The invention relates to the technical field of simulation of asphalt pavement rolling construction forming working conditions, in particular to an indoor simulation test method for asphalt pavement rolling. The method comprises the following steps: S1, preparing a test piece and fixing the test piece and a test mold on a test mold base; S2, setting working parameters of equipment; S3, starting the equipment to enable a pressure head to vibrate and roll back and forth on the surface of the test piece; S4, turning off the equipment, and acquiring density data on the test piece acquired by a nuclear-free density instrument; S5, judging whether the compaction uniformity meets the requirement or not by adopting mathematical statistics according to the density data, if the compaction uniformitymeets the requirement, carrying out S6, and if the compaction uniformity does not meet the requirement, carrying out the S3; and S6, taking out the test piece. According to the method, the density distribution condition of t
