A recycled engineering plastic assembled pavement and its laying method

Abstract

The invention proposes a recycled engineering plastic assembled pavement based on a honeycomb structure and a paving method thereof, belonging to the technical field of road construction, which includes an assembled pavement assembled from a plurality of honeycomb recycled plastic panels, a honeycomb recycled plastic The panel includes a cover plate, a side plate, a honeycomb core plate and a bottom plate. The cover plate and the bottom plate are respectively arranged on the upper surface and the lower surface of the honeycomb core plate, and the side plates are arranged on the periphery of the honeycomb core plate. A honeycomb recycled plastic panel It is connected with an adjacent honeycomb recycled plastic panel through a side plate; the honeycomb recycled plastic panel is made of waste plastics, fillers, glass fibers, flame retardants, coupling agents and lubricants in proportions by mass. The raw material of the honeycomb recycled plastic panel is mainly waste plastic, and the waste plastic is used to prefabricate the honeycomb recycled plastic panel for road paving. The honeycomb recycled plastic panel has excellent mechanical properties and can better bear the load of the vehicle on the road.

Description

technical field [0001] The invention belongs to the technical field of road construction, and in particular relates to a recycled engineering plastic assembled road surface and a laying method thereof. Background technique [0002] The invention of plastics has greatly facilitated people's lives. Plastics can be seen everywhere in our daily life, but it takes a long time to degrade waste plastics, some even need 200-300 years, which affects the soil environment. Direct incineration of plastics will also affect the atmospheric environment. Therefore, how to recycle waste plastics and how to reduce the harm of waste plastics to the environment has always been a hot research topic. The application of recycled waste plastics to road pavement is also a concern of researchers in the field of road construction in recent years. focus. [0003] The development of my country's prefabricated roads is still in its infancy, and there are still many deficiencies, mainly in the following...

AI Technical Summary

Problems solved by technology

[0004] 1. When paving the existing prefabricated roads, it is necessary to lay a layer of cornerstone on the roadbed before installing the pavement panels, and the operation process is complicated;

[0005] 2. The existing prefabricated pavement panel is a solid cement concrete structure. The density of cement concrete is high, and the pavement panel is heavy. During the laying process, it is easy to generate a large shear stress, which leads to cracks in the bottom layer of the pavement panel and replaces the pavement. The integrity of the panel reduces the service life of the pavement panel;

[0006] 3. Cement concrete pavement panels are prone to cracks during use and require long-term maintenance, which affects the normal use of the road. At the same time, cement concrete pavement panels are prone to water accumulation on rainy days;

[0007] 4. Under the existing prefabricated pavement panels, there are optical cables, electric cables and other pipelines. During maintenance, it is necessary to dig out a large area of ​​the pavement panels for maintenance, and the maintenance takes a long time, which affects people's normal travel
