| Abstract: | The sulfur amount of fly ash has a substantial influence on the intensity and stability of road base course. Elicited from an engineering case, this paper discusses and analyzes the mechanism of road base course expansion cracks,intensity decrease, and final destruction caused by high sulfur content fly ash, which is testified by indoor and outdoor experimentations. And it is also given as a reference of others professionals. |
