摘　　要：通过室内试验及试验路段验证,从二灰碎石结构强度形成、强度再生机理、外掺剂对再生性规律影响等进行理论分析,得出二灰碎石基层早期强度破坏后,具有一定程度再生的科学结论。Through laboratory experiments and scale-up test on lime-flyash-macadam as paving material for the stabilized soil base course, a scientific conclusion is drawn that the pavement of lime-flyash-macadam material to a certain extent have restorability after the destruction of its early period strength. And the conclusion is supported by the theoretical analysis of the strength formation, restoration mechanism of the strength, and the influences of admixtures on the restorability.
