Problems solved by technology

[0003] At present, prefabricated pavement is mainly used on landscape roads, residential roads, sidewalks and other non-traffic lanes, and has a single function. The main reason is that when prefabricated pavement is used on motor vehicle lanes, it is easily broken, and partial damage will affect the overall use.
The existing prefabricated pavement cannot meet the requirements of high-grade highways with drainage requirements

Embodiment 1

[0056] see figure 1 with figure 2 , the present embodiment provides a pavement prefabricated block 100 and an asphalt pavement prefabricated part formed by assembling a plurality of pavement prefabricated blocks 100 .

[0057] figure 1 Only three structural schematic diagrams of pavement prefabricated blocks 100 are shown in . From left to right: pavement prefabricated block 100 with interlocking protrusions 110 and interlocking concave parts 120 at both ends, pavement prefabricated block 100 with only one end of interlocking concave part 120 and only one end with interlocking Prefabricated pavement blocks 100 with protrusions 110 . These three types of pavement prefabricated blocks 100 are all provided with drainage holes 130, and the drainage holes 130 are vertically distributed in space, and two layers of drainage holes 130 are distributed up and down on a front end surface, and each layer is provided with 3 drainage holes in parallel, and the hole diameters are the sam...

Embodiment 2

[0075] This embodiment provides a pavement prefabricated block 100, refer to image 3 As shown, the pavement prefabricated block 100 includes a lower prefabricated block containing drainage holes 130 and an upper prefabricated block without drainage holes 130, and the lower prefabricated block is embedded with reinforcing strips 140 along the height direction, and the reinforcing strips 140 connect the lower prefabricated blocks and the upper precast block; the porosity of the upper precast block is 18%.

[0076] During preparation, the lower prefabricated block is first formed, and at the same time, the reinforcing bar 140 is pre-embedded in the lower prefabricated block, and then the upper prefabricated block is poured. The reinforcing bar 140 can be steel or chemical material. In this embodiment, the reinforcing bar 140 is made of steel.

[0077] In order to prevent the hidden danger of the durability of the prefabricated block, the prefabricated block is set to use a mixtu...

Abstract

The invention provides a prefabricated pavement material, a pavement prefabricated block, an asphalt pavement prefabricated part and a construction method thereof, and relates to the technical field of pavement prefabricated parts. The prefabricated pavement material is composed of specific graded graded crushed stone and cementing material. The graded crushed stone is scientifically and rationally designed to ensure that the prefabricated pavement composite material has sufficient pores, which not only realizes internal drainage, but also Noise from the road surface is also reduced. The graded crushed stones are connected together by cement, so that the compressive strength and splitting strength of the prefabricated pavement material meet the requirements of driving. The asphalt pavement prefabricated parts assembled by multiple pavement prefabricated blocks can be used for high-grade highway and bridge deck pavement, which broadens the function of the prefabricated pavement. The pavement prefabricated block can reduce the harm to workers caused by the harmful gas of hot asphalt paving, and at the same time save the construction and curing time of cement mixture.

Description

technical field [0001] The invention relates to the technical field of pavement prefabricated parts, in particular to a prefabricated pavement material, a pavement prefabricated block, an asphalt pavement prefabricated part and a construction method thereof. Background technique [0002] Existing prefabricated pavements are mainly divided into two types, one is asphalt mixture prefabricated pavement, and the other is cement concrete prefabricated pavement. Among them, the prefabricated asphalt pavement uses asphalt concrete blocks prefabricated by asphalt, stone materials, and other additives. The prefabricated asphalt pavement can be designed into different shapes and assembled to form, similar to the existing asphalt pavement. The cement concrete prefabricated pavement uses concrete blocks prefabricated by cement mortar, stone materials, and additives. The cement concrete prefabricated pavement can be designed into different shapes, and then assembled and assembled, simila...
