| Abstract: |
| Aimed at the distress characteristics and rehabilitation requirement of airport pavement,systematic indexes and standards to evaluate storable asphalt mixture(SAM) properties,including looseness,compaction strength and water stability,are presented and the key factors such as property and content of asphalt,gradation of aggregate,content of additive,affecting SAM properties are analyzed based on the review of current research.A new kind of SAM is successfully designed and the corresponding practical technology is also introduced.The properties of SAM are demonstrated to be high quality by experiments and practical application,as a result,it can be widely used for rapid repair of airport pavement. |
