Problems solved by technology

[0003] At present, in the construction process, poor concrete materials are generally used for road bases, and the strength of poor concrete is generally low, resulting in a weak pavement structure bearing capacity. If the strength of the pavement structure layer is increased by changing the material mix ratio, the road bearing capacity will be enhanced. will increase the cost of road construction accordingly
And in the process of road operation, due to the surge in traffic volume and increasing traffic load, the bearing capacity of the pavement structure is insufficient, and there are many early diseases, which seriously affect the durability of the pavement structure

Embodiment 1

[0051] figure 1 It is a structural schematic diagram of a pavement structure layer according to an embodiment of the present invention. like figure 1 As shown, the pavement structure layer can mainly include:

[0052] The constraint array 10 includes a plurality of constraint frames 11; in the construction process, a constraint frame 11 with constraint force can be placed on the working area of ​​the road surface to be paved such as soil foundation or base, and the constraint frame 11 can be selected from steel bars, geosynthetics, etc. Materials such as steel-plastic grid, glass fiber grid, plastic grid or geotextile that can provide binding force;

[0053] Road building materials 13 are filled inside each of the constraining frames 11, and the road building materials 13 and the constraining frames 11 are bonded together to form the pavement structural layer, and the road building materials 11 may include concrete prefabricated blocks , at least one of block stones, flak...

Embodiment 2

[0058] image 3 It is a structural schematic diagram of the pavement structure layer constraint frame in another embodiment of the present invention. like image 3 Shown (road construction materials in image 3 not shown), on the basis of the above embodiments, the constraining frame 11 may further include a bottom grid 113 and / or a top grid 115 connected to the side grid 111 .

[0059] Wherein, the shape of the bottom grid 113 may be approximately rectangular, the width may preferably be the width of the road, and the length may be adjusted according to construction requirements. During construction, the bottom mesh 113 can be laid on the road first, and then the side mesh 111 can be erected on the bottom mesh 113, and the intersecting parts of the two can be welded, hinged or bound together.

[0060] The material and shape of the top grid 115 can be the same as that of the bottom grid 113 to facilitate production and construction. During construction, after filling the s...

Embodiment 3

[0062] Figure 4 It is a structural schematic diagram of the constraining frame in the pavement structure layer of another embodiment of the present invention. and Figure 1 ~ Figure 3 The constraint frame 11 shown differs in that, as Figure 4 The shown constraining frame may be a cylindrical grid 117 parallel to the road surface. Wherein, the section of the cylindrical grid 117 perpendicular to the road surface can be square, rectangular or other shapes, Figure 4 The top surface of the cylindrical grid 117 shown is in an unconnected state. In the actual construction process, after road construction materials such as concrete prefabricated blocks, block stones or flakes are usually placed in the cylindrical grid 117, the cylindrical grid will be placed The tops of the cells 117 are connected, eg welded, hinged or tied together; adjacent cylindrical cells 117 may also be connected together. certainly, Figure 4 The connection position of the cylindrical grid 117 can also...

Abstract

The invention relates to a pavement structure layer and a paving method thereof. The pavement structure layer comprises a binding array and a road material, wherein the binding array comprises a plurality of binding frames; the binding frames are filled with the road material and integrally bonded with the road material to form the pavement structure layer; the road material comprises one or more of concrete precast blocks, block stone, rubble stone and concrete. Due to the adoption of the binding array consisting of the binding frames, binding force can be provided for the filled road material, and the formed pavement structure layer is high in bearing capacity, so that the bearing capacity of a pavement adopting the pavement structure layer can be increased and the service life of the pavement can be prolonged.

Description

technical field [0001] The invention relates to the technical field of road pavement, in particular to a pavement structural layer and a paving method thereof. Background technique [0002] A pavement structure may generally include a surface course, a base course, a subbase course, a cushion course, and a soil foundation. The surface layer of the asphalt pavement can also be divided into an upper layer, a middle layer and a lower layer. The surface course of cement concrete pavements is usually a concrete slab. [0003] At present, in the construction process, poor concrete materials are generally used for road bases, and the strength of poor concrete is generally low, resulting in a weak pavement structure bearing capacity. If the strength of the pavement structure layer is increased by changing the material mix ratio, the road bearing capacity will be enhanced. This will increase the cost of road construction accordingly. Moreover, in the process of road operation, due...
