Polyurethane pervious concrete has gained significant attention in urban pavement applications due to its rapid construction, wide color range, and improved comfort underfoot. This material offers a promising alternative for sustainable and aesthetically adaptable pavements. Research has focused on optimizing the aggregate-to binder ratio to balance key properties such as compressive strength, surface porosity, and water permeability. Experimental results indicate that a 30:1 aggregate-to-binder ratio achieves the best compromise, providing approximately 5 MPa compressive strength and 11.45 mm/s permeability. While increasing aggregate content enhances surface porosity, most pores remain isolated, limiting permeability improvement. Thermal aging tests revealed an initial increase in strength due to polymerization, followed by a decline from oxidation. Red specimens exhibited higher resistance to heat degradation compared to green and yellow ones. UV exposure had a less significant effect, but red specimens again demonstrated superior durability. High-humidity conditions severely reduced compressive strength, with a 26% loss after fourteen days, highlighting vulnerability to water vapor. The study is limited to laboratory-scale testing, utilizing only iron oxide pigments, without field validation or evaluation of alternative pigments. Additionally, drainage system design and freeze-thaw performance were not assessed. Future research should focus on enhancing water vapor resistance through modified binder compositions or surface treatments, testing other pigments, evaluating freeze-thaw durability, and validating performance in real-world field conditions. These steps will provide a comprehensive understanding of polyurethane pervious concrete’s durability, functionality, and practical applicability in urban infrastructure projects.
