Embodiment

[0027] The plain soil base is a natural subgrade with a compaction coefficient of 93%, and the surface is a flat structure.

[0028] The crushed stone cushion layer 2 uses crushed stone or cement concrete fragments produced in the process of urban demolition, renovation, and new construction, and is screened with a standard aperture sieve. The thickness of the stone cushion is not less than 200mm, and the compaction coefficient is 95%.

[0029] The fine sand leveling layer 3 uses fine sand, which means that the gravel content in the sand is not more than 25%, and the sand whose particle size is greater than 0.5 mm exceeds 50% of the total mass. Then dope silica fume in the fine sand, where SiO in silica fume 2 The purity is not less than 80%, and the proportion of silica fume in the fine sand leveling layer 3 is 10% to 15%. It is required that after the fine sand leveling layer 3 is laid, the levelness of the upper surface of the layer should not be greater than 10mm, and th...

Abstract

The invention discloses a colored water permeable integral pavement and a construction technology, and belongs to the technical field of ground materials and construction. The colored water permeable integral pavement comprises a plain soil base layer, a crushed stone bedding layer, a fine sand leveling layer, an original color water permeable layer, and a colored water permeable layer, wherein the plain soil base layer is positioned at the lowermost layer, and the crushed stone bedding layer, the fine sand leveling layer, the original color water permeable layer, and the colored water permeable layer are sequentially arranged on the plain soil base layer from bottom to top. The colored water permeable integral pavement has the advantages that the crushed stone bedding layer is made of building crushed stone and concrete crushed stone which are obtained by replacing of urban buildings, so that the resource is saved, and the environment is protected; the characteristics of colorfulness, economy and practicality, high compressive strength, high water permeable rate, freezing and heat resistance, no pollution, no radiation, no dust flying, high applicability and high construction speed are realized; the colored water permeable integral pavement can be widely applied to the road places of squares, pedestrians, scene avenues, parks, schools, supermarkets, residential districts, parking lots and the like, so that the application range is wide.

Description

【Technical field】 [0001] The invention belongs to the technical field of ground materials and construction, and relates to a pavement construction process, in particular to a colored permeable integral pavement and a construction process. 【Background technique】 [0002] With the process of urbanization in our country, a large number of abandoned building rubble and concrete blocks are produced in the process of urban construction. Due to the low reuse rate of urban construction waste, they are piled up in the suburban junctions, which adversely affect the production and life of local residents and cause serious pollution. The environment is also not conducive to the development of the city. At present, in the construction of urban roads and floors, only the quality and service life are generally paid attention to, and little attention is paid to the ecological functions of urban roads and floors. Utilize the construction gravel and concrete fragments generated in the proces...
