The research object is the main landing gear tires of A320 and the assembled slab,based on the theory of energy dissipation and the basic principles of tribology,the energy dissipation equation between tire and pavement is es-tablished,and the quantitative relationship between pavement macrostructural characterization parameters of pavement and frictional dissipation can be obtained.Then,dynamic simulation model of tire-slab interaction is es-tablished using ABAQUS.Finally,the optimal constructional characteristic parameters(groove depth,groove width and groove chamfer)of assembled grooved pavement can be obtained through simulation experiment.The re-sults show that assembled slab with groove width of 30 mm,groove depth of 2 mm and groove chamfer of 45°can significantly enhance the skid resistance of the pavement and has excellent frictional dissipation property,also provide a larger contact area with the tires,leading to better traction performance,which can effectively enhance the durability of assembled slab.
