Problems solved by technology

[0002] At present, the pavement paving boards used in urban buildings, including roadway bricks and sidewalk bricks, all have many problems such as low strength, easy damage, rough surface, etc., resulting in the construction of a new urban road surface, only three or two years It had to be refurbished again, which cost a lot of urban construction costs and caused a lot of waste of manpower and material resources.
[0003] At the same time, with the rapid development of the construction industry, there is a lot of waste concrete left over. If it is not used, it will cause a lot of waste and is not conducive to sustainable development.
[0004] At present, there are few studies on how to use waste concrete materials into pavement slabs, mainly because the pavement slabs made of waste concrete have poor impact resistance and water seepage resistance.

Embodiment 1

[0072] Embodiment 1: Regenerated pavement pavement, including base and surface layer, and the components and corresponding parts by weight included in base layer and surface layer are as shown in Table 1, in the admixture adopted in base layer and surface layer The components and their corresponding parts by weight are shown in Table 2, and the recycled pavement pavement board is prepared through the following steps:

[0073] S1, fully mix water, polycarboxylate superplasticizer, citric acid, sodium gluconate, triethanolamine, and potassium sulfate to obtain the first mixture;

[0074] S2, adding the cellulose ether and the thickener to the first mixture obtained in step S1, and fully mixing to obtain the admixture;

[0075] S3, uniformly mix cement, fly ash (first-class fly ash), regenerated sand, regenerated coarse aggregate, and regenerated micropowder to form a second mixture, then add admixtures and water, and fully mix to obtain a base layer mixture;

[0076] S4, fully ...

Embodiment 2-5

[0080] Embodiment 2-5: Regenerated pavement board, the difference with embodiment 1 is that the components and the corresponding parts by weight thereof included in the base layer and the surface layer (except additives) are as shown in Table 1, the base layer and the surface layer The components in the additives used in the layer and their corresponding parts by weight are shown in Table 2.

[0081] In table 1 embodiment 1-5, face layer and basic layer (except admixture) comprise components and parts by weight thereof

[0082]

[0083] Components and parts by weight of the admixture in the surface layer and the base layer in the table 2 embodiment 1-5

[0084]

Embodiment 6

[0085] Embodiment 6: Regenerated pavement board, the difference from Embodiment 1 is that the modified resin is polyvinyl acetal modified phenolic resin.

Abstract

The invention discloses a recycled pavement paving board and a manufacturing technology thereof. The recycled pavement paving board comprises a base layer and a surface layer, wherein the base layer comprises the following components in parts by weight: 20-22 parts of cement, 4-6 parts of fly ash, 25-40 parts of reclaimed sand, 21-26 parts of recycled coarse aggregates, 0.1-0.5 part of a recycledfine powder, 0.2-0.4 part of an admixture and 8-10 parts of water; the surface layer comprises the following components in parts by weight: 25-30 parts of cement, 5-8 parts of fly ash, 10-15 parts ofa quartz powder, 33-51 parts of medium sand, 0.2-0.5 part of modified resin, 1-1.5 parts of a waterproof powder, 0.5-1 part of cellulose, 0.4-0.6 part of the admixture and 6-9 parts of water; and therecycled fine powder is prepared by grinding at least one of recycled concrete, recycled bricks, waste sintered red bricks, waste stone materials and waste ceramic. The recycled pavement paving boardhas the advantages of low production cost, good impact resistance, and good water and pollutant resistance.

Description

technical field [0001] The invention relates to the technical field of pavement pavement, and more specifically relates to a regenerated pavement pavement and its manufacturing process. Background technique [0002] At present, the pavement paving boards used in urban buildings, including roadway bricks and sidewalk bricks, all have many problems such as low strength, easy damage, rough surface, etc., resulting in the construction of a new urban road surface, only three or two years It had to be refurbished again, and as a result, a lot of urban construction costs were spent, resulting in a lot of waste of manpower and material resources. [0003] At the same time, with the rapid development of the construction industry, there is a lot of waste concrete left over. If it is not utilized, it will cause a lot of waste and is not conducive to sustainable development. [0004] At present, there are few studies on how to use waste concrete materials into pavement slabs, mainly be...
