The invention discloses a method for processing a precast cold laid asphaltic concrete material, which comprises the following steps of: (1) heating and mixing asphalt, graded broken stone and a mineral powder mixed material in a batching and mixing plant to form an asphaltic concrete mixed material; (2) adopting a mould to mould the asphaltic concrete mixed material in a thermal state into sheets which are convenient to splice and have the thickness of 2-9cm, and reducing to normal temperature; and (3) packaging, loading, and transporting the sheets at normal temperature to construction field, arranging and splicing the sheets in the field, heating, and rolling to achieve good density. The processing method makes more work such as mixing the asphaltic concrete material and primarily rolling and forming performed in a factory, and can achieve specialized and industrial production.
