Asphalt modification equipment is a professional equipment used to modify ordinary asphalt.
1. Main components
It usually includes the following main parts:
1. Asphalt storage tank: used to store ordinary asphalt, generally with insulation function to prevent the temperature of asphalt from dropping too fast during storage and affecting subsequent processing.
2. Modifier addition system: responsible for accurately adding various modifiers (such as polymers, rubber powder, etc.) to asphalt in a certain proportion. This system usually includes metering devices, conveying devices, etc. to ensure that the amount of modifier added is controllable.
3. Mixing system: fully stir the asphalt with modifier added to make the modifier and asphalt evenly mixed. The design of the mixing system directly affects the quality of the modified asphalt. Generally, a strong mixer is used to ensure uniform mixing in a shorter time.
4. Heating system: In order to make the asphalt and modifier better blend, the mixture needs to be heated. The heating system usually uses fuel oil, gas or electric heating to ensure that the asphalt can reach the appropriate processing temperature.
5. Control system: monitor and control the operation of the entire equipment, including the setting and adjustment of parameters such as temperature, stirring speed, and modifier addition amount. The higher the intelligence of the control system, the easier the equipment is to operate, and the more guaranteed the production efficiency and product quality are.
2. Working principle
Ordinary asphalt is transported from the storage tank to the mixing container, and a certain amount of modifier is added to it through the modifier addition system. Then, the heating system is started to heat the mixture to a certain temperature, and the stirring system starts to work to fully stir and mix the asphalt and modifier. During the stirring process, the asphalt and the modifier undergo physical and chemical changes, which improves the performance of the asphalt. After a certain period of stirring and heating, a modified asphalt that meets the requirements is obtained.
3. Application field
It is widely used in engineering fields such as highway construction, airport runways, and parking lots. Modified asphalt has better high temperature stability, low temperature crack resistance and durability, which can improve the service life of the road surface and driving safety.
