The invention provides a stable regeneration method of cement fly-ash gravel base reclaimed material cement based on mortar content control. The stable regeneration method comprises the following steps: sampling and grading reclaimed materials; measuring the content of attached mortar and mortar agglomerate in the reclaimed materials; designing the proportioning ratio of the mixed materials; stirring and mixing the mixed materials; forming and curing a mixed material test piece and detecting the strength of the test piece. The regeneration method is simple and effective; the regeneration utilization rate of the cement fly-ash gravel base reclaimed materials can be greatly increased, the mechanical strength of the regenerated mixed materials is enhanced, and the application grade of the regenerated mixed materials in road bases can be increased.
