Resilient modulus of porous asphalt using oil palm fiber

Abstract

In recent years, the use of waste fibers has been developing in many ways to increase the performance properties of asphalt mixture. Efforts to create a green technology which is more environmentally friendly that can produce economic value is also a consideration in the utilization of waste materials. The research is aimed to evaluate the resilient modulus of porous asphalt using oil palm fiber (OPF). Five different percentages of fiber (1%, 2%, 3%, 4% and 5%) were used by weight of bitumen. Several lab tests, such as characteristics, asphalts characteristics, and resilient modulus were carried out to compare and quantify performance of OPF-modified porous asphalt. In general, the results of experiments show that oil palm fiber addition to porous asphalt gives significant effect for its properties.
