Abstract:Porous pavements are receiving increased attention in modern days in terms of their ability to improve stormwater management while creating sustainable pavements. In this paper, a porous pavement system is designed and evaluated for its performance in terms of a piezoelectric energy harvesting mechanism. The primary objective of this paper is to evaluate the mechanical properties of porous pavements using different percentages of fine aggregate replacement in terms of their ability to harvest energy. An experimental investigation was carried out on porous pavements in terms of cube specimens using different percentages of fine aggregate replacement, i.e., 0%, 5%, and 10% fine aggregate replacement in terms of 8mm size. The experimental results show that an increase in fine aggregate replacement percentages results in an increase in both compressive load and stress values for different curing periods. At 28 days of curing period, the porous pavements containing 10% fine aggregate replacement show better results in terms of both compressive load and stress values compared to other percentages of fine aggregate replacement. The compressive stress values for porous pavements containing 10% fine aggregate replacement are 1.728 MPa and a compressive load of 38.9 kN, while for 0% fine aggregate replacement, the values are 1.351 MPa and 30.4 kN. Similar results are obtained for 7 and 14 days of curing periods. The improved mechanical properties of porous pavements make them suitable for energy harvesting applications.
