Problems solved by technology

In 2017, my country produced more than 2 billion tons of construction waste, of which the highest content of waste concrete accounted for about 40%. Crushing and disposing of it into recycled aggregate and then making recycled concrete is the main direction of resource utilization. Waste concrete in most developed countries The resource utilization rate can reach more than 90%, but in our country, despite the development of this industry for more than ten years, its resource utilization rate is still less than 10%. The waste may also cause secondary pollution
At night, however, these roads are often poorly lit

Embodiment 1

[0086] The components in the base material are measured by weight and then stirred and mixed to obtain a semi-dry base material, wherein the base material includes the following components by weight: 150 parts of cement, 20 parts of construction waste recycled micropowder, construction 600 parts of recycled coarse aggregate from garbage, 300 parts of recycled fine aggregate from construction waste, 80 parts of water, and 0 parts of water reducing agent. Then pave the grassroots mixture on the road and solidify it as the grassroots. The strength grade of the solidified grassroots is C30, and the thickness of the solidified grassroots is 200mm.

[0087] Stir and mix the components in the surface layer material in parts by weight to obtain a semi-dry surface layer mixture, wherein the surface layer material includes the following components in parts by weight: 150 parts of white cement, 10 parts of coloring powder 300 parts of recycled fine aggregate from construction waste, 80 p...

Embodiment 2

[0090] Stir and mix the components in the base material according to parts by weight to obtain a semi-dry base material mixture, wherein the base material includes the following components by parts by weight: 210 parts of cement, 60 parts of recycled micropowder of construction waste, construction 800 parts of recycled coarse aggregate from garbage, 500 parts of recycled fine aggregate from construction waste, 120 parts of water, and 5 parts of water reducing agent. Then pave the grassroots mixture on the road and solidify it as the grassroots. The strength grade of the solidified grassroots is C20, and the thickness of the solidified grassroots is 200mm.

[0091] Stir and mix the components in the surface layer material in parts by weight to obtain a semi-dry surface layer mixture, wherein the surface layer material includes the following components in parts by weight: 210 parts of white cement, 60 parts of coloring powder 500 parts of recycled fine aggregate from constructio...

Embodiment 3

[0094] The components in the base material are measured by weight and then stirred and mixed to obtain a semi-dry base mixture, wherein the base material includes the following components by weight: 210 parts of cement, 20 parts of construction waste recycled micropowder, construction 600 parts of recycled coarse aggregate from garbage, 300 parts of recycled fine aggregate from construction waste, 100 parts of water, and 3 parts of water reducing agent. Then pave the grassroots mixture on the road and solidify it as the grassroots. The strength grade of the solidified grassroots is C25, and the thickness of the solidified grassroots is 200mm.

Abstract

The present invention provides a luminous pavement material, which includes a surface material and a base material in sequence from top to bottom, wherein the base material includes the following components in parts by weight: 120-240 parts of cement; 10 parts of recycled micropowder from construction waste ‑70 parts; 500‑900 parts of recycled coarse aggregate from construction waste; 200‑600 parts in recycled fine aggregate from construction waste; 60‑140 parts in water; The following components: 120-240 parts of white cement; ≤80 parts of coloring powder; 200-600 parts of recycled fine aggregate from construction waste; 60-140 parts of water; ≤6 parts of water reducing agent. The present invention further provides a luminescent road surface. The invention provides a luminous pavement and a preparation method thereof. Construction waste is used to make a luminous art road. Luminous aggregates and brick aggregates can be inlaid according to a certain pattern. After being polished, it has an artistic effect, and the appreciation effect is better at night.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a luminescent pavement and a preparation method thereof, in particular to a luminescent artistic road pavement made of construction waste and a preparation method thereof. Background technique [0002] my country is still in the peak period of infrastructure construction, and the demand for building materials and the generation of construction waste are huge. In 2017, my country produced more than 2 billion tons of construction waste, of which the highest content of waste concrete accounted for about 40%. Crushing and disposing of it into recycled aggregate and then making recycled concrete is the main direction of resource utilization. Waste concrete in most developed countries The resource utilization rate can reach more than 90%, but in our country, despite the development of this industry for more than ten years, its resource utilization rate is still less than 10%.
