Test of Microstructur Permeable Asphalt Pavement Used Domato Stone (Quarsite Dolomite) As Course Agregate for Surface Layer of Road Pavement

摘要

The experiment works was dividing into two phases, for phase one was developed to investigate the properties of aggregates and straight asphalt qualities. The experiment work for phase two was developed to design the porous asphalt mix. In this phase Japan's method and Binamarga's method was used to define optimum asphalt content. In this phase, has result cantabro loss weight 77.10 for asphalt quality 3% and loss weight 9.70 for asphalt quality 5%. asphalt flow down, air void and density values. The experiment work for phase two was developed to investigate the qualities of porous asphalt. In this phase, wheel tracking machine test was used to investigate the dynamic stability of mixes. Result of this research will be valuable for development porous asphalt technology. Based on the Scanning Electron Microscope (SEM) can be seen the microstructure and content of chemical elements present in the porous asphalt. : Oxygen 58.46%, Silicon 2.60%, Aluminium 2.91%, Sodium 5.75%, Calcium 19.11%, Sulfur 7.83%, Magnesium 3.52%, SiO2 6.73%, Al2O3 6.40%, Na2O 7.45%, CaO 46.25%, SO3 27.05%, MgO 6.12%.
