| Abstract: | Owing to the fact that both the temperature-contracting coefficient and the dry-shrinking coefficient of the cement-stabilized crushed stone bed are great, cracks are most like to occur in it. Various cracking causes of the cement-stabilized crushed stone bed are dealt with in the paper, with corresponding preventive measures, and treating methods for through cracks suggested. Finally, with the construction of the New Bai Yun Airport at Guangzhou as a practical example, the effects of those preventive measures adopted are described in the paper. |
