Light high-strength composite material pavement slab and quick connecting method thereof

The invention discloses a light high-strength composite material pavement slab and a quick connecting method thereof. The pavement slab comprises a sandwich plate, skins arranged on the two sides of the sandwich plate, and pavement slab sealing edges arranged on the edge part of the sandwich plate, wherein the sandwich plate is made of an ultra-light material containing a three-dimensional topological reinforcing structure, the light material is provided with a lattice reinforcing structure or a honeycomb reinforcing structure or a combined reinforcing structure, and gaps of the reinforcing structure are filled with foam materials; angular connecting blocks are arranged at the ends of two adjacent pavement slab sealing edges, the angular connecting blocks are fixedly connected with the adjacent pavement slab sealing edges, and the sandwich plate, the skins and the pavement slab sealing edges are bonded into a whole. The method can be used for quickly constructing temporary roads, temporary airports and tempor
