bituumenipõhiseid

Bituumenipõhiseid refers to materials or products that use bitumen as their primary binding agent. Bitumen itself is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. It is commonly found in natural deposits or as a byproduct of petroleum refining. Its key properties include impermeability to water and excellent adhesive qualities, making it a valuable component in various applications.

The most widespread use of bitumen-based materials is in road construction. Asphalt concrete, a mixture of bitumen, aggregate (such as gravel and sand), and fillers, forms the durable surface of roads and highways. Bitumen binds the aggregate particles together, creating a cohesive and resilient pavement that can withstand heavy traffic and weather conditions. Other road applications include chip seals and slurry seals, which also utilize bitumen for surface treatment and repair.

Beyond road construction, bitumen-based products find use in roofing. Bitumen-saturated felts and membranes are commonly employed to create waterproof layers on flat or low-sloped roofs. These materials offer excellent protection against water infiltration and contribute to the longevity of building structures. Additionally, bitumen is used in sealants and coatings for various construction and industrial purposes, providing a protective barrier against moisture and corrosion. The versatility of bitumen's binding and waterproofing capabilities makes bitumen-based materials essential in many sectors.
