<p>Green construction is increasingly recognized as a necessity to reduce the environmental footprint of the building sector. This study investigates the feasibility of utilizing clay brick waste powders (CBWPs) and recycled fibers in the production of sustainable concrete for pavement applications. Seven concrete mixes were prepared, in which 30% of the cement was replaced by a collective CBWP blend consisting of 8.5% red perforated brick powder (RPBP), 10.75% yellow perforated brick powder (YPBP), and 10.75% yellow solid brick powder (YSBP), with a total binder content of 535 kg/m³. In addition, recycled Polyethylene Terephthalate (PET) and glass fibers, either individually or in combination, were introduced into five of the mixes to enhance performance. The results revealed that CBWP replacement slightly reduced the workability of fresh mixtures, requiring the use of superplasticizer to maintain slump comparable to the reference mix. However, significant mechanical improvements were achieved: incorporating 1% PET fibers increased compressive strength by 22.22% at 28 days, while combining 0.75% PET fibers with 0.25% glass fibers enhanced flexural strength by approximately 81.48%. Furthermore, the impact resistance of green high-performance fiber-reinforced concrete (GHPFRC) improved by up to 500% compared with normal concrete. These findings demonstrate that incorporating CBWPs with recycled PET and glass fibers offers a practical approach for producing sustainable pavement concrete, while simultaneously reducing construction waste and plastic accumulation in landfills.</p>
