate and tire stress are comparatively low,helping extend the service life of both the pavement and the tire.
