Description

However, this heating method has many disadvantages, which seriously restricts the efficient and environmentally-friendly development of bitumen regeneration technology.

[0003] Firstly, direct heating is easy to cause the volatilization of light components in bitumen, and even cause bitumen aging, thereby reducing the performance and service life of regenerated bitumen. This is because the direct contact of open flame or high-temperature gas with bitumen will destroy the original chemical structure of bitumen, damage its active ingredients, and further affect the adhesion and durability of bitumen.

[0004] Secondly, the traditional heating method usually has low heating efficiency and high energy consumption. Due to the uneven heat transfer in the heating process, a long heating time is often needed to reach the required temperature, which not only increases the energy consumption, but also prolongs the production cycle and reduces the production efficiency.
