A study was previously conducted in Universiti Teknologi Petronas(UTP) on the uses of geopolymer in porous asphalt, and it was discovered that using adding geopolymer on porous asphalt gives the substance a higher value of stiffness and stability compared to conventional pavement being used nowadays. This finding sparks the initiative to further investigate the properties of geopolymer bituminous mixtures, with the ultimate goal to study the potential capability of the substance to commercially replace the use of conventional pavement. The project "Creep Properties of Geopolymer Bituminous Mixtures" is a continuation of the previous study, with the aim to investigate the creep properties of geopolymer bituminous mixtures, and thus predicting the rut potential of the material. This project is an important component in an effort to investigate the suitability of geopolymer bituminous mixtures for its potential commercial use in the future. Much of the drive behind research carried out in academic institutions these days is to investigate the development of geopolymer cements as a potential large-scale replacement for concrete produced from Portland cement. This is due to geopolymers' alleged lower carbon dioxide production emissions, greater chemical and thermal resistance and better mechanical properties at both ambient and extreme conditions. Addition of geopolymer to porous asphalt to produce a new type of pavement material is a new idea which seeks to exploit these valuable properties of geopolymer, which is beneficial in pavement design. In short, the use of geopolymer on bituminous mixtures therefore carries the prospect of combining these properties of geopolymer and porous asphalt to develop a material that is environmental friendly and durable at a competitive cost for use in pavement.
