Cement-based colored composite pavement material and construction method thereof

Abstract

The invention provides a cement-based colored composite pavement material and a construction method thereof, and relates to the technical field of pavement paving. A colored composite pavement which is good in bonding property, resistant to abrasion, free of pollution, resistant to skidding and resistant to aging can be obtained; the composite pavement material is one or more of a bonding layer material, a leveling layer material, a surface layer material and a sealing layer material which include cement-based bonding emulsions correspondingly; the cement-based bonding emulsions include cementand aqueous solutions, and the aqueous solutions include polymers, water, dispersing agents and stabilizing agents; and construction is carried out through a process for coating a bonding layer, a leveling layer, a material surface layer and a colored sealing layer. The technical scheme provided by the invention is suitable for the paving process of the colored pavement.

Description

【Technical Field】 [0001] The invention relates to the technical field of pavement paving, in particular to a cement-based color composite pavement material and a construction method. 【Background technique】 [0002] The two commonly used colored pavement materials are divided into hot-mix colored asphalt mixture and two-component polymer mixed colored ceramsite. [0003] Among them, the hot-mix colored asphalt mixture can be completed by using the existing asphalt hot-mixing station and paving and rolling equipment. It has the characteristics of high mechanization and fast construction speed, and can realize the characteristics of large-scale construction, but because of the large amount of stone itself It is black or brown, and the color is all realized by a thin layer of colored asphalt oil film, which is often partly worn off within a year, revealing the black stone, which looks dirty, which greatly affects the appearance of the city; at the same time, the high temperature Poor ...

Problems solved by technology

[0003] Among them, the hot-mix colored asphalt mixture can be completed by using the existing asphalt hot-mixing station and paving and rolling equipment. It has the characteristics of high degree of mechanization and fast construction speed, and can realize the characteristics of large-scale construction. It is black or brown, and the color is all realized by a thin layer of colored asphalt oil film, which is often partially worn off within a year, exposing the black stone, which looks dirty and greatly affects the appearance of the city; at the same time, the high temperature Poor stability and poor durability

[0004] Colored ceramsite mixed with two-component polymers is mostly formed by manual coating & spreading or manual mixing & paving. It has the characteristics of high manual use and slow construction speed, and is not suitable for large-scale use.

The cement is a thermosetting material. Once cracked in winter, the crack cannot be healed in summer. After rainwater enters, the pavement is prone to hollowing out and peeling off.

In order to ensure the ease of construction, the two-component polymer contains a large amount of organic solvents. After the colored pavement is paved, it will gradually evaporate from the pavement, which is the main contributor to smog——VOC. Affect air quality; in addition, two-component polymer colored pavement materials have poor aging resistance and short service life
