[0002] Asphalt is a mixture of hydrocarbons of different molecular weights and their non-metallic derivatives. It has waterproof, moisture-proof and anti-corrosion effects. The mixture formed by adding asphalt to mineral materials can be used to pave asphalt pavement, making the paved road have the advantages of easy maintenance and low noise.

[0003] A Chinese patent with publication number CN221371726U discloses a crack-resistant asphalt pavement structure for highways. The key points of its technical solution are: it includes a roadbed, a first cushion layer fixedly connected to the upper end of the roadbed, a second cushion layer fixedly connected to the upper end of the first cushion layer, a connecting layer fixedly connected to the upper end of the second cushion layer, a first base layer fixedly connected to the upper end of the connecting layer, a second base layer fixedly connected to the upper end of the first base layer, and a first surface layer fixedly connected to the upper end of the second base layer. This crack-resistant asphalt pavement structure is constructed by compacting the roadbed and then laying the cushion layer. First, a first cushion layer composed of crushed stone and limestone is laid. When water flows into the interior of the highway through the surface layer, it will be absorbed by the first cushion layer to prevent water from entering the roadbed and damaging it. A second cushion layer of waterproof material is laid on the first cushion layer as the main waterproofing material.

[0004] Existing related technologies often have the following defects: the highway asphalt pavement structure in the existing technology has reinforcing ribs inside, and the reinforcing ribs are relatively strong. When the asphalt pavement expands or contracts due to heat or cold, it affects the overall stretching or contraction of the asphalt pavement, resulting in poor crack resistance of the asphalt pavement.
