Method for enhancing layered structure of asphalt concrete by using carbon fiber intermediate

The invention relates to a layered structure design method of carbon fiber intermediate reinforced resin-based asphalt concrete. The preparation method comprises the following steps: step 1, carrying out oxidation modification treatment on carbon fibers; step 2, washing the carbon fiber obtained in the step 1 to be neutral and drying; step 3, preparing a 1 wt% Y-aminopropyl triethyl silane coupling agent; 4, putting the carbon fibers obtained in the step 2 into a coupling agent for 4 hours, washing with deionized water until the pH value is constant, and drying at 80 DEG C for 24 hours; 5, uniformly coating the carbon fiber obtained in the step 4 with an absolute ethyl alcohol mixed solution of modified phenolic resin, flaky graphite, carbon powder and nitrile rubber, and drying; 6, uniformly mixing the carbon fibers obtained in the step 4 with a certain proportion of phenolic resin, graphite and an absolute ethyl alcohol solution of carbon powder, and drying; and 7, sequentially filling the material and the
