Abstract:
The performance and durability of asphalt pavements may suffer as a result of
bitumen drain down, which is the separation of bitumen from an asphalt mixture.
Numerous studies and investigations have been conducted on the elements that
influence drain down and the efficiency of fiber additives in reducing this problem.
The investigations covered in this abstract were aimed at determining the causes of
bitumen drain down and the results of adding fiber additions to asphalt mixtures. To
assess the results and comprehend the underlying mechanisms, an extensive literature
review was done. Pavement structures face a severe issue with bitumen drain-down.
In order to reduce the bitumen drain down, certain steps must be performed because
it weakens the structure. There have been numerous materials utilized, including
fiber, mineral fillers, and polymers. We employ conventional fibers of several types
in our research. The goal of this study is to compare the bitumen drain-down values
in each fiber reinforcement with the initial sample which is no fiber reinforcement
