Zusammenfassung: | The invention discloses a continuous pavement structure with a continuously paved cement-stabilized crushed gravel base layer. The continuous pavement structure comprises an asphalt surface layer, a glass fiber grating layer and a base layer which are paved from top to bottom, the base layer comprises a gravel upper base layer, a gravel lower base layer and a gravel subbase layer which are laid from top to bottom; cement is poured in the upper gravel base layer, the lower gravel base layer and the subgravel base layer in a layered mode. And the content of the cement is 3.2%-3.8%. The cement dosage of the gravel upper base layer, the gravel lower base layer and the gravel subbase layer is reduced, then the operation modes of temperature shrinkage and dry shrinkage reduction are adopted, the stability of the gravel base layers is stabilized through cement, the beneficial effect of being good in shrinkage resistance is achieved, and meanwhile pavement cracking is effectively prevented.
