Abstract: 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. [ABSTRACT FROM AUTHOR]
