Kiviainesmassa

Kiviainesmassa refers to a mixture of mineral aggregates and a binder, typically asphalt or cement. In the context of road construction, it commonly denotes asphalt concrete, a composite material used for paving roads, parking lots, and other surfaces. This material is produced by mixing hot asphalt binder with carefully graded aggregate materials such as crushed stone, gravel, and sand. The proportions of these components are critical to achieving the desired performance characteristics, including strength, durability, and resistance to deformation. Kiviainesmassa is laid down hot and then compacted to form a dense, smooth surface.

In a broader geological or civil engineering sense, kiviainesmassa can also refer to cement-based composite materials, such as concrete or mortar, where aggregates like sand and gravel are bound together by cement paste. The properties of kiviainesmassa are influenced by the type and size of aggregates used, the type and amount of binder, and the manufacturing process. These materials are fundamental to modern construction, providing structural support and durable surfaces for a wide range of applications. The term emphasizes the aggregate component of the composite material.
