Characteristics of Cast-in-Place Asphalt Mixtures
Pourable asphalt mixtures differ from other types in that they consist of high-content, high-viscosity asphalt, a high dosage of mineral powder, and sometimes fiber materials, all combined with an appropriate amount of aggregate.

Advantages of Cast-in-Place Asphalt Mixtures
Pour-in-place asphalt mixtures are dense, impermeable, highly durable, and exhibit excellent adhesion and viscoelastic properties. They have strong adaptability to deformation and show excellent compliance with the deformation of steel bridge decks. These mixtures feature a high mineral powder content, a high asphalt content, high mixing temperatures, and stringent technical requirements for raw materials. Their key advantages include: 1. They exhibit viscoelastic behavior and are insensitive to shock waves; 2. The binder is resistant to aging, ensuring superior durability; 3. They are both impermeable and non-absorbent, thus avoiding water damage; 4. They possess excellent resistance to low-temperature cracking.

Design of the Rotary Compaction Tester Control System
Modern industrial control is continuously evolving toward intelligence and automation. A growing number of automated production lines and flexible manufacturing systems have emerged, significantly boosting the application of intelligent controllers such as PLCs in system maintenance. At the same time, demands for on-site operability and maintainability are steadily increasing. Touch screens offer advantages such as simple operation, user-friendly interfaces, straightforward programming, excellent communication with PLCs, and strong anti-interference capabilities, all of which effectively meet these growing requirements. As a result, touch-screen technology is seeing increasingly widespread adoption in industrial applications.
