Basic Components and Precautions for Use of the Asphalt Softening Point Tester
The asphalt softening point tester features a benchtop design that is both rational, innovative, and aesthetically pleasing, and it is easy to operate. The beaker is made of high-temperature-resistant glass, and the specifications and dimensions of the heating rate, steel ball positioning ring, and steel balls all comply with the requirements stipulated by the relevant standards.

Thermal Stability of Cast-in-Place Asphalt Mixtures
Pouring-type asphalt mixture is a type of asphalt concrete classified according to its construction process. It features a suspended dense structure and is characterized by a high content of fine aggregates, a high proportion of mineral powder, and a relatively high asphalt content. Pouring-type asphalt concrete is impermeable, resistant to freeze-thaw cycles, oil-resistant, and age-resistant. It also exhibits excellent performance in resisting low-temperature cracking and fatigue cracking. Due to its higher asphalt content, pouring-type asphalt concrete is prone to rutting under high-temperature conditions. Because pouring-type asphalt mixtures differ significantly from conventional asphalt mixtures—being produced through prolonged high-temperature mixing of high-asphalt-content, high-viscosity asphalt and large quantities of mineral powder—the design process requires careful consideration.

The Harm of Asphalt in Pouring-Type Asphalt Mixtures to Human Health
Acridine: Acridine is irritating to both skin and mucous membranes. Its dust particles and gases can easily trigger sneezing, and contact with the skin may cause itching and a burning sensation.

Analyze the functional modules of the rotary compactor.
Sensors: These are categorized into pressure sensors, displacement sensors, angle sensors, limit switches, and others, which respectively collect data on pressure, displacement of the pushrod, rotation angle of the turntable, and whether the pushrod has exceeded its limit.
