Asphaltum, identified by its CAS number 8052-42-4, is a fundamental material in the construction sector, particularly for its vital role in paving applications. Characterized by its black or dark-brown mass appearance, this substance is integral to building robust and long-lasting road surfaces. Understanding its properties, usage, and proper handling is crucial for its effective application.

The primary use of Asphaltum is as a binder in asphalt concrete, the mixture used for paving roads, driveways, and parking lots. Its consistency as a black or dark-brown mass is typical of bitumen, a petroleum-derived binder that provides asphalt its adhesive and cohesive strength. The melting point of Asphaltum, typically between 54°C and 173°C, is a critical parameter that determines its workability. This property allows the material to be heated to a pliable state, enabling it to be mixed with aggregates like stone, sand, and gravel at asphalt plants.

Further defining its suitability for paving are its thermal characteristics, including a boiling point exceeding 371°C and a flash point of 400°F. These high temperature values indicate significant thermal stability, meaning Asphaltum can withstand the elevated temperatures involved in asphalt production and laying without decomposing or becoming a safety hazard. This stability is crucial for ensuring the quality and consistency of the final paved surface. Standard packaging, often in 25KG drums, aids in its efficient transportation and handling on construction sites.

In the context of road paving, Asphaltum acts as the glue that holds the aggregate components together, forming a dense, durable, and flexible pavement. This composite material is designed to withstand the dynamic loads from vehicles and the environmental stresses from weather changes. The effectiveness of Asphaltum in this role is directly tied to its properties and the precision of the paving process. For professionals working with this material, understanding the 'asphaltum CAS 8052-42-4 properties' is key to successful project outcomes. Equally important is adhering to the recommended 'storage of asphaltum 8052-42-4' guidelines: it should be kept in a cool, dry, and well-ventilated location, with containers sealed tightly to preserve its quality and prevent contamination.

In summary, Asphaltum (CAS 8052-42-4) is a cornerstone material for the paving industry. Its characteristic appearance, specific melting point, boiling point, and flash point are all critical factors that enable its primary function as a binder in asphalt construction, ensuring the creation of resilient and functional road surfaces.
