Abstract

The invention relates to a light-emitting permeable concrete road based on recycled aggregate and a construction method thereof. The light-emitting permeable concrete road comprises a permeable cushion layer (1), a permeable base layer (2) and a light-emitting permeable surface layer (3) which are sequentially laid and pressed from bottom to top, and the surface of the light-emitting permeable surface layer (3) is coated with a light-emitting permeable surface layer sealant (4); the permeable cushion layer (1) comprises pressed ceramsite (5) and low-quality recycled aggregate (6) which are laid from bottom to top; the permeable base layer (2) is first high-quality recycled aggregate permeable concrete (9); and the light-emitting permeable surface layer (3) comprises light-emitting permeable concrete (7) and second high-quality recycled aggregate permeable concrete (8). Compared with the prior art, the light-emitting permeable concrete road has the advantages of energy saving, environmental protection, good permeable effect, high durability, low cost, high luminous intensity, long luminous time, attractive appearance, multiple functions and the like; compared with the prior art, theconstruction method has the advantages of simplicity, high construction efficiency and the like.

Description

technical field [0001] The invention relates to the field of roads, in particular to a luminous permeable concrete road based on recycled aggregates and a construction method thereof. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization, the construction industry has developed by leaps and bounds in my country. At the same time, the amount of construction waste generated has repeatedly set records. However, the current treatment of construction waste is mainly to simply landfill, which has caused a great burden on the ecological environment. As the main component of construction waste, waste concrete can be recycled and used rationally, which can not only recycle limited natural resources, but also solve the problem of environmental pollution caused by landfill treatment. [0003] In recent years, with the continuous implementation of national energy conservation and emission reduction policies and the contin...
