    • PURPOSE: A method and a system for measuring the compaction density of asphalt pavement using an auto-level, and a paving method of an asphalt road using the same are provided to accurately measure the compaction density of asphalt pavement using a non-destructive method. CONSTITUTION: A method for measuring the compaction density of asphalt pavement using an auto-level is as follows. Before road pavement, the surface position of a base(B) is measured using an auto-level and a vertical ruler. A road pavement material(P) is spread on the base. A sample(S) is extracted from the spread road pavement material, and the weight of the sample is measured. The spread road pavement material is compacted, and the compacted surface position of the road pavement material is measured using the auto-level and the vertical ruler. The compaction volume of the sample is calculated using the measured surface position and compacted thickness of the sample. The compaction density of the sample is calculated from the compaction volume and weight of the sample.
