一种水泥混凝土道面结构体系及其工程应用方法
By optimizing the airport's cement concrete pavement structure system, including a surface-enhanced cement concrete top layer, a green cement concrete bottom layer, an asphalt-based drainage functional layer, a crack-resistant cement-stabilized crushed stone base layer, and a deformation-coordinated granular cushion layer, the problem of insufficient pavement durability has been solved, achieving a long-life and high-performance pavement structure.

AI Technical Summary
The existing airport cement concrete pavement structure has insufficient durability and is prone to defects such as misalignment, broken slabs, surface peeling, pitting, insufficient anti-skid properties, exposed aggregate, and chipped edges and corners, leading to frequent maintenance and affecting operational safety and efficiency.
The cement concrete pavement system adopts a top-down structure, including a surface-enhanced cement concrete top layer, a green cement concrete bottom layer, an asphalt-based drainage functional layer, a crack-resistant cement-stabilized crushed stone base layer, a deformation-coordinated granular cushion layer, and a shallow reinforced pavement base. Each layer is optimized through material and thickness design to enhance its anti-freeze, anti-skid, and impact resistance.
It significantly extends the pavement's functional and structural lifespan to over 40 years, reduces maintenance costs, improves operational safety and efficiency, and avoids the high cost problem of single-layer high-performance concrete.
