Continuous paving type cement stabilized crushed gravel base continuous intersection pavement structure
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. The purposes of guaranteeing the quality standard, effectively shortening the construction period and relieving the traffic pressure are achieved, and therefore the purposes of efficiently saving investment cost, saving energy and shortening the construction period are achieved.
本发明公开一种连铺式水泥稳定碎砾石基层不断交路面结构，包括由上至下铺设的沥青面层，玻纤格栅层和基层；基层包括由上至下铺设的碎石上基层、砾石下基层和砾石底基层；碎石上基层、砾石下基层和砾石底基层内分层浇筑有水泥；水泥含量均为3.2％‑3.8％。本申请通过降低碎石上基层、砾石下基层和砾石底基层的水泥剂量，再采取温度收缩和干缩降低的操作形式，通过水泥稳定碎石基层稳定性、具有抗收缩性能好的优点，同时有效防止路面开裂。达到既保证质量标准又能有效减少施工周期，缓解交通压力的目的，从而实现高效节省投资费用、节约能源、节约工期的目的。
