With the improvement of living standards and the application of the concept of "people -oriented" in road traffic, people pay more and more attention to the harmony of roads and the environment. Traditional black asphalt pavement and white cement pavement can no longer meet the needs of modern road traffic development.So, can we put on the colorful "coat" to the road surface and change its monotonous color? Many scholars at home and abroad have conducted in -depth research on this issue, and the colored asphalt pavement came into being.Texas tells you the benefits and functions of color asphalt pavement:
1. The function of color pavement
It is mainly used for urban roads, attractions, parks, squares, etc.And have the following functions:
(1) Beautify the traffic environment and cities.Color asphalt equipment manufacturers said that laying color pavement is a direct means to change the road traffic environment.The colorful color of colorful roads can create a warm and pleasant atmosphere, giving people a beautiful enjoyment.
(2) It is helpful for driving.Because of its rich colors and high recognition, it can induce traffic and reduce traffic accidents for wet road sections, ramp exports, emergency parking bands, special channels, etc.
(3) Relieve the increasingly serious city "hot island effect".Traditional black asphalt pavele can absorb more solar radiation in summer due to high thermal absorption and low reflectivity, increase the temperature of the pavement, and affect the ambient temperature to varying degrees.The application of color pavement can greatly reduce the sunshine rate, increase the reflectance of the pavement, thereby reducing the temperature of the pavement and alleviating the "hot island effect".
Second, color pavement technology and its application
Depending on the color source and construction process, the color pavement can be divided into the following types: asphalt concrete pavement, rare pulp section, semi -flexible pavement, flower pavement and color pavement.The color pavement is a new type of road surface. It is formed by applying a number of agglomerations of polymer resin adhesives and a variety of particle size.It has been widely used in developed and regional and mainland China.
The color of changing the asphalt pavement With the continuous advancement of my countrys urbanization process and the construction of beautiful countryside in recent years, many colorful roads have appeared in various towns. It has the following characteristics:
1. convenient and fast: spray directly on the original road, construction is fast, no large equipment is required.
2. Simple processes: Fast open traffic, traffic will be open for 2 hours.
3. Economic and environmental protection: One spraying for molding, which can be used for 3-5 years without fading, low cost, and environmental protection.
Asphalt pavement color changes can be used for color pavement spraying agents and construction methods:
1. Clean the pavement to ensure that the pavement is clean and dry, without water, and repair damaged places in advance.
2. Stir the pavement chromatis evenly with a mixer.
