The invention relates to a method for measuring trace metal content in asphalt with the atomic absorption spectrometry. The method includes the steps of 1), preparation of standard serial solutions, namely preparing the standard serial solutions of copper elements, manganese elements, zinc elements, nickel elements, iron elements, calcium elements, chromium elements, vanadium elements and barium elements; 2), establishment of an instrument method, namely a flame part; 3), establishment of an instrument method, namely a graphite part; 4), establishment of standard curves, namely establishing the atomic-absorption-spectrum standard curves of the copper elements, manganese elements, zinc elements, nickel elements, iron elements, calcium elements, chromium elements by adopting an atomic absorption spectrometer and establishing standard curves of the vanadium elements and barium elements by adopting a graphite atomic absorption spectrometer; 5), test of a sample to be tested. The method is systematic, accurate and high in repeatability.
