Analysis of Physical and Microstructural Properties on Parit Nipah Peat Particles as Sustainable Asphalt Modifier

Abstract

Innovations were conducted continuously to create sustainable asphalt modifier. In this research it is focused on the investigation work of the asphalt binder modified properties with different percentages of one different micro material. This material is Parit Nipah Peat. The investigation is about the physical properties of asphalt binders modified with Parit Nipah Peat PNpt.M.A. PNpt leads to make a lot of changes in internal and external of the samples that checked via penetration test, ductility test, and Scanning Electron Microscopic. The Parit Nipah Peat was added to the original binder with a high shear blender then used at 1500 rpm to mix the PNpt with the binder. Three (3) different percentages were mixed by weight of binder to modify the asphalt binder with the binder at 0, 3%, 5% and 7%. This material has a high ability to distribution with asphalt, appears to be plain and homogeneous and different structure after blended with bitumen. The physical property of modified binders enhanced the binder properties, as the results of penetration test, ductility test and distribution inside the binder showed that. Adding a different concentration of PNpt to base binder had significant effects of high resistant changing volume and increased hardness.
