The systematic behavior of porous asphalt pavement (PAP) under normal traffic conditions has been studied in detail in the present work. In the first phase, an observation program measured the stability by Marshall Test for all the prepared design mix samples with normal bitumen (60/ 70). For the permeability test in the second phase of observation, a model is developed in the laboratory on the same falling head permeability test. The maximum permeability reaches 0.394 cm/sec for a fresh sample and 0.245 cm/sec after one year of environmental exposure. The maximum stability was 26.9 kN, and the average value obtained was 21 kN. The present work approach provides effectively reliable results in terms of stability and permeability of porous asphalt mix. The primary goal of this research is to reduce the possibility of floods and increase driver protection during inclement weather. A particular emphasis was placed on the mix ratio differences between aggregates to achieve the desired permeability while maintaining the necessary stability. The findings indicate that the checked sample looked excellent in terms of permeability.
