This study focuses on investigating the possibility of using pelletized HDPE (post-consumer high-density polyethylene plastic) as a partial replacement for ready-mixed concrete in the construction of cycle paths using Portland concrete slabs. The choice of HDPE is based on its mechanical properties and environmental impact, as a significant percentage of produced and consumed plastic does not undergo a complete cycle of consumption and recycling, ending up in landfills. To determine the viability of this substitution, analyses and reviews of relevant research were conducted. Specific replacement percentages were established: 5%, 7.5%, and 10% for ready-mixed concrete (210 kg/m²). These modified mixtures were evaluated according to the NTP 339.078 standard. The results showed that, although there was a decrease in concrete strength when HDPE was incorporated, the resulting strength still met the necessary standards (NTP 010 Urban Pavements) for cycle path construction. Among the tested percentages, it was found that adding 10% HDPE to the concrete slightly exceeded the flexural strength of the standard concrete of 175 kg/cm². However, it was determined that the 7.5% proportion was the most suitable. This dosage maintained a flexural strength (41.20 kg-f/cm²) that met the requirements while allowing for a higher incorporation of HDPE into the mixture. This achieved a balance between structural integrity, environmental efficiency, and economic viability in cycle path construction.
