1. This method specifies the preparation of asphalt mixture specimens in the laboratory using the wheel rolling method to test physical and mechanical properties.

2. Suitable for forming plate-shaped specimens (300 mm long, 300 mm wide, 50-100 mm thick). These can be further cut into prismatic specimens or used for coring. The density of formed specimens meets the Marshall standard (100% ± 1%).

3. Specimen thickness is selected based on aggregate size:

• Max aggregate size ≤ 19 mm: 50 mm thick plate mold.
• Max aggregate size ≥ 26.5 mm: 80-100 mm thick plate mold.

For ordinary asphalt mixtures, 50mm thick specimens can be compacted according to standard cycles. However, for specialized mixtures like SMA, S-type compacted mixtures, or modified asphalt with high viscosity, the required number of compaction cycles can be determined through integrated testing to ensure the best gradation density.
