In order to study permanent deformation of Expressway Asphalt Payment and the corresponding maintenance counter measures which have run away. In this paper, full thickness loading test of asphalt surface is used to analyze the cumulative run deformation capacity and residual bearing capacity of the existing pavement with different run depths and analyze the deformation layer of the core sample after loading and the test results after painting and curing. It is included that the peak rutting depth of existing pavement line to structural damage is 17.6 mm and the permanent rutting deformation depth is 27.3 mm. At the same time, the pavement maintenance counter measures and evaluation standard for permanent deformation of existing asphalt pavement are observed for the three rutting depth ranges.
