Bitümlü

Bitümlü is a Turkish adjective that translates to "bituminous" in English. It refers to materials derived from or containing bitumen. Bitumen is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. It is a key component in asphalt and is naturally found in deposits like the La Brea Tar Pits.

In construction, bitümlü materials are primarily used in road building and roofing. Bitümlü asphalt, also known as asphalt concrete, is the most common material for paving roads worldwide. It is a mixture of bitumen, aggregate (such as gravel and sand), and fillers. This combination provides a durable and flexible surface that can withstand heavy traffic and varying weather conditions. The bitumen acts as a binder, holding the aggregate particles together.

Bitümlü roofing membranes are another significant application. These are flexible sheets made of a carrier material, typically polyester or fiberglass, saturated and coated with bitumen. They are often used for flat or low-sloped roofs to provide waterproofing. Multiple layers of bitümlü membranes are usually applied to create a robust and watertight barrier. The material's adhesive properties ensure a strong bond between layers and to the roof substrate. The term "bitümlü" can also be used more broadly to describe anything that has the characteristics or properties of bitumen, such as a sticky or tar-like consistency.
