Mix Design and Road Performance of Strong Interlocked Skeleton Close-Grained Lime-Flyash Stabilized Aggregate
To improve the road performance of lime-flyash stabilized aggregate (LFSA), mix design method for skeleton close-grained LFSA is proposed by the method of multi-level filling theory and particle interference theory. Road performance of it is verified by indoor test. The results show that the designed LFSA, with the mix design method of strong interlocked skeleton close-grained (SISC) LFSA proposed in this article, has good road performance. Compared with LFSA of the gradation of Chinese technical specification for construction of highway asphalt pavements (CS gradation), the late strength of LFSA of SISC gradation increases 18%, the temperature shrinkage coefficient and dry shrinkage coefficient respectively increase by 15% and 45%, the scour resistance increases by 20%. Therefore, the SISC LFSA has a broad application prospect.
