Considering the correct disposal of the significant volume of polyethylene terephthalate (PET) waste generated worldwide, interlocking concrete block pavement can be an alternative. Thus, in this study, the performance of interlocking blocks produced with partial replacement of fine aggregate by micronized PET in the percentages of 2.5, 5.0, 7.5, and 10.0% was evaluated. The results indicated that the values of compressive strength, modulus of elasticity, and flexural strength decreased with the increase in PET percentage. The blocks exhibited good abrasion resistance and resistance to sulfate attack. Therefore, the results indicate the promising application of PET for paving blocks.

考虑到正确处置世界范围内产生的大量聚对苯二甲酸乙二醇酯 (PET) 废物，互锁混凝土砌块路面可以成为替代方案。因此，在本研究中，评估了用微粉化 PET 以 2.5、5.0、7.5 和 10.0% 的百分比部分替代细骨料生产的互锁块的性能。结果表明，压缩强度、弹性模量和弯曲强度的值随着PET百分比的增加而降低。块体表现出良好的耐磨性和抗硫酸盐侵蚀性。因此，结果表明 PET 在铺路砖中的应用前景广阔。
