AI Technical Summary
The structural strength between the base layer and the surface layer in existing gravel pavement structures is relatively weak, which affects the performance of the pavement. Furthermore, the high viscosity modified asphalt limits its application in specific environments.
The design employs a multi-layer structure, including a base layer, formwork support, rebar binding area, and concrete layer. The concrete layer is mixed with a dyeing dispersant, and the surface is sprinkled with colored gravel aggregate. It is then treated with a passivating agent and a transparent protective agent. Combined with mechanical electric brush cleaning and roller brushing of the transparent protective agent, a gravel pavement with high load-bearing capacity and anti-slip function is formed.
Gravel pavements with high load-bearing capacity and anti-skid properties are suitable for various environments, eliminating the dependence on modified asphalt and meeting the design requirements of different thematic environments.
