Bitumipõhised

Bitumipõhised is an Estonian term that translates to "bitumen-based" in English. It refers to materials or products that use bitumen as a primary component or binder. Bitumen itself is a sticky, black, highly viscous liquid or semi-solid form of petroleum, often found in natural deposits or as a residue from petroleum refining.

Bitumen-based materials are widely used in various industries, most notably in road construction and roofing. In road building, bitumen acts as the binder that holds together aggregates such as gravel, sand, and crushed stone to form asphalt concrete, the most common material for paving roads. Its adhesive properties and resistance to water make it an effective choice for creating durable and flexible road surfaces.

In the roofing industry, bitumen is used to create waterproof membranes. These membranes, often reinforced with materials like fiberglass or polyester, are applied to flat or low-slope roofs to protect buildings from water damage. Bitumen's flexibility allows it to accommodate structural movements and temperature fluctuations without cracking.

Beyond construction, bitumen-based products can also be found in applications like waterproofing for foundations, protective coatings for metals, and even in some sealants and adhesives. The specific properties of bitumen, such as its waterproofing capabilities, adhesion, and plasticity, make it a versatile material for a range of industrial and construction purposes. The term "bitumipõhised" therefore encompasses a broad category of products defined by the presence and function of bitumen within their composition.
