Preliminary Study on Compressive Strength of Porous Asphalt Containing Modified Buton Asphalt, Waste Plastic and Limestone Powder

Abstract

Abstract Porous asphalt is a surface layer or a wear layer is one of the asphalt material developed to overcome the problem of inundation during the rainy season making it suitable for use in Indonesia which has high rainfall intensity. Furthermore, it is necessary to optimize the use of a number of natural resources in Indonesia such as natural rock asphalt in Buton Island (BRA) and limestone which is available in many places. In addition, reducing of plastic waste is attracts the attention of a number of countries including Indonesia. This paper is part of a series of investigate study related to the behaviour of porous asphalt mixture made with modified Buton asphalt (MBA), waste plastic and lime stone powder. The compaction results showed good adhesion can unite the waste Polyethylene terephthalate (PET), limestone powder and coarse aggregate particles. There is no visible negative effect of waste PET and limestone powder in porous asphalt mixture against compressive strength.
