The quality standard of stadium asphalt concrete base

The stadium asphalt concrete layer is used as the base layer of the plastic surface layer of sports track and field venues, not the surface layer of the road engineering, and has many aspects of quality requirements. It can refer to the standards of the urban road engineering, but it is due to the requirements of the competition project. The location and frequency of inspection items are also slightly different. For the asphalt concrete base quality standards and testing methods, see the table below.

Note: 1. On-site sampling, as far as possible in the construction of excavated sections;

2. "Items" means the long jump runway, the high jump run-up area, and the pole bounce runway for the field event;

3. "Compactness" refers to the ratio of % to optimal density;

4. Except for "field sampling", all other points are randomly sampled.
