As an important building material, asphalt plays a key role in large-scale construction such as roads, airport runways, parking lots, etc. It can not only prevent road potholes, but also enhance the wear resistance and water resistance of the road. For the use of asphalt, in addition to the laying of regular, softening and dissolution are also one of the inevitable important steps in the construction process of asphalt. So, what is the fastest dissolution of asphalt? The following small series to give you a summary of several commonly used asphalt softening methods, I hope to help you.

1. Fuel oil softening

fuel oil, as a common solvent, is widely used in construction. It can not only help asphalt softening and shorten asphalt softening time, but also has relatively low cost and relatively simple operation. The use of fuel softening need to pay attention to fire prevention, avoid the use of peculiar smell of fuel, to prevent pollution to the environment.

2. thermal melting softening

thermal melting softening is a more common way of softening, it uses the characteristics of high temperature to turn asphalt into a liquid, can quickly soften asphalt. In the process of thermal melting, we need to pay attention to the control of temperature to avoid safety hazards such as explosion caused by high temperature.

3. Solvent Softening

Solvent softening is a relatively safe and effective way to soften asphalt. There are many kinds of solvents on the market, and the choice is relatively high. Accurate selection of solvents can improve the softening effect and efficiency, while shortening the construction time and cost.

In short, in the construction process, the softening and dissolution of asphalt is a very important task. Different softening methods have their own advantages and disadvantages. We need to choose the appropriate method according to the situation, strictly control the softening temperature and liquid, and take measures such as fire and explosion prevention to avoid safety accidents.
