It was found that modifying harsh concrete with anion-active bitumen emulsion boosts the performance properties of roller compacted concrete pavement, namely: compressive strength (by 32% ...
The vast majority of bitumen is used in road construction, where it serves as a binder mixed with aggregate particles to create asphalt concrete. Its adhesive and cohesive properties provide a durable and water-resistant surface, making it an ideal material for road construction.
In this article, we talk about the different admixtures that you can use to enhance the strength of concrete and improve the project's durability.
Asphalt concretes are not only being used in the construction of roads for vehicles but are also being used in the construction of walkways, bike paths, parking lots, and driveways. Bitumen is mostly used as a binder for asphalt concrete. However, bitumen has been used in waterproofing and roofing materials [73,74]. The use of …
Under the same concentration regimes of the ternary bitumen composition, the maximum increase in compressive strength RD was achieved with the smallest size of bee-like structures of modified bitumen.
