Asphaltum, scientifically identified by its CAS number 8052-42-4, is a pivotal material in the construction industry, primarily recognized for its extensive use in paving applications. This compound, typically appearing as a black or dark-brown mass, possesses a unique combination of physical and thermal properties that are essential for constructing durable and functional road surfaces. A thorough understanding of Asphaltum is crucial for professionals in civil engineering and construction.

The physical appearance of Asphaltum as a black or dark-brown mass is characteristic of bitumen, a viscous liquid derived from petroleum that serves as the primary binder in asphalt mixtures. The material's melting point, ranging from 54°C to 173°C, is a key property that dictates its workability. This temperature range allows Asphaltum to be heated and mixed with mineral aggregates, such as crushed stone, sand, and gravel, to form asphalt concrete. This process, carried out in specialized asphalt plants, yields a cohesive material ready for paving.

Further defining its utility are its thermal characteristics: a boiling point exceeding 371°C and a flash point of 400°F. These high temperature values indicate that Asphaltum possesses considerable thermal stability, which is vital during the heating, mixing, and laying stages of asphalt pavement construction. This stability ensures that the binder maintains its structural integrity and does not degrade prematurely, contributing to the overall quality and safety of the paving process. Asphaltum is commonly supplied in 25KG drums, a packaging standard that facilitates its logistical handling and deployment on construction sites.

The principal application of Asphaltum lies in road paving. Acting as the binder, it envelops and adheres the aggregate particles, forming a strong, flexible, and weather-resistant pavement surface. This composition allows roads to withstand the significant stresses imposed by traffic loads and environmental factors. The durability and performance of asphalt pavements are directly correlated with the quality of the Asphaltum used and the precision of the manufacturing and laying processes. For those looking to purchase or utilize this material, understanding the 'asphaltum CAS 8052-42-4 properties' is essential. Proper 'storage of asphaltum 8052-42-4' is equally important; it requires a cool, dry, and well-ventilated environment, with containers kept tightly sealed to maintain its quality and prevent contamination.

In conclusion, Asphaltum (CAS 8052-42-4) plays a fundamental role in the creation of modern road infrastructure. Its distinctive appearance, coupled with its crucial melting point, boiling point, and flash point, makes it an ideal binder for asphalt paving, contributing significantly to the longevity and functionality of our transportation networks.
