Problems solved by technology

[0003] However, when the stirring equipment is stirring during the addition process, it is necessary to ensure that the temperature is not lower than 170°C and the stirring time is not lower than 7 hours, which makes the production preparation process and construction process long and complicated, which virtually increases the production cost and reduces the cost. Production and construction benefits are not suitable for the current economic society

specific Embodiment approach

[0026] A production process for colored asphalt roads. The production process mainly includes the following steps:

[0027] Step 1: Prepare materials; prepare aggregate, decolorized asphalt oil and toner according to the proportions. According to the different road temperature and environment, the mass ratio of aggregate, decolorized asphalt oil and toner is aggregate: decolorized asphalt oil: toner =30-35:2-3:1-2, the said aggregates are rolled crushed stones with rich edges and corners, hard texture, and similar cubic particles. According to the size of the particle size, they are divided into large particle size aggregate and medium particle size Aggregates and small particle size aggregates; the particle size of the large particle size aggregate is 5-10 mm, the medium particle size aggregate is 3-5 mm, and the small particle size aggregate is less than 3 mm.

[0028] Step 2: Heat the aggregate; use a mixing plant to heat the aggregate, stir and heat the aggregate to between 180...

Abstract

The invention relates to colored asphalt, particularly to a colored asphalt road applicable to various environments and a construction process thereof. The construction process comprises the following steps: preparing materials; heating aggregates; feeding color powder; producing colored asphalt; discharging and detecting. The colored asphalt road prepared by adopting the production process and the construction process is good in road application performance and good in high temperature stability, water damage resistance and durability at different temperatures and in different external environments, has no phenomenon such as deformation, dropping of the asphalt and the like, has good binding property with a basic layer, has bright and durable color, is not faded, can resist the high temperature of 77 DEG C and low temperature of -23 DEG C and is fast in construction period, convenient and rapid to produce, fast to construct, high in efficiency and capable of effectively reducing the traffic delay caused by the construction.

Description

Technical field [0001] The invention relates to a colored asphalt, in particular to a colored asphalt road suitable for various environments and its construction process. Background technique [0002] Colored asphalt, also known as color cement, is a kind of road construction material. It is widely used in slow-moving systems such as greenways, bicycle lanes, garden landscape roads, etc., and can also be used in bus lanes, intersections, expressway service areas There are currently two types of colored asphalt for heavy-duty traffic pavements: the first is a colorless binder with toner. The colorless binder can be obtained by decolorizing the asphalt, or it can be prepared from light-colored polymers such as petroleum resin. The other is obtained by direct modification of asphalt. This kind of cement has the characteristics of strong anti-aging ability of asphalt, and the color is brown-red. At present, the first type is common on pavement, but the colorless asphalt is produced b...
