Colored asphalt road materials are used in bus lanes, landscape roads, tourist roads, sidewalks, bicycle lanes, park roads, community roads, parking lots , used in airport runway slides and other places, it can effectively beautify the environment and divide traffic sections. Welcome to call: Liang Yi, mixing of hot-mixed colored asphalt concrete
, mixing method of hot-mixed colored asphalt concrete The technical requirements are basically the same as those of ordinary asphalt concrete.
Before producing colored asphalt concrete, the mixing tank should be cleaned, and the cement transportation pipeline should be set up separately to prevent the original black asphalt from being contaminated.
In order not to affect the quality of bright asphalt, before construction and mixing, the storage temperature should be controlled at -℃ when the storage days are less than 3 days, and the storage temperature should be controlled at -℃ or normal temperature when the storage days are greater than 3 days. When cooling and hardening to normal temperature and reheating with a burner, in order to prevent the cement from being locally heated, please use interval heating until half of the stored cement is dissolved. (For example: heating up every hour, extinguishing fire every hour).
The construction temperature of colored asphalt binder should be determined by measuring the viscosity-temperature curve under ℃ and ℃ conditions. In the absence of viscosity-temperature curve data, you can refer to the following ranges for selection: -Ⅰ Colored asphalt binder heating temperature ~ ℃, stone heating temperature ~ ℃, mixing temperature ~ ℃, discharging temperature ~ ℃, paving temperature not lower than ℃, initial The pressing temperature is 3~℃, and the final rolling temperature should not be lower than ℃. - The heating temperature of colored asphalt binder is ~℃, the heating temperature of stone is ~℃, the mixing temperature is ~℃, the discharging temperature is ~℃, the paving temperature is not lower than ℃, the initial pressing temperature is ~℃, and the final rolling temperature is not lower than ℃.
In order to make the pigment evenly distributed, the mixing time should be reasonably determined. The mixing time is generally longer than that of ordinary asphalt concrete.
Strictly control the mixing temperature and mixing time. The difference in mixing temperature of each plate of materials is less than ℃, and the difference in mixing time is less than 3.
2. Construction of cold-mix colored asphalt
Cold-mix colored asphalt is also called cold-paved colored asphalt and cold-patched colored asphalt. This kind of cold-mix colored asphalt pavement can be constructed without heating. Cold-mix colored asphalt The price is much more expensive than hot-mixed colored asphalt, and the construction of this material relies entirely on labor, so the construction cost is relatively expensive. The selling point of cold patching is that it is easy to operate and does not require as large a machinery as hot patching. It also has relatively loose requirements on the environment, traffic control and surface treatment. First, draw a cordon to enclose the area that needs to be repaired, then clean the road surface to remove all foreign debris (soil, gravel, sand, etc.), sweep it with a broom, and then use a hair dryer to blow away the dust, sand, etc. and dry the road surface thoroughly. Then spray the colored asphalt mixture
After cleaning, according to the owner's requirements, if you want to retain the original markings, use tape of a specific size to protect the markings, arrows, text, etc. To protect the curb stones, clean them , greening is not polluted, etc., it is necessary to use a baffle to cover the edge of the spray boom to prevent pollution caused by mist fine materials splashed under strong pressure.
Use an artificially adjustable speed motor and a stirring blade to stir each barrel of asphalt emulsion, stir it evenly, and then add emery at a constant speed. According to different road conditions, the proportion of sand can range from the least without sand to the most added emery (paper cup at room temperature, no more than one pound at most). After adding, set the mixing speed to the fastest setting and keep stirring at high speed for minutes. , let the mixture be mixed thoroughly, and let the asphalt emulsion fully coat every grain of silica sand
. There are two methods of construction:
Direct spraying by machine (put curing agent), (recommended for heavy traffic),
Manual pushing and scraping method (put curing agent and emery), (recommended for light traffic such as sidewalks, bicycle lanes, etc.)
Machine direct spraying: add the mixture to the spraying equipment container at normal temperature, and pass it through the pipe Flow into the spray gun and spray evenly
After spraying or scraping, be sure to remove the tape quickly to avoid sticking to the road
After the construction is completed, it can be opened to traffic
