摘要

This article presents an investigation on enhancing the performance of pervious concrete pavement (PCP) through the incorporation of a geocell layer. PCP models were fabricated with different base layers with and without geocells. Load tests were performed using a strain-controlled loading frame under a uniform pressure of 565 kPa, simulating single-wheel loading conditions across all tests. The results showed significant improvements when the base layer was reinforced with a geocell. Settlement was reduced by 45.23%, vertical stress decreased by 42.43%, and pore water pressure dropped by 39.75%, collectively contributing to improved structural integrity and drainage performance. Comprehensive finite element simulations were also conducted, utilizing accurate geocell geometries within a rigorously developed PCP model that addressed key challenges. These analyses were extended to include moving loads to assess dynamic performance. A robust validation procedure demonstrated strong agreement between experimental data and numerical simulation results, with errors below 10%, confirming the reliability of both methodologies.
