Double-layer laminated type prefabricated pavement and construction method thereof

Abstract

The invention discloses a double-layer laminated type prefabricated pavement and a construction method thereof. According to the pavement, the advantages of a traditional cement and asphalt pavement are retained, the limitation of a traditional fabricated road on transportation and connection is broken through, and the standardized operation efficiency and technology level of pavement paving are greatly improved while the drainage performance of the pavement is enhanced. Waste plastic modified asphalt and recycled building materials are adopted, so that the concept of environment-friendly development is reflected; and through prefabrication and standardized assembly, the road construction cost can be lowered, the construction efficiency is improved, and interference of the traditional construction process on residents along the line is reduced. Considerable economic and social benefits are expected to be produced, development of a novel road paving structure and material is promoted, and development of the road engineering industry is promoted.

Description

technical field [0001] The invention relates to the field of assembled road surfaces, in particular to a double-layer laminated prefabricated assembled road surface and a construction method thereof. Background technique [0002] Prefabricated cement concrete pavement was developed by developed countries as early as more than ten years ago, and it has developed to a certain scale; in recent years, domestic research on prefabricated cement concrete pavement has also begun, but due to problems such as connection, transportation, and cost, it has not yet been realized. promote. [0003] The existing carpet pavement prefabricated a flexible and rollable asphalt pavement pavement layer, which was laid and installed on site like a carpet, and was bonded to the surface of the underlying layer by microwave heating, thereby quickly completing the construction. However, the limitation of carpet pavement is that the thickness of pavement is thin at one time, and there are still many p...

Problems solved by technology

[0004] In order to solve the above technical problems, the present invention proposes a double-layer laminated prefabricated pavement and its construction method based on the concept of ecological sustainability. The present invention solves the joint connection problem of the prefabricated panels during the assembly process by using structural design and assembly methods. The use of permeable plastic waste to modify asphalt not only retains the advantages of traditional cement concrete pavement and asphalt pavement, but also enhances the drainage performance of the pavement and greatly improves the standardization operation efficiency and technological level of pavement paving.

[0005] The present invention first uses the structural design of the prefabricated road slab to solve the problems of difficult connection of the joints generated in the splicing process of the prefabricated road slab and the difficulty in transportation of the prefabricated asphalt panel; That is, it is connected with the concrete base to form a prefabricated slab with good integrity, so as to improve the transportation efficiency and safety with the concrete base as the carrier; finally, the network connection formed by the longitudinal dowel bar and the horizontal tie bar is used to cooperate with on-site pouring and fast setting Type self-compacting concrete tightly connects the prefabricated slab structural units to form a high-strength whole, and then uses asphalt cement material to treat the joints between the prefabricated slab units, finally forming a flat and stable road surface
