Embodiment 1

[0036] Embodiment one sees figure 1 Shown: This kind of subgrade built by using recycled aggregates of brick-concrete construction waste has a 180-800 mm thick regenerated inorganic binder stabilized material layer on the lower bearing layer 3, and a regenerated inorganic binder stabilized material layer is built on the regenerated inorganic binder stabilized material layer. Road surface layer 1, the road surface layer is a concrete surface layer, an asphalt mixture surface layer, or a road surface layer composed of oil-permeable, gravel, and intermediate layers. The recycled inorganic binder stabilized material layer is a recycled inorganic binder stabilized material layer 2 made of brick-concrete construction waste recycled aggregate particles mixed with ordinary aggregates and alkaline gelling powder, and the recycled inorganic binder stabilized material layer 2 It is a single structural layer laid by one material, and the material can be one of the following three ratios: ...

Embodiment 2

[0045] Embodiment two, see figure 2 As shown, the recycled inorganic binder stabilizing material layer 2 is divided into two layers: the lower layer 2.1 of the recycled inorganic binder stabilizing material and the upper layer 2.2 of the recycled inorganic binder stabilizing material. The thickness of each layer of the lower layer 2.1 of the recycled inorganic binder stabilized material and the upper layer 2.2 of the recycled inorganic binder stabilized material is preferably 180-200mm, the minimum compacted thickness is not less than 150mm, and the acceptance deflection value of the recycled inorganic binder stabilized material layer is generally less than 30 (0.01mm). The lower layer 2.1 of recycled inorganic binder stabilized material can be laid with brick-mixed recycled inorganic binder stabilized coarse aggregate, and the upper layer 2.2 of recycled inorganic binder stabilized material can be laid with brick-mixed recycled inorganic binder stabilized medium aggregate. ...

Embodiment 3

[0048] Embodiment three, see image 3 As shown, the recycled inorganic binder stabilized material layer 2 is divided into two parts: the lower layer 2.1 of the recycled inorganic binder stabilized material and the upper layer 2.2 of the recycled inorganic binder stabilized material. The lower layer 2.1 of the recycled inorganic binder stabilized material has a layer, and the recycled inorganic binder stabilized material Material The upper layer 2.2 consists of two layers. The thickness of each layer is preferably 180-200mm, the minimum compacted thickness is not less than 150mm, and the acceptance deflection value of the recycled inorganic binder stabilized material layer is generally not less than 25 (0.01mm). The lower layer 2.1 of the recycled inorganic binder stabilized material can be paved with brick-mixed recycled coarse inorganic binder stabilized material, and the two layers of the upper layer 2.2 of the recycled inorganic binder stabilized material can use brick-mixe...

Abstract

The invention relates to a pavement base course material prepared from brick mixed building rubbish regenerated aggregate and a construction method thereof. A regenerated inorganic binder stable material layer with the thickness of 180-800 mm is constructed above a lower bearing layer, and a road pavement layer is constructed above the regenerated inorganic binder stable material layer; the regenerated inorganic binder stable material layer is formed by mixing brick mixed building rubbish regenerated aggregate grains and common aggregate and base gelation power and is divided into one layer to four layers, and every small layer selects one of three mixture ratios. The invention adopts the brick mixed building rubbish regenerated aggregate as a main raw material. By applying the brick mixed building rubbish regenerated aggregate to pavement materials, the invention solves the problems of low utilization rate, narrow range of application, small application quantity and the like of the brick mixed building rubbish. The application performance of the pavement base course material not only can meet the prior standard and the practical application condition requirement of engineering, but also has relatively better durability and mechanical property by test comparison of freeze thawing, strength and the like.

Description

technical field [0001] The invention relates to a roadbed and a construction method thereof. Background technique [0002] In recent years, with the large-scale construction and improvement of social infrastructure, the renovation and demolition of original buildings has also increased, and the resulting large-scale construction waste disposal problem has become increasingly serious, and the current construction waste The treatment method is mainly to produce bricks and small blocks after direct backfilling or primary crushing. The backfill treatment method will increase the difficulty of the development and utilization of this area in the future, and as far as the Beijing area is concerned, the large-scale infrastructure construction has caused excessive exploitation of sand and stone resources for construction, resulting in the depletion of sand and stone resources. Therefore, to achieve The recycling of construction waste is of great significance to the sustainable devel...
