Problems solved by technology

These phenomena of excessive pursuit of development have caused a series of problems: the noise pollution caused by driving cars in the city, the air pollution caused by vehicle exhaust emissions are becoming more and more serious; traffic congestion has become the norm, and traffic accidents occur frequently; The phenomenon of living separation and pendulum traffic
[0004] However, there are still many deficiencies in the current slow-moving system: In terms of safety, cyclists and pedestrians are vulnerable groups in urban traffic safety, and are extremely vulnerable to injuries in traffic accidents; The unified planning and design ignores the aesthetics of the slow traffic system; in terms of humanities, the needs of pedestrians are not fully considered, and the principle of people-oriented is not reflected, and the walking comfort is low
Although this technical solution involves pavement materials for slow-moving roads, the pavement materials cannot absorb visible light during the day and emit light autonomously when the environment is dark

Abstract

The invention relates to a preparation method of a road paving material for a city slow-traffic system. The preparation method includes: mixing pebbles with the particle size being 1.0-1.2cm and polyhedron-particle-shaped self-luminous stone materials with the particle size being 1.0-1.2cm, and adding lignin and titanium dioxide; mixing pebbles with the particle size being 0.5-1.0cm, polyhedron-particle-shaped self-luminous stone materials with the particle size being 0.8-1cm and round-particle-shaped self-luminous stone materials with the particle size being 0.3-0.5cm, and adding lignin and titanium dioxide; mixing pebbles with the particle size being 0.3-0.5cm, polyhedron-particle-shaped self-luminous stone materials with the particle size being 0.5-0.8cm and round-particle-shaped self-luminous stone materials with the particle size being 0.1-0.3cm, and adding lignin and titanium dioxide; adding polyurethane and dibutyltin dilaurate. The paving material prepared by the method can absorb light in the daytime and emit light at night.

Description

technical field [0001] The invention belongs to the technical field of road and environmental engineering, and in particular relates to a method for preparing road pavement materials for urban slow-moving systems. The pavement materials prepared by the preparation method are suitable for urban greenways, sidewalks, and people (vehicles) in residential areas. Streets, parking lots, playgrounds, squares and other urban slow traffic system roads. Background technique [0002] The current urban development is inseparable from the "fast" direction. The urban population is growing rapidly, the pace of urban life is fast, the number of motor vehicles is increasing rapidly, and urban construction is developing rapidly. These phenomena of excessive pursuit of development have caused a series of problems: the noise pollution caused by driving cars in the city, the air pollution caused by vehicle exhaust emissions are becoming more and more serious; traffic congestion has become the no...
